It’s completely out of line with […] A message is encrypted with k1 first, then decrypted with k2 and encrypted again with k3. Your code was fine except for the Base 64 encoding bit (which you mentioned was a test), the reason the output may not have made sense is that you were displaying a raw byte array (doing toString() on a byte array returns its internal Java reference, not the String representation of the contents). This question needs to be more focused. @AdrianHope-Bailie That advice is wrong as MD5 only outputs 16 bytes, so the rest would be filled with zero's.
