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).
The PS4 requests a number of .env files from Sony servers, they use some form of encryption so I am uncertain as to what they contain.


Messages are encrypted using AES128 in CTS mode, and signed using a public key. For encryption keys or public keys, see [[Envelope Files/Encryption|Encryption]].
Here is a list of the ones I've logged on my PS4:
