pgg: Back end methods

 
 4.2 Back end methods
 ====================
 
 In each back end, these methods must be present.  The output of these
 methods is stored in special buffers (Getting output), so that
 these methods must tell the status of the execution.
 
  -- 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’.
