WebIn this case, the key is actually REDRYDER\0\0\0\0\0\0\0\0 where the \0 are null bytes. The option -K lets you pass a key, in hexadecimal. If you pass fewer bytes than the key size, OpenSSL completes with null bytes. So to pass the key REDRYDER\0\0\0\0\0\0\0\0, you can pass $ (echo REDRYDER od -An -tx1 tr -d ' ') which is 5245445259444552. 1 Answer Sorted by: 0 As far as warnings are concerned, as mentioned in the comment too, they can be resolved by using the right length for key and iv strings.
