Pfx Tcl Reference Documentation

Pfx

Current Version: 9.5.0.87

Provides the ability to manage, parse, and read PFX (PKCS12) files. To create PFX (PKCS12) files, use the certificate object's ExportToPfxFile or ExportToPfxData methods.

Properties

AlgorithmId
string
# ckStr is a CkString
CkPfx_get_AlgorithmId $myPfx $ckStr
set strVal [CkPfx_get_algorithmId $myPfx]
CkPfx_put_AlgorithmId $myPfx $strVal
Introduced in version 9.5.0.83

The encryption algorithm to be used when writing a PFX. After loading a PFX, this property is set to the encryption algorithm used by the loaded PFX. (This is the algorithm used for the "shrouded key bag", which is internal to the PFX.)

The default value (for backward compatibility) is "pbeWithSHAAnd3_KeyTripleDES_CBC". Can be set to "pbes2", in which case the Pbes2CryptAlg and Pbes2HmacAlg properies will be set to the algorithms to be used when writing, or the algorithms used by the loaded PFX.

DebugLogFilePath
string
# ckStr is a CkString
CkPfx_get_DebugLogFilePath $myPfx $ckStr
set strVal [CkPfx_get_debugLogFilePath $myPfx]
CkPfx_put_DebugLogFilePath $myPfx $strVal

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

top
LastErrorHtml
string
# ckStr is a CkString
CkPfx_get_LastErrorHtml $myPfx $ckStr
set strVal [CkPfx_get_lastErrorHtml $myPfx]

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorText
string
# ckStr is a CkString
CkPfx_get_LastErrorText $myPfx $ckStr
set strVal [CkPfx_get_lastErrorText $myPfx]

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorXml
string
# ckStr is a CkString
CkPfx_get_LastErrorXml $myPfx $ckStr
set strVal [CkPfx_get_lastErrorXml $myPfx]

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastMethodSuccess
boolean 1/0
set boolVal [CkPfx_get_LastMethodSuccess $myPfx]
CkPfx_put_LastMethodSuccess $myPfx $boolVal
Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of 1 indicates success, a value of 0 indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = 1 and failure = 0.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to 1. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
NumCerts
integer
set intVal [CkPfx_get_NumCerts $myPfx]
Introduced in version 9.5.0.40

The number of certificates contained in the PFX.

top
NumPrivateKeys
integer
set intVal [CkPfx_get_NumPrivateKeys $myPfx]
Introduced in version 9.5.0.40

The number of private keys contained in the PFX.

top
Pbes2CryptAlg
string
# ckStr is a CkString
CkPfx_get_Pbes2CryptAlg $myPfx $ckStr
set strVal [CkPfx_get_pbes2CryptAlg $myPfx]
CkPfx_put_Pbes2CryptAlg $myPfx $strVal
Introduced in version 9.5.0.83

If the AlgorithmId property equals "pbes2", then this is the encryption algorithm to be used when writing the PFX, or used by the PFX that was loaded. If the AlgorithmId is not equal to "pbes2", then the value of this property is meaningless.

Possible values are:

  • aes256-cbc
  • aes192-cbc
  • aes128-cbc
  • 3des-cbc

The default value (for writing) is "aes256-cbc". Note: The algorithm specified by this property is only used when the Algorithmid = "pbes2".

Pbes2HmacAlg
string
# ckStr is a CkString
CkPfx_get_Pbes2HmacAlg $myPfx $ckStr
set strVal [CkPfx_get_pbes2HmacAlg $myPfx]
CkPfx_put_Pbes2HmacAlg $myPfx $strVal
Introduced in version 9.5.0.83

If the AlgorithmId property equals "pbes2", then this is the HMAC hash algorithm to be used when writing the PFX, or used by the PFX that was loaded. If the AlgorithmId is not equal to "pbes2", then the value of this property is meaningless.

Possible values are:

  • hmacWithSha256
  • hmacWithSha384
  • hmacWithSha512
  • hmacWithSha1

The default value (for writing) is "hmacWithSha256". Note: The algorithm specified by this property is only used when the Algorithmid = "pbes2".

