The Encryptor module in Fusion currently only supports ASCII Armor encoded files. Armor-encoding bloats file size significantly and is generally not as preferable for SFTP transfer as binary-encoded files as a result.
PRIMARY ASK: Have the Decrypt a PGP message module automatically detect whether the input data is Armor or binary encoded.
SECONDARY ASK: Have the Encrypt a PGP message module to have an advanced option to allow the user to select which mode is preferred.
