As I know, there is block cipher AES in dm-crypt.
When I looked into the documentation of zymkey, there is no block cipher AES.
Do you use the AES software implementation when using the dm-crypt?
How can you control the master key of AES?
I mean that, in normal dm-crypt (luks), the master key is generated from passphrase.
And the software block cipher AES is performed to encrypt all files in raspberry pi.
Is zymkey same?
