Properties

Atr
Atr As String (read-only)
Introduced in version 9.5.0.87

The ATR of the card in the reader. This property is set by the AquireContext method.

top
CardName
CardName As String (read-only)
Introduced in version 9.5.0.87

The name of the card in the reader. This property is set by the AquireContext method.

top
DebugLogFilePath
DebugLogFilePath As String

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
LastBinaryResult
LastBinaryResult As Variant (read-only)
Introduced in version 9.5.0.52

The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to 1. This provides a means for obtaining large varbinary results in the SQL Server environment (where limitations exist in getting large amounts of data returned by method calls, but where temp tables can be used for binary properties).

top
LastErrorHtml
LastErrorHtml As String (read-only)

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
LastErrorText As String (read-only)

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
LastErrorXml As String (read-only)

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
LastMethodSuccess As Long
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
LastStringResult
LastStringResult As String (read-only)
Introduced in version 9.5.0.52

The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to 1. This provides a means for obtaining large string results in the SQL Server environment (where limitations exist in getting long strings returned by method calls, but where temp tables can be used for string properties).

top
LastStringResultLen
LastStringResultLen As Long (read-only)
Introduced in version 9.5.0.53

The length, in characters, of the string contained in the LastStringResult property.

top
MaxContainers
MaxContainers As Long (read-only)
Introduced in version 9.5.0.87

The maximum number of key containers available. The 1st key container is at index 0. Each key container can potentially contain one signature key, and one key exchange key.

top
RsaPaddingHash
RsaPaddingHash As String
Introduced in version 9.5.0.87

If an RSA key is used for signing, this is the hash algorithm to used in conjunction with the padding scheme. It can be "SHA1", "SHA256", "SHA384", or "SHA512". The default is "SHA256".

top
RsaPaddingScheme
RsaPaddingScheme As String
Introduced in version 9.5.0.87

If an RSA key is used for signing, this is the padding scheme to use. It can be "PKCS" or "PSS". The default is "PSS".

top
UncommonOptions
UncommonOptions As String
Introduced in version 9.5.0.87

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

top
VerboseLogging
VerboseLogging As Long

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
Version As String (read-only)

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

top

Methods

AcquireContext
AcquireContext(readerName As String) As Long
Introduced in version 9.5.0.87

Initializes communication with the card inserted in the given reader. Reader names can be discovered via the SCard.ListReaders or SCard.FindSmartcards methods. If successful, the Atr and CardName properties will be set.

Returns 1 for success, 0 for failure.

top
CardDeleteFile
CardDeleteFile(dirName As String, fileName As String) As Long
Introduced in version 9.5.0.88

Deletes the file specified by dirName and fileName. dirName is the name of the directory that contains the file, or the empty string for root.

Returns 1 for success, 0 for failure.

top
DeleteCert
DeleteCert(cert As ChilkatCert, ByVal delPrivKey As Long) As Long
Introduced in version 9.5.0.88

Deletes a certificate and optionally its associated private key from the smart card. If delPrivKey is 1, then the associated private key, if it exists, is also deleted.

Returns 1 for success, 0 for failure.

top
DeleteContext
DeleteContext() As Long
Introduced in version 9.5.0.87

This function reverses the effect of AcquireContext and severs the communication between the Base CSP/KSP and the card minidriver. The Atr and CardName properties are cleared.

Returns 1 for success, 0 for failure.

top
DeleteKeyContainer
DeleteKeyContainer(ByVal containerIndex As Long) As Long
Introduced in version 9.5.0.87

Deletes the key container at the given containerIndex. This deletes both the "signature" and "key exchange" keys that may be contained in the specified key container.

top
EnumFiles
EnumFiles(dirName As String, st As ChilkatStringTable) As Long
Introduced in version 9.5.0.87

Get the list of files in the directory specified by dirName. Pass the empty string for the root directory. The filenames are returned in st.

Returns 1 for success, 0 for failure.

top
FindCert
FindCert(certPart As String, partValue As String, cert As ChilkatCert) As Long
Introduced in version 9.5.0.87

Finds the certificate where the given certPart equals the partValue. Possible values for certPart are: "subjectDN", "subjectDN_withTags", "subjectCN", "serial", or "serial:issuerCN".

The cert is loaded with the certificate if successful.

Note: If successful, the cert will be linked internally with this ScMinidriver session such that certificate can be used for signing on the smart card when used in other Chilkat classes such as XmlDSigGen, Pdf, Crypt2, Mime, MailMan, etc.

Returns 1 for success, 0 for failure.

top
GenerateKey
GenerateKey(ByVal containerIndex As Long, keySpec As String, keyType As String, ByVal keySize As Long, pinId As String) As Long
Introduced in version 9.5.0.87

Generates a key to be stored in either the "signature" or "key exchange" location within a key container. Creates the key container if it does not already exist. Otherwise replaces the key in the key container.

The keySpec can be "sig" or "kex" to specify either the "signature" or "key exchange" location.

The keyType can be "ecc" or "rsa".

For RSA keys, the keySize is the size of the key in bits, such as 1024, 2048, 4096, etc. (2048 is a typical value.) For ECC keys, the size can be 256, 384, or 521.

The pinId can be "user", or "3" through "7". (It is typically "user".)

Returns 1 for success, 0 for failure.

top

Get the certificate at the specified containerIndex and keySpec. The keySpec can be "sig" or "kex" to specify either the "signature" or "key exchange" location within the container. The containerIndex can be -1 to choose the first key container with a certificate. The keySpec can also be "any" to choose either "sig" or "kex" based on which is present, with preference given to "sig" if both are present.

