I am creating an MD5 Message Authentication Code to exchange with a third-party application. I need to get the MD5 token for the url string I pass to them. When I use JDK 1.4.2.01 the third-party accepts my security token. However; when I use JDK 1.3.1.09 and the optional JCE 1.2.2, the token is different for the same string, and gets rejected by the third-party.
Here is my 1.4.2 code:
Here is my 1.3.1 code
The byte array produced by the following line: byte digest = mac.doFinal(dataBytes); is apparantly incorrect with 1.3.1, but okay with 1.4.2. Can anyone help me with this?
