Hash/Shifrlash ko'p hollarda parolni shiflarshda ishlatiladi.
Phpda ma'lumotni shifrlash quyidagicha ishlatiladi.

$uzfor = 'Salom';
echo md5($uzfor);
// Natija: 4be1041e508b1bcadd666d5170a4bfce

Bir marta shifrlangan ma'lumotni dehash qilish mumkin, lekin ikki marta shifrlangan ma'lumotni ochib bo'lmaydi, masalan:

$uzfor = 'Salom';
echo md5(md5($uzfor));
// Natija: ff50b0ddbf587d70bd8dbbec3d867403

Shifrlash turlari ko'p, bularga: base64, md2, md4, md5, sha1, sha256, sha384, sha512, snefru, gost, adler32, crc32, crc32b, whirlpool, ripemd128, ripemd160, ripemd256, ripemd320, tiger128,3, tiger160,3, tiger192,3, tiger128,4, tiger160,4, tiger192,4, haval128,3, haval160,3, haval192,3, haval224,3, haval256,3, haval128,4, haval160,4, haval192,4, haval224,4, haval256,4, haval128,5, haval160,5, haval192,5, haval224,5, haval256,5lar kiradi.

Qanday dehash qiladiDe hash qilish deyarli imkonsiz!
2 daqiqa 44 soniyadan keyin yozdi:
Bitta yo'li, arxivlar katalogidan dehash qilish mumkin. Bu uchun esa anchagina so'zlarning oddiy matni va hashlangan shakli mavjud bo'lishi kerak. Ammo samaradorlik ancha kam. Ommaviy so'zlarni topish oson. Ammo kamnamo so'zlarni topish anchagina qiyin bo'ladi.
