Kernel Crypto API : Message Digest

December 30, 2019 16 min read
The kernel crypto API offers a rich set of cryptographic ciphers as well as other data transformation mechanisms and methods to invoke these. The kernel crypto API refers to all algorithms as “transformations”. Therefore, a cipher handle variable usually has the name “tfm”. Besides cryptographic operations, the kernel crypto API also knows compression transformations and handles them the same way as ciphers.
