Generating and Validating signed license file

843811Jul 11 2001 — edited May 18 2004

Hello,

We are doing a java-based software licensing framework in which the application starts only after successful validation of the license file.
Are there any tools in JAVA that can generate a signed license file? There are tools (like javakey) to generate keys and certificates and for jar files - but are there any for signing a text file i.e. a license file in my case? Also can anyone tell me what classes are present in JAVA to validate the signature of a file?
Sun has reference implementations of the necessary code as part of Java Cryptography Extensions (JCE) - but that didn't help me much.

Can ayone help me, please? Thank you.

Andy
