OS X SHA512 failure

[andyfleming]

The below script runs fails on OS X:

var crypt = require('crypt3');

var password = 'secret';
var hash = '$6$rounds=1234$56abadac833a5$fQIaUG/da/KqlJc5DzCIym/PL.ZhEdw5VOZsw7mofkm.3aE2rZ/rjDCczymRbj1V3rF6lzJO7DR1WOd2ZnC6O.';

var result = (hash === crypt(password, hash));

console.log(result); // true on ubuntu, false on os x

Specific cases:

• PASSES: Ubuntu 14.04.1 and node v5.4.0
• FAILES: OS X 10.11.1 and node v5.1.0

This probably is because SHA-512 / $6$ feature is a non-standard glibc2 add-on in the crypt() function. I fear there isn't much I can do to fix this except maybe to create an emulation of the whole function.

Hi,

Just to inform that https://www.npmjs.com/package/shacrypt perform functional sha512 & sha256 on OSX :)
