MU Server Tools

MU Client Decryptor

Decrypt a modern MU client's encrypted assets (AESCB02: .bmd.enc / .ozj.enc / .ozt.enc) right in your browser. Recover your AES key straight from your DLL, then decrypt your whole Data folder. Nothing is uploaded.

Decrypt your assets

Recommended

Whole Data folder

Decrypt every .enc in place, no size limit. Chrome / Edge only.

A few files

Drop individual .enc files and download the decrypted results.

Total: 0 Decrypted: 0 Already plain: 0 Failed: 0
Tip: in folder mode, files keep their .enc name but hold plaintext inside. The client reads them via its plaintext fallback, so you don't need to re-encrypt. Test one file in a copy of your client before replacing your live Data.
