Whats the best way to encrypt passwords in php programming?

Question

was thinking and searching about this topic all day I am just curious, If you know whats the best way to crypt information and still be able to decrypt them later own safely Please let me know And wouldn't other people be able to decrypt data just like I did ?

Answer 1

There are two algorithms for encryption md5 and sha but i think md5 is a good way to ecnrypt a password in php

Answer 2

One of the common ways is to save the password as an MD5 hash. When the user submits their password you convert it to MD5 and compare it to the MD5 you have stored. It cannot be decrypted (for the most part) which is a good thing. You don't want to be able to see your user's passwords which is more secure.

Answer 3

The SHA1 hash is the better hash than the MD5 since it have less number of collisions. So it is more safer than MD5 hash. If you need more protection you can use a salt (randomly generated string) along with SHA1 hash along with SHA1 hash (I have used this method to my client websites). You can use PHP sha1() function

if you want to get the SHA1 hash of a password
