title: Hash password and return string with special characters
body: <p>I am trying to use a hashing algorithm that is really strong and outputs special characters in the encoded string in PHP. Currently I am using hash_pbkdf2 which I understand to be the most secure form of hashing at the moment but it doesn't output a string with special characters only uppercase and lowercase. Is there any way to modify it to do such or is there another algorithm that would work better? Maybe if I combined this with another encryption algorithm which would then take the output of the hash_pbkdf2 and encrypt it to something with special characters as well?</p>
