Hi! I hope someone on this newsgroup can help me. I'm developing an extension for Mozilla 1.0, and I need to read and write encrypted data to disk. Only my extension needs (or should be able) to read it. But it should be a strong encryption, because the scores of a student will be recorded and saved for transmit later, and we don't want the user to be able to alter that score.
Since there is a lot of security stuff in the mozilla code already, I thought I could reuse that. But unfortunatly, I don't have a clue where to start. I've tried to search on the mozilla homepage, but I couldn't find an easy to read introduction to crypto. Could someone give me an example of how to encrypt and decrypt a block of bytes? bye, Markus
