— Method: pgg-scheme-lookup-key scheme string &optional type

Return keys associated with string. If the optional third argument type is non-nil, it searches from the secret keyrings.

— Method: pgg-scheme-encrypt-region scheme start end recipients &optional sign passphrase

Encrypt the current region between start and end for recipients. If sign is non-nil, do a combined sign and encrypt. If encryption is successful, it returns t, otherwise nil.

— Method: pgg-scheme-encrypt-symmetric-region scheme start end &optional passphrase

Encrypt the current region between start and end using a symmetric cipher and a passphrases. If encryption is successful, it returns t, otherwise nil. This function is currently only implemented for GnuPG.

— Method: pgg-scheme-decrypt-region scheme start end &optional passphrase

Decrypt the current region between start and end. If decryption is successful, it returns t, otherwise nil.

— Method: pgg-scheme-sign-region scheme start end &optional cleartext passphrase

Make the signature from text between start and end. If the optional third argument cleartext is non-nil, it does not create a detached signature. If signing is successful, it returns t, otherwise nil.

— Method: pgg-scheme-verify-region scheme start end &optional signature

Verify the current region between start and end. If the optional third argument signature is non-nil, it is treated as the detached signature of the current region. If the signature is successfully verified, it returns t, otherwise nil.

— Method: pgg-scheme-insert-key scheme

Retrieve the user's public key and insert it as ASCII-armored format. On success, it returns t, otherwise nil.

— Method: pgg-scheme-snarf-keys-region scheme start end

Collect public keys in the current region between start and end, and add them into the user's keyring. On success, it returns t, otherwise nil.
