      Deprecated.
      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.
      Parameters:
        `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.
      Returns:
        A PKCS #7 signed data message.
      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.
