Are you printing out your byte arrays using "toString"?
This does not print the contents of your byte arrays in
the form you wanted (or expected), but prints the unsigned hexadecimal
representation of the hashcode of your objects.

Please use the "toHexString" utility (included in API_users_guide.html)
to print the contents of your input/output byte arrays in
hexadecimal format. Then you'll notice that everything works fine.

See above.
