How do I change the parameters (algorithm, hash, key-lengh, block-size, IVs, mode-of-operation, key-derivation function etc.) for the encryption being used by Linux built in Full Disk Encryption (System Encryption)?
EDIT : I want to use native Rijndael instead of 'AES' cipher, since using Rijndael allows more options to set instead of AEStandard. Is this somehow possible? E.g. mcrypt (i think) provides native Rijndael cipher (with variable block-size, etc.) instead of AES. Unfortunatelly I cant find a way to use it as full-disk-encrpytion.
This is a solely technical question. No general discussion about reasons 'why not to change' these parameters, please. Pertinent help much appriciated.
