Subject: OpenSSL AES strange problem (first block is decrypted wrongly)

Hi,

I am trying to decrypt two blocks of encrypted data using OpenSSL AES
(in CBC mode). Second block is decrypted correctly but first block is
strangely wrong. Any ideas what is going on?. Can someone give it a
shot?

The expected output is
"3f28d3271e76e6809e00fc9670e5ef54dc94ebc3000000000000000000000000".
The attached program decrypts the second block correctly but fails for
the first block.

Cheers,
Dhiru