UncommonOptions
string
# ckStr is a CkString
CkPfx_get_UncommonOptions $myPfx $ckStr
set strVal [CkPfx_get_uncommonOptions $myPfx]
CkPfx_put_UncommonOptions $myPfx $strVal
Introduced in version 9.5.0.83

This is a catch-all property to be used for uncommon needs. This property defaults to the empty string and should typically remain empty.

Can be set to a list of the following comma separated keywords:

  • "LegacyOrder" - Introduced in v9.5.0.83. Write the internal ContentInfos in the order Chilkat traditionally used in previous versions.
  • "NoTruncatePfxPassword64" - Introduced in v9.5.0.87. Microsoft systems/tools such as certmgr.msc would typically truncate extremely long passwords to 64 bytes/chars. Other systems did not. Chilkat will by default truncate passwords to 64 chars. Add this keyword to prevent truncation.

top
Utf8
boolean 1/0
set boolVal [CkPfx_get_Utf8 $myPfx]
CkPfx_put_Utf8 $myPfx $boolVal

When set to 1, all "const char *" arguments are interpreted as utf-8 strings. If set to 0 (the default), then "const char *" arguments are interpreted as ANSI strings. Also, when set to 1, and Chilkat method returning a "const char *" is returning the utf-8 representation. If set to 0, all "const char *" return values are ANSI strings.

top
VerboseLogging
boolean 1/0
set boolVal [CkPfx_get_VerboseLogging $myPfx]
CkPfx_put_VerboseLogging $myPfx $boolVal

If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
string
# ckStr is a CkString
CkPfx_get_Version $myPfx $ckStr
set strVal [CkPfx_get_version $myPfx]

Version of the component/library, such as "9.5.0.63"

Methods

AddCert
# cert is a CkCert
# includeChain is a boolean
set status [CkPfx_AddCert $cert $includeChain]
Introduced in version 9.5.0.44

Adds a certificate, its private key (if it exists), and potentially its certificate chain to the PFX. If includeChain is 1, then the certificate must have a private key. The certificate's private key is automatically obtained (internally) via the cert's ExportPrivateKey method. If the certificate's chain of authentication is to be added, it is automatically constructed and added using whatever resources are at hand (such as certs provided via the UseCertVault method, the trusted roots from Chilkat's TrustedRoots class, etc. If a certificate chain is to be added, which is the typical case, then the chain must be completed to the root to succeed.

Returns 1 for success, 0 for failure.

top
AddPrivateKey
# privKey is a CkPrivateKey
# certChain is a CkCertChain
set status [CkPfx_AddPrivateKey $privKey $certChain]
Introduced in version 9.5.0.44

Adds a private key and certificate chain to the PFX. The private key should be such that it is associated with the 1st certificate in the chain. In other words, the 1st certificate in the chain has a public key (embedded within the X.509 structure of the cert itself) that is the counterpart to the private key.

Returns 1 for success, 0 for failure.

top
FindCertByLocalKeyId
# returns a CkCert
# localKeyId is a string
# encoding is a string
set ret_cert [CkPfx_FindCertByLocalKeyId $localKeyId $encoding]
Introduced in version 9.5.0.83

Finds and returns the certificate (in the PFX) that has a cert bag "localKeyId" attribute with the specified value. The localKeyId is specifid using the encoding (such as "decimal", "base64", "hex") specified by encoding.

Returns NULL on failure

top
GetCert
# returns a CkCert
# index is an integer
set ret_cert [CkPfx_GetCert $index]
Introduced in version 9.5.0.40

Returns the Nth certificate in the PFX. (The 1st certificate is at index 0.)

Returns NULL on failure

top
GetPrivateKey
# returns a CkPrivateKey
# index is an integer
set ret_privateKey [CkPfx_GetPrivateKey $index]
Introduced in version 9.5.0.40

Returns the Nth private key in the PFX. (The 1st private key is at index 0.)

