JavaKeyStore VB.NET Reference Documentation

JavaKeyStore

Current Version: 9.5.0.75

API to read, write, access, and update Java key stores (JKS format).

This class also supports the JCEKS format starting in Chilkat v9.5.0.66.

Object Creation

Dim obj As New Chilkat.JavaKeyStore()

Properties

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
LastErrorHtml
LastErrorHtml As String (ReadOnly)

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 (ReadOnly)

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 (ReadOnly)

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 Boolean
Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of True indicates success, a value of False 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 = True and failure = False.
  • 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 True. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
NumPrivateKeys
NumPrivateKeys As Integer (ReadOnly)
Introduced in version 9.5.0.44

The number of private keys contained within the keystore. Each private key has an alias and certificate chain associated with it.

top
NumSecretKeys
NumSecretKeys As Integer (ReadOnly)
Introduced in version 9.5.0.66

The number of secret keys (such as AES keys) contained within the keystore. Each secret key can have an alias associated with it.

More Information and Examples
top
NumTrustedCerts
NumTrustedCerts As Integer (ReadOnly)
Introduced in version 9.5.0.44

The number of trusted certificates contained within the keystore. Each certificate has an alias (identifying string) associated with it.

top
RequireCompleteChain
RequireCompleteChain As Boolean
Introduced in version 9.5.0.44

If True, then adding a private key to the JKS only succeeds if the certificate chain can be completed to the root certificate. A root certificate is either a trusted CA root or a self-signed certificate. If False, then incomplete certificate chains are allowed. The default value is True.

top
VerboseLogging
VerboseLogging As Boolean

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

top
VerifyKeyedDigest
VerifyKeyedDigest As Boolean
Introduced in version 9.5.0.44

If True, then the keystore's keyed digest is required to pass validation (password required) for any of the load methods (such as LoadFile, LoadBinary, or LoadEncoded). If False, then a keystore may be loaded into memory without password validation (if a null or empty string is passed to the load method). The default value of this property is True.

top
Version
Version As String (ReadOnly)

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

Methods

AddPfx
Function AddPfx(ByVal pfx As Pfx, ByVal alias As String, ByVal password As String) As Boolean
Introduced in version 9.5.0.44

Adds the contents of a PFX or PKCS #12 (.p12) to the Java keystore 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.)

This method does not add trusted certificate entries to the JKS.

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.

The UseCertVault method may be called to provide additional certificates for the automatic construction of the certificate chains. If the RequireCompleteChain property is set to True, then this method will fail if any certificate chain is not completed to the root. The TrustedRoots class may be used to provide a source for obtaining trusted CA roots if these are not already present within the PKCS12.

Returns True for success, False for failure.

top
AddPrivateKey
Function AddPrivateKey(ByVal cert As Cert, ByVal alias As String, ByVal password As String) As Boolean
Introduced in version 9.5.0.44

Adds a private key entry to the JKS. Both the private key and certificate chain are obtained from the certificate object that is passed in the 1st argument.

If the alias is empty, then the alias is automatically chosen based on the certificate's information, in the following order of preference:

  1. Certificate's subject common name
  2. Certificate's subject email address
  3. Certificate's serial number

The UseCertVault method may be called to provide additional certificates for the automatic construction of the certificate chains. If the RequireCompleteChain property is set to True, then this method will fail if the certificate chain is not completed to the root. The TrustedRoots class may be used to provide a source for obtaining trusted CA roots.

Returns True for success, False for failure.

top
AddSecretKey
Function AddSecretKey(ByVal encodedKeyBytes As String, ByVal encoding As String, ByVal algorithm As String, ByVal alias As String, ByVal password As String) As Boolean
Introduced in version 9.5.0.66

Adds a secret (symmetric) key entry to the JKS. This adds a symmetric key, which is simply a number of binary bytes (such as 16 bytes for a 128-bit AES key). The encodedKeyBytes provides the actual bytes of the symmetric key, in an encoded string form. The encoding indicates the encoding of encodedKeyBytes (such as "base64", "hex", "base64url", etc.) The algorithm describes the symmetric algorithm, such as "AES". The alias is the password used to seal (encrypt) the key bytes.

Note: The algorithm describes the usage of the encodedKeyBytes. For example, if encodedKeyBytes contains the 16 bytes of a 128-bit AES key, then algorithm should be set to "AES". The actual encryption algorithm used to seal the key within the JCEKS is PBEWithMD5AndTripleDES, which is part of the JCEKS specification.

Returns True for success, False for failure.
