The key used to do the encryption, the Full Volume Encryption Key (FVEK) and/or TWEAK key, is stored in the BitLocker metadata on the protected volume. All clients must use the same algorithm. It is provided for general information only and should not be relied upon as complete or accurate. I'm trying to use web crypto API with IE11 and encrypt/decrypt using AES-256-GCM. First, you will need to generate a pseudo-random string of bytes that you will use as a 256 bit encryption key. createCipher will always generate the same initializ. This algorithm was developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen.
