Richard, I’m talking about using the LC encrypt command, with aes-256 encryption. I’m trying to figure out how the “salt” works, because my php code sends me a warning that I am not using a salt, or IV to encrypt the sql query. I bought Andre Garza’s database software and have modified it pretty extensively. But, I’ve use his encryption implementation. His code doesn’t use a salt in his encryption implementation. So, I’m trying to get some info on how to implement the salt, and I haven’t had much luck with google. It seems to be one of those things where the experts are speaking a different language, one I don’t understand. Perhaps it’s so trivial that I’m missing the mark utterly.
A few lines of code that shows how to encrypt, then decrypt a string, with aes-256 and a salt, would solve my problem. Also, I think the responses so far have given me enough hints so when I get back to my computer in a week, I can trial and error figure it out. Thanks for chiming in. I’ll post some code when I figure it out, unless somebody does it first.
