From d729de23e86bbbb28adf6c3ded3651ea4ad8c539 Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Tue, 3 Jun 2008 20:00:16 +1000 Subject: [CRYPTO] tcrypt: Add self test for des3_ebe cipher operating in cbc mode 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.
