Discuz strhash函数 用途不祥
//不知道干啥的function strhash(, = 'DECODE', = '') {
= md5( != '' ? : getglobal('authkey'));
if( == 'DECODE') {
= gzuncompress(base64_decode());
= substr(, 0, -16);
= substr(, -16);
unset();
}
= substr(md5(.substr(, 0, 16)), 4, 8).substr(md5(.substr(, 16, 16)), 18, 8);
if( == 'DECODE') {
return == ? : '';
}
return base64_encode(gzcompress(.));}
