@Deprecated(since="9", forRemoval=true) public abstract class ContentSigner {
Generates a PKCS #7 signed data message. This method is used when the signature has already been generated. The signature, the signer's details, and optionally a signature timestamp and the content that was signed, are all packaged into a signed data message.
Params:
  • parameters – The non-null input parameters.
  • omitContent – true if the content should be omitted from the signed data message. Otherwise the content is included.
  • applyTimestamp – true if the signature should be timestamped. Otherwise timestamping is not performed.
Throws:
  • NoSuchAlgorithmException – The exception is thrown if the signature algorithm is unrecognised.
  • CertificateException – The exception is thrown if an error occurs while processing the signer's certificate or the TSA's certificate.
  • IOException – The exception is thrown if an error occurs while generating the signature timestamp or while generating the signed data message.
  • NullPointerException – The exception is thrown if parameters is null.
Returns:A PKCS #7 signed data message.
