Ok, corrected the broken output vector and retested _several_ times. Also added
to test case 4 as requested. Sorry again for the trouble
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
