encrypt data/Crypt/salt
I want to add encryption to my password field using crypt/salt. I need to encrypt the current data as the passwords are not encrypted yet.
I've got a few questions regarding this:
1. how can I encrypt uncrypted data (password field) in mysql for cyrpt?
2. Can these passwords, when encrypted like this, being decrypted with WA crypt/salt?
3. how long has this salt string to be? would 32 signs be ok, like this:
$WA_SECURITY_KEY = "2d66aed7a5328a988f77cbaec59fc047";
? Thanks for any help
