I mean, crypt()’s return is always different.
So how do websites like 4chan do to give a permanent tripcode to a password?
Are they stored in a database?

You pass the salt to
crypt()as the second argument. This causes the output to use that salt instead of generating one on the fly.The salt being randomly generated is why
crypt("something")returns different results each time. If I runcrypt("something", "ab"), it’ll be identical every time. I don’t have PHP here to check what the value is, though.Wikipedia has an article about Tripcodes.
