AES128 in CBC mode decode on longer data [libgcrypt]

[Jan Bilek]

Hello Jussi,

We've been able to reproduce all test vectors from 
https://github.com/Cloudera-Intel-QA-Transition/test-cases/wiki/Diceros-Test-Cases 
.

All went well except for AES128 decode in CBC mode. This is strange as 
the same code does very well for AES 192 & 256.

Would you mind if I'll ask you to confirm on following vector?

KEY = 0700d603a1c514e46b6191ba430a3a0c
IV = aad1583cd91365e3bb2f0c3430d065bb
PLAINTEXT = 068b25c7bfb1f8bdd4cfc908f69dffc5ddc726a197f0e5f720f730393279be91
CIPHERTEXT = 
c4dc61d9725967a3020104a9738f23868527ce839aab1752fd8bdb95a82c4d00

Which should be hopefully something like this:

+      { GCRY_CIPHER_AES128,
+ "\x07\x00\xd6\x03\xa1\xc5\x14\xe4\x6b\x61\x91\xba\x43\x0a\x3a\x0c",
+ "\xaa\xd1\x58\x3c\xd9\x13\x65\xe3\xbb\x2f\x0c\x34\x30\xd0\x65\xbb",
+        { { 
"\x06\x8b\x25\xc7\xbf\xb1\xf8\xbd\xd4\xcf\xc9\x08\xf6\x9d\xff\xc5"
+ "\xdd\xc7\x26\xa1\x97\xf0\xe5\xf7\x20\xf7\x30\x39\x32\x79\xbe\x91",
+            32,
+ "\xc4\xdc\x61\xd9\x72\x59\x67\xa3\x02\x01\x04\xa9\x73\x8f\x23\x86"
+ "\x85\x27\xce\x83\x9a\xab\x17\x52\xfd\x8b\xdb\x95\xa8\x2c\x4d\x00" },
+        }
+      },

If you can encode (should do well) and decode the result back.

Thank you,
Jan
