Editing Envelope Files

Envelope files are a general purpose container format for encrypting and signing a message. This format was likely introduced in FW 3.00 (>2.56 <=3.50).

Messages are encrypted using AES128 in CBC mode, and signed using a public key. For encryption keys or public keys, see [[Envelope file/Encryption|Encryption]].

== Format ==

Fields are little-endian.
