Hi all!

I tried to decrypt input file of size 24B that was not previously encrypted (just some random 24B) using des-cbc. This is command:

openssl des-cbc -d -in input -out output -K 0123456789abcdef -iv 0123456789abcdef -nopad -nosalt

I got some output of size 24B. Then I tried to decrypt same file with different iv:

openssl des-cbc -d -in input -out output1 -K 0123456789abcdef -iv 8578576768789863 -nopad -nosalt

I got file output1 where only first 8 bytes are differ from first 8 bytes of file output, other 16 are identical. Is it normal situation? How it happens from des algorithm point of view?

Thanks for any help in advance.
