Subject: Writing Asynchronous Block Ciphers


I would like to know if anyone has a tutorial/document link in writing
a CRYPTO_ALG_TYPE_ABLKCIPHER crypto device driver? I am looking at
drivers/cipher/mv_cesa.c but there are lots of things going on which
are hardware context related. I would like to know what the minimum
requirements for an asynchronous block cipher drivers are before I
hand over (DMA) the collected data to my encryption hardware.

Thanks in advance for your help!

Kind Regards,
