Messages are encrypted using AES128 in CBC mode, and signed using a public key.
Messages are encrypted using AES128 in CTS mode, and signed using a public key. For encryption keys or public keys, see [[Keys#Envelope_Files_Keys|Keys]].

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 CTS mode, and signed using a public key. For encryption keys or public keys, see Keys.

Structure[edit | edit source]

Format[edit | edit source]

Fields are little-endian.

Name Offset Size Example Remark
Signature 0x000 4 CC CB 73 51 Four bytes, not an int
Version 0x004 4 00 00 00 00 Only version 0 (zero) exists
Content ID 0x008 4 01 00 00 00 See Content
Unknown 0x00C 4 00 00 00 00 Always 0
Message Size 0x010 8 83 03 00 00 00 00 00 00 Size of the message in bytes.
Unknown 0x018 8 00 00 00 00 00 00 00 00 Always 0
Message IV 0x020 16 IV for encrypted message
Message Hash 0x030 32 SHA256 hash of unencrypted message bytes
File Signature 0x050 256 Verified using public key
Message Data 0x150 Message Size Encrypted message bytes. Encryption key and public key varies with content ID

Content[edit | edit source]

The underlying unencrypted message format varies between different content.
