CRYPT_EXT_DES - Extended DES-based hash.
Using invalid characters in the salt will cause CRYPT_STD_DES - Standard DES-based hash with a two character saltįrom the alphabet "./0-9A-Za-z".That start with the same eight characters will generate the same result It also only uses theįirst eight characters of string, so longer strings Salt as the first two characters of the output. The standard DES-based crypt() returns the Longest valid salt allowed by the available hashes. PHP sets aĬonstant named CRYPT_SALT_LENGTH which indicates the The hash type is triggered by the salt argument.Īuto-generate either a standard two character (DES) salt, or a twelveĬharacter (MD5), depending on the availability of MD5 crypt().

password_hash() is a simple crypt() wrapper and compatible with existing password hashes. Password_hash() uses a strong hash, generates a strong salt, and applies proper rounds automatically. Make sure to specify a strong enough salt for better security. However, crypt() creates a weak hash without the salt, and raises an E_NOTICE error without it. Prior to PHP 8.0.0, the salt parameter was optional. Hashes created by crypt() can be used with password_verify() isĬompatible with crypt().
