1+
Generic hashing framework for PHP
2+
3+
Simplest usages:
4+
5+
$digest = hash($algoname, $message);
6+
$digest = hash_file($algoname, $filename);
7+
8+
Examples:
9+
10+
$digest = hash('md5', 'The quick brown fox jumped over the lazy dog.');
11+
12+
Feeder usage:
13+
14+
$context = hash_init($algoname);
15+
hash_update($context, $message);
16+
$digest = hash_final($context);
17+
18+
hash(), hash_file(), and hash_final() each support an optional boolean parameter $raw_output which behaves in the same
19+
manner as sha1()'s optional parameter.
