For more information on SHA1, see this Wikipedia link.
$str: A string
String: SHA1 hash (40 character hexadecimal number) of str
<? // Name this example and call it with this: sha1.cgi?key=secretkey // SHA1 hash value for "secretkey": $hash="9885F8AF04289135DF259E34BD22D17FE45EA81E"; if (sha1($_GET['key']) == $hash) { print("hashes match!"); } ?>
md5() - Calculate the MD5 hash of a string
md5_file() - Calculate the MD5 hash of a file