The cert is loaded with the certificate if successful.

Note: If successful, the cert will be linked internally with this ScMinidriver session such that certificate can be used for signing on the smart card when used in other Chilkat classes such as XmlDSigGen, Pdf, Crypt2, Mime, MailMan, etc.

Returns 1 for success, 0 for failure.

top
GetContainerKeys
GetContainerKeys(ByVal containerIndex As Long, sigKey As PublicKey, kexKey As PublicKey) As Long

Returns 1 for success, 0 for failure.

top
ImportCert
ImportCert(cert As ChilkatCert, ByVal containerIndex As Long, keySpec As String, pinId As String) As Long
Introduced in version 9.5.0.87

The cert must have an accessible private key, such as will be the case if the cert was loaded from a .pfx/.p12, or if the cert was loaded from a Windows certificate store where the private key exists (and can be exported from the Windows certificate store).

The containerIndex is the container index. It can range from 0 to the MaxContainers-1.

The keySpec can be "sig" or "kex" to specify either the "signature" or "key exchange" location within the container.

The pinId can be "user", or "3" through "7". (It is typically "user".)

Returns 1 for success, 0 for failure.

top
ImportKey
ImportKey(ByVal containerIndex As Long, keySpec As String, privKey As PrivateKey, pinId As String) As Long
Introduced in version 9.5.0.87

Imports a key to be stored in either the "signature" or "key exchange" location within a key container. Creates the key container if it does not already exist. Otherwise replaces the specified key in the key container.

The keySpec can be "sig" or "kex" to specify either the "signature" or "key exchange" location.

The privKey is the private key to import.

The ARG5 can be "user", or "3" through "7". (It is typically "user".)

Returns 1 for success, 0 for failure.

top
ListCerts
ListCerts(certPart As String, st As ChilkatStringTable) As Long

Lists the certs found on the smart card. The certPart indicates the information to be returned from each certificate. Possible values are: "subjectDN", "subjectDN_withTags", "subjectCN", "serial", or "serial:issuerCN". The information is returned in st.

Returns 1 for success, 0 for failure.

top
PinAuthenticate
PinAuthenticate(pinId As String, pin As String) As Long
Introduced in version 9.5.0.87

Performs regular PIN authentication. The pinId can be "user", "admin", or "3" through "7". (It is typically "user".) The pin is the alphanumeric PIN.

Returns 0 for success. If not successful, the return value indicates the number of attempts remaining before the PIN is locked. (The number of times an incorrect PIN may be presented to the card before the PIN is blocked, and requires the admin to unblock it.) If the PIN is already blocked, the return value is -1. If the method fails for some other reason, such as if a context has not yet been acquired, the return value is -2.

top
PinAuthenticateHex
PinAuthenticateHex(pinId As String, pin As String) As Long
Introduced in version 9.5.0.87

The same as PinAutheneticate, but the PIN is passed as a hex string. For example, to pass a PIN of 0x01, 0x02, 0x03, 0x04, pass "01020304".

top
PinChange
PinChange(pinId As String, currentPin As String, newPin As String) As Long
Introduced in version 9.5.0.87

Changes a PIN. The pinId can be "user", "admin", or "3" through "7". (It is typically "user".) The currentPin is the current alphanumeric PIN. The newPin is the new PIN.

Returns 0 for success. If not successful, the return value indicates the number of attempts remaining before the PIN is locked. (The number of times an incorrect PIN may be presented to the card before the PIN is blocked, and requires the admin to unblock it.) If the PIN is already blocked, the return value is -1. If the method fails for some other reason, such as if a context has not yet been acquired, the return value is -2.

top
PinDeauthenticate
PinDeauthenticate(pinId As String) As Long
Introduced in version 9.5.0.87

Reverses a previous PIN authentication without resetting the card. The pinId can be "user", "admin", or "3" through "7". (It is typically "user".)

Returns 1 for success, 0 for failure.

top
ReadFile
ReadFile(dirName As String, fileName As String, bd As ChilkatBinData) As Long
Introduced in version 9.5.0.87

Reads the entire file specified by dirName and fileName into bd. dirName is the name of the directory that contains the file, or the empty string for root.

Returns 1 for success, 0 for failure.

top
SignData
SignData(ByVal containerIndex As Long, keySpec As String, hashDataAlg As String, bdData As ChilkatBinData, bdSignedData As ChilkatBinData) As Long
Introduced in version 9.5.0.87

Signs the data passed in bdData. The hashDataAlg can be "sha1", "sha256", "sha384", "sha512", or "none". If not equal to "none", then the hash of the data passed in bdData is signed.

The containerIndex specifies the key container. By specifying the key container, you are almost specifying the key. A key container can contain two keys: A signature key, and a key-exchange key. The keySpec indicates which of these two keys to use. keySpec should be set to "sig" or "kex".

Note: The type of signature created, such as RSA or ECC, is determined by the type of key that exists in the key container (specified by containerIndex and keySpec). If it is an RSA key, additional options can be specified via the RsaPaddingScheme and RsaPaddingHash properties.

If successful, the signature is written to bdSignedData.

Returns 1 for success, 0 for failure.

top
WriteFile
WriteFile(dirName As String, fileName As String, bd As ChilkatBinData) As Long
Introduced in version 9.5.0.87

Writes the entire file specified by dirName and fileName. dirName is the name of the directory that contains the file, or the empty string for root. The entire contents of bd are written to the file on the smart card.

Returns 1 for success, 0 for failure.
