Re: Decrypt oracle data with java

Unfortunately, you can't do what you want. The obfuscation toolkit puts in prepends a header to the data to prevent double encryption (U.S. government requirement). So, direct decryption will fail.

The only way to do it would be to have the Java code call the obfuscation toolkit.
