var_expand_crypt plugin ======================= This plugins provides generic encrypt/decrypt facility for var_expand. It requires functional lib-dcrypt backend. For dovecot-auth process this plugin is automatically usable. Syntax ------ ---%<------------------------------------------------------------------------- args=encrypted_value=%{encrypt;key=value,iv=value,noiv=yes,algo=algorithm,format=base64|hex:field} args=decrypted_value=%{decrypt;key=value,iv=value,noiv=yes,algo=algorithm,format=base64|hex:field} ---%<------------------------------------------------------------------------- * key - hex-encoded value * iv - hex-encoded value * noiv - whether iv is included in return value * algo - algorithm name (defaults to aes-256-cbc) * format - return format decrypt expects input in base64 or hex format. NOTE: It is usually best to leave iv management to dovecot, and not use iv and noiv options at all. Return formats -------------- Without noiv encrypt returns iv$encrypted$. With noiv, just encrypted data is returned. Field(s) are encoded using format. key and iv must be the length required by the given algorithm. Example ------- ---%<------------------------------------------------------------------------- %{encrypt;key=f1f2f3f4f5f6f7f8f1f2f3f4f5f6f7f8f1f2f3f4f5f6f7f8f1f2f3f4f5f6f7f8:password} = 93736a0f910df27f89210e096e1d639a$966c2b4f3e7487f6acdb836f8d1dc3e0$ %{decrypt;key=f1f2f3f4f5f6f7f8f1f2f3f4f5f6f7f8f1f2f3f4f5f6f7f8f1f2f3f4f5f6f7f8:encrypted} = pass ---%<------------------------------------------------------------------------- (This file was created from the wiki on 2019-02-05 04:42)
