=== Notes ===

*'<PSN_ACCOUNT_ID>' is a unique ID comprised of 16 hexadecimal characters, and doesn't change for a given PSN Account(this isn't just used with PSV, it's also used with PSP)

*".psvimg", ".psvmd" are encrypted.

*".psvmd" files have a fixed size of 0xC0 bytes.

*"license.psvimg" files have a fixed size of 0xE40 bytes.

*"savedata.psvinf" are used only with PSV saves, and have a fixed size of 0x8 bytes. This won't change for a given PSN Account, as it contains the <PSN_ACCOUNT_ID> in hexadecimal(big endian relative to the <PSN_ACCOUNT_ID>).

*The PS Vita System backup <BACKUP_DIRECTORY> name is structured in the format "YYYYMMDDHHMM-NUM". So the first PS Vita system backup on the 23rd of July 2014 at 6:30PM would have a directory name of "201407231830-01". If a user managed to make a second backup in the same minute the directory name of the backup would be "201407231830-02". The "<BACKUP_NAME>" found in "<BACKUP_NAME>.psvimg" and "<BACKUP_NAME>.psvmd" files are the same as the <BACKUP_DIRECTORY> name of the directory they are contained in.

*Saves Contained in the "/PSAVEDATA/<PSN_ACCOUNT_ID>/" folder, are of the same format as PSP saves as they existed on the PSP. So original PSP saves can be transferred to the Vita by placing them in this folder. Restrictions on copying PSP saves to the PSVita vary depending on the CMA version and PSVita version.

==Decyption==
