computeSignature

protected byte[] computeSignature(byte[] content,
 PrivateKey certificatePrivateKey,
 TlsConstants.SignatureScheme signatureScheme,
 boolean client)
                           throws ErrorAlert

Compute the signature used in certificate verify message to proof possession of private key.

Parameters:

content - the content to be signed (transcript hash)

certificatePrivateKey - the private key associated with the certificate

signatureScheme -

client - whether the signature must be computed

Returns:

Throws:

ErrorAlert

getSignatureAlgorithm

protected SignatureAlgorithm getSignatureAlgorithm(TlsConstants.SignatureScheme signatureScheme)
                                            throws HandshakeFailureAlert

Returns the signature algorithm implementing the given signature scheme.

Parameters:

signatureScheme -

Returns:

the signature algorithm, never null

Throws:

HandshakeFailureAlert - when the scheme is not supported (i.e. no factory provides an implementation)
