What is a blowfish in PHP?

Question

I'm trying to do a login password encryption using PHP and MSQLI and someone suggested using blowfish. Any oversimplified answer would be great thanks.

Answer 1

Blowfish is encryption standard(coding in another language) , it uses hashing i.e converting a input to output which can't be retrieved back . Hashing is generally used to transmit patterns of bit (usually hex) which are highly secure as it's unpredictable.

Answer 2

Blowfish is an encryption algorithm. It's old though and not the most secure cipher. I recommend AES-256, or Twofish, which is the successor to blowfish.