Returns NULL on failure

top
GetSafeBagAttr
# forPrivateKey is a boolean
# index is an integer
# attrName is a string
# outStr is a CkString (output)
set status [CkPfx_GetSafeBagAttr $forPrivateKey $index $attrName $outStr]
set retStr [CkPfx_getSafeBagAttr $myPfx $forPrivateKey $index $attrName]
Introduced in version 9.5.0.83

Can be called to get one of the following safebag attributes for the Nth private key or certificate in the PFX. forPrivateKey should be 1 for a private key, and 0 for a certificate. The index is the index of the certificate or key in the PFX. The attrName can be one of the following:

  • "localKeyId" : Returns the decimal representation of the local key ID. The local key ID is used to associate the certificate contained in the PFX with this private key. (The certificate will include a "localKeyId" attribute in its cert bag of attributes within the PFX.)
  • "keyContainerName" : Returns the key container name (or key name) of the private key. For more information about the directories where the Windows OS stores private keys, see https://docs.microsoft.com/en-us/windows/win32/seccng/key-storage-and-retrieval
  • "storageProvider" : Returns the name of the Cryptographic Storage Provider to be used for the key.

Note: It is not required that any of the above attributes are present in the PFX.

Returns 1 for success, 0 for failure.

ImportToWindows
# exportable is a boolean
# userProtected is a boolean
# machineKeyset is a boolean
# allowOverwriteKey is a boolean
# allowExport is a boolean
# leafStore is a string
# intermediateStore is a string
# rootStore is a string
# extraOptions is a string
set status [CkPfx_ImportToWindows $exportable $userProtected $machineKeyset $allowOverwriteKey $allowExport $leafStore $intermediateStore $rootStore $extraOptions]
Introduced in version 9.5.0.83

Imports the certificates and private keys contained in the PFX to Windows certificate store(s).

If exportable is 1, imported keys are marked as exportable.

If userProtected is 1, the user is to be notified through a dialog box or other method when certain attempts to use this key are made. The precise behavior is specified by the cryptographic service provider (CSP) being used.

If machineKeyset is 1, the private keys are stored under the local computer and not under the current user.

If allowOverwriteKey is 1, allow overwrite of the existing key. Specify this flag when you encounter a scenario in which you must import a PFX file that contains a key name that already exists. For example, when you import a PFX file, it is possible that a container of the same name is already present because there is no unique namespace for key containers. If you have created a "TestKey" on your computer, and then you import a PFX file that also has "TestKey" as the key container, this flag allows the key to be overwritten.

if allowExport is 1, then the key is marked as exportable, which allows for it to be re-exported to a PFX.

The leafStore, intermediateStore, and rootStore are the Windows certificate store names indicating where to import certificates of each given type. A leafStore is a certificate that is not the issuer of any other certificate in the PFX. An intermediateStore is any certificate that is not a root (or self-signed) but is also the issuer of some other certificate in the PFX. A rootStore is a self-signed or root certificate.

The possible store names for leafStore, intermediateStore, and rootStore are as follows:

  • "None": Do not import certificates of the given type into any Windows certicate store.
  • "AddressBook": Certificate store for other users.
  • "AuthRoot": Certificate store for third-party certification authorities (CAs).
  • "CertificationAuthority": Certificate store for intermediate certification authorities (CAs).
  • "My": Certificate store for personal certificates. (Leaf certificates are typically imported into this store.)
  • "Root": Certificate store for trusted root certification authorities (CAs).
  • "TrustedPeople": Certificate store for directly trusted people and resources.
  • "TrustedPublisher": Certificate store for directly trusted publishers.

The rootStore is reserved for any future options that may be needed. At this time, pass an empty string.

Returns 1 for success, 0 for failure.

# pfxData is a CkByteData
# password is a string
set status [CkPfx_LoadPfxBytes $pfxData $password]
Introduced in version 9.5.0.40

Loads a PFX from in-memory bytes.

If the .pfx/.p12 uses different passwords for integrity and private keys, then the password argument may contain JSON to specify the passwords. See the LoadPfxFile method (below) for details.

