Savedata Encryption/Decryption

[Toa of Mirrors]

Is there a way to input an encrypted save and output a decrypted save?

enable handle savedata in crypto mode for encrypted savedata, turn it off for decrypted savedata.

Yeah, but I want to see if I can port any of my old savedata from Birth By Sleep to Final Mix (both of which work on JPCSP by the way), and SED doesn't work for me, so I want to decrypt a preexisting Birth By Sleep PSP gamesave and, if it works, reencrypt it, or resave it decrypted, to load it on my PSP.
