My Samsung Android device just stopped working. I still have my SD card, but all data in it is encrypted. Encryption has been performed at the file level, so I have the directory structure and filenames in plain text, but file contents are encrypted.
I remember the key I used to set up encryption, but I need to know what algorithm did Samsung use for encryption and how they generated an encryption key from my passphrase.
Does anyone know if I can recover my data without the original device, using OpenSSL or a similar program?
