![]() ![]() The default number of rounds is 5000, there is a minimum of 1000 and a maximum of 999,999,999. If the salt string starts with "rounds=$", the numeric value of N is used to indicate how many times the hashing loop should be executed, much like the cost parameter on Blowfish. - SHA-512 hash with a 16 character salt starting with $6$.Any selection of N outside this range will be truncated to the nearest limit. - SHA-256 hash with a 16 character salt starting with $5$.Values outside this range will cause the function to fail. The "$" parameter is the base-2 logarithm of the iteration count for the underlying Blowfish-bashed hashing algorithmeter and must be in range 04-31. Using characters outside of the alphabet will cause this function to return a zero-length string. - Blowfish hashing with a salt starting with $2a$, $2x$, or $2y$, a two digit cost parameters "$", and 22 characters from the alphabet "./0-9A-Za-z".- MD5 hashing with a 12 character salt starting with $1$.Using invalid characters in the salt will cause the function to fail. The values 0 to 63 are encoded as "./0-9A-Za-z". These are encoded as printable characters, 6 bits per character, least significant character first. - Extended DES-based hash with a nine character salt consisting of an underscore followed by 4 bytes of iteration count and 4 bytes of salt.Using invalid characters in the salt will cause this function to fail. - Standard DES-based hash with two character salt from the alphabet "./0-9A-Za-z".The value of these constants are set by PHP when it is installed. There are some constants that are used together with the crypt() function. Make sure to specify a strong enough salt for better security. PHP checks what algorithmsĪre available and what algorithms to use when it is installed. This function behaves different on different operating systems. The crypt() function returns a hashed string using DES, Blowfish, or MD5 algorithms.
