It returns the hash that is currently 60 character long, however, as new and stronger algorithms will be added to PHP, the length of the hash may increase.
It is therefore recommended to allocate characters for the column that may be used to store the hash in database. It returns true if the password and hash match, or false otherwise. PHP is a server-side scripting language designed specifically for web development.

Scott Arciszewski Rogue He doesn't want a hash, he wants symmetric encryption like AES , he just doesn't know what it's called.
And now he does : — Patashu. A key must be kept secret. A salt can be public without harming security as long as everyone's salt is different , and it is a term used in hashing passwords. You need a Salt private key , a public key an an encryption algorithm like AES wpy. CristianFlorea The author of that blog post uses terms that simply do not make the slightest bit of sense in the context of symmetric encryption.
There is no public key with AES, nor is there a salt. There is a single key; it must be kept secret. In some modes of operation there is an IV that need not be secret, but an IV is not a salt depending on mode, it can have quite different requirements and need not be secret, while the actual encryption key absolutely cannot be public.

Other Design Considerations: Do not compress anything ever. Ciphertext is not compressible; compressing plaintext before encryption can lead to information leaks e. Avoid them if possible. Encryption Key Management If you're tempted to use a "password", stop right now.
First, generate a random key and store it in a constant. Your encryption key will be comically broken. Improve this answer.

Thanks — Andrew. Version 1. Version 2. DO NOT use version 2 before it's released. I really liked the article you provide: paragonie. Show 4 more comments.

This isn't a secure answer. ECB mode shouldn't be used. If you want a "simple and clear answer", just use a library. ScottArciszewski, yes I admit I've spoken too quickly while looking for some simple code. It all depends on the use case! There are cases when this is perfectly FINE.
For a scenario like this, it's a perfect solution, for security it's a no go! Show 11 more comments. Ramesh, this is because you're getting the raw encrypted data.
