I’ve added some functionality to the PGP Pipeline component to enable it to Sign and Encrypt files.
ASCIIArmorFlag – Writes out file in ASCII or Binary
Extension – Final File’s extension
Operation – Decrypt, pilule Encrypt, and now Sign and Encrypt
Passphrase – Private Key’s password for decrypting and signing
PrivateKeyFile – Absolute path to private key file
PublicKeyFile – Absolute path to public key file.
TempDirectory – Temporary directory used for file processing.
Email me if you could use this.
