Breaking change

IExternalSignature interface:

  • getHashAlgorithm is renamed to getDigestAlgorithmName
  • getEncryptionAlgorithm is renamed to getSignatureAlgorithmName

PrivateKeySignature class implements IExternalSignature. So the changes are similar:

  • getHashAlgorithm is renamed to getDigestAlgorithmName
  • getEncryptionAlgorithm is renamed to getSignatureAlgorithmName
  • getSigantureMechanism become private (from public)

PdfPKCS7 class:

  • getHashAlgorithm is renamed to getDigestAlgorithmName
  • getDigestEncryptionAlgorithmOid is renamed to getSignatureMechanismOid
  • getDigestAlgorithm is renamed to getSignatureMechanismName
  • getEncryptionAlgorithm is renamed to getSignatureAlgorithmName
  • setExternalDigest is renamed to setExternalSignatureValue
EncryptionAlgorithms class is renamed to SignatureMechanisms
