WebMar 14, 2011 · Solution 1. You are providing it with 2125 bytes, which is not a multiple of 8. When you are ENcrypting, padding is used to make your input up to a multiple of the block size (so the last input block is full size). When you are DEcrypting, you need to decrypt full blocks, then strip off or ignore any padding in the decrypted output.
