I use a php script that hashes passwords using php’s crypt and uses SHA512, however when I try to check if SHA512 is set I get the above error. Of course I know WHY I get this error.. php is missing some dependency. I just don’t know what that dependency is.
Can anyone please tell me what I need to install (on a Ubuntu server) to be able to use SHA512 in PHP ?
Thanks!
The php docs say that built-in support for SHA-256 and SHA-512 was added in PHP 5.3.2. If you use any earlier versions of PHP, it relies on implementations of those algorithms provided by your system, which apparently yours does not have.
