MD5 is a hashing algorithm so it won't work as you will never get the original password back. But anyhow: If you encrypt your database password and someone gets access to your CI files, he will see the config, and how it is encrypted, what the password is (as you have to decrypt it...) so you won't gain any advantages with this approach.

md5 will always give the same output for the same input, so if you upload the same file twice, then yes, you have already used that hash. If you just want random names, then you don't even need to use MD5 and could just dynamically create a random string everytime a file is uploaded (a, b, c, etc to z, then aa, ab, ac, etc).

Setting your encryption_key ¶. An encryption key is a piece of information that controls the cryptographic process and permits a plain-text string to be encrypted, and afterwards - decrypted. It is the secret "ingredient" in the whole process that allows you to be the only one who is able to decrypt data that you've decided to hide from the eyes of the public.