Returns 1 for success, 0 for failure.

top
LoadPfxEncoded
# encodedData is a string
# encoding is a string
# password is a string
set status [CkPfx_LoadPfxEncoded $encodedData $encoding $password]
Introduced in version 9.5.0.40

Loads a PFX from encoded byte data. The encoding can by any encoding, such as "Base64", "modBase64", "Base32", "UU", "QP" (for quoted-printable), "URL" (for url-encoding), "Hex", "Q", "B", "url_oath", "url_rfc1738", "url_rfc2396", and "url_rfc3986".

If the .pfx/.p12 uses different passwords for integrity and private keys, then the encoding argument may contain JSON to specify the passwords. See the LoadPfxFile method (below) for details.

Returns 1 for success, 0 for failure.

top
LoadPfxFile
# path is a string
# password is a string
set status [CkPfx_LoadPfxFile $path $password]
Introduced in version 9.5.0.40

Loads a PFX from a file.

Starting in v9.5.0.75, a .pfx/.p12 file with different passwords for integrity and private keys can be loaded by passing the following JSON for the password.

    {
      "integrity": "password1",
      "privKeys": "password2",
     }
If it is desired to open the .pfx/.p12 without access to the private keys, then add "skipPrivateKeys" like this:
    {
      "integrity": "password1",
      "privKeys": "not used",
       "skipPrivateKeys": true
     }

Returns 1 for success, 0 for failure.

SetSafeBagAttr
# forPrivateKey is a boolean
# index is an integer
# name is a string
# value is a string
# encoding is a string
set status [CkPfx_SetSafeBagAttr $forPrivateKey $index $name $value $encoding]
Introduced in version 9.5.0.83

Sets a safe bag attribute for the Nth private key or certificate in the PFX. Safe bag attributes can be added by calling this method once for each attribute to be added to each certificate or key. forPrivateKey should be 1 for a private key, and 0 for a certificate. The index is the index of the certificate or key in the PFX. (The 1st item is at index 0.) See the example below for more information. The encoding indicates a binary encoding such as "base64", "hex", "decimal", "fingerprint", etc if the value contains binary (non-text) data.

A safe bag attribute can be removed by passing an empty string for the value.

Returns 1 for success, 0 for failure.

Returns 1 for success, 0 for failure.

top
ToJavaKeyStore
# returns a CkJavaKeyStore
# alias is a string
# password is a string
set ret_javaKeyStore [CkPfx_ToJavaKeyStore $alias $password]
Introduced in version 9.5.0.44

Converts the PFX (PKCS12) to a JavaKeyStore object. One JKS entry per private key found in the PKCS12 is added. The certs found within the PCKS12 are used to build the certificate chains for each private key. (A typical PFX file contains a single private key along with its associated certificate, and the certificates in the chain of authentication to the root CA cert.)

The specified alias is applied to the 1st private key found. If the alias is empty, then the alias is obtained from the cert/PFX in the following order of preference:

  1. Certificate's subject common name
  2. Certificate's subject email address
  3. Certificate's friendly name found in the PKCS9 attributes of the PKCS12
  4. Certificate's serial number

If multiple private keys are found in the PKCS12, then all but the first will automaticallly be assigned aliases using the preference just described.

Returns NULL on failure

set retStr [CkPfx_toPemEx $myPfx $extendedAttrs $noKeys $noCerts $noCaCerts $encryptAlg $password]
Introduced in version 9.5.0.49

Write the PFX to a PEM formatted string. If extendedAttrs is 1, then extended properties (Bag Attributes and Key Attributes) are output. If noKeys is 1, then no private keys are output. If noCerts is 1, then no certificates are output. If noCaCerts is 1, then no CA certs or intermediate CA certs are output. If encryptAlg is not empty, it indicates the encryption algorithm to be used for encrypting the private keys (otherwise the private keys are output unencrypted). The possible choices for the encryptAlg are "des3", "aes128", "aes192", and "aes256". (All encryption algorithm choices use CBC mode.) If the private keys are to be encrypted, then password is the password to be used. Otherwise, password may be left empty. For example:
