Hi developers,
I find a bug of aes-128-cfb1: If key is "2b7e151628aed2a6abf7158809cf4f3c" , iv
is "000102030405060708090a0b0c0d0e0f", plain-text is "a" or "abc", aes-128-cfb1
can not encrypt/decrypt correctly. The following is the log file. We can see
that decryption result is different from original plain-text.

The bug at least exists in openssl-0.9.7m, openssl-0.9.7l and openssl-0.9.8b.I
do the test on following platform:openssl-0.9.7m + HP-UX 11.23 + Itanium
CPUopenssl-0.9.7m + HP-UX 11.23 + PA-RISC CPUopenssl-0.9.7l + HP-UX 11.11 +
PA-RISC CPUopenssl-0.9.8b + Redhat Enterprise Linux 5 + x86 CPU
Would you please study this bug?
