[CRYPTO] tcrypt: Add self test for des3_ebe cipher operating in cbc mode
Browse files Browse the repository at this point in the history 
Patch to add checking  of DES3 test vectors using CBC mode.  FIPS-140-2
compliance mandates that any supported mode of operation must include a self
test.  This satisfies that requirement for cbc(des3_ede).  The included test
vector was generated by me using openssl.  Key/IV was generated with the
following command:

	openssl enc -des_ede_cbc -P

input and output values were generated by repeating the string "Too many
secrets" a few times over, truncating it to 128 bytes, and encrypting it with
openssl using the aformentioned key.  Tested successfully by myself
