Method Detail

getCertificate

public Certificate getCertificate()

Description copied from interface: TlsCredentials

Return the certificate structure representing our identity.

Specified by:

getCertificate in interface TlsCredentials

Returns:

our certificate structure.

generateRawSignature

public byte[] generateRawSignature(byte[] hash)
                            throws java.io.IOException

Description copied from interface: TlsCredentialedSigner

Generate a signature against the passed in hash.

Specified by:

generateRawSignature in interface TlsCredentialedSigner

Parameters:

hash - a message digest calculated across the message the signature is to apply to.

Returns:

an encoded signature.

Throws:

java.io.IOException - if the hash cannot be processed, or there is an issue with the private credentials.

getSignatureAndHashAlgorithm

public SignatureAndHashAlgorithm getSignatureAndHashAlgorithm()

Description copied from interface: TlsCredentialedSigner

Return the algorithm IDs for the signature algorithm and the associated hash it uses.

Specified by:

getSignatureAndHashAlgorithm in interface TlsCredentialedSigner

Returns:

the full algorithm details for the signature.

getStreamSigner

public TlsStreamSigner getStreamSigner()
                                throws java.io.IOException

Specified by:

getStreamSigner in interface TlsCredentialedSigner
