Açıklama

Compile a string for use as the salt argument to crypt().

Bağımsız Değişkenler

prefix
Hashing method. One of the CRYPT_PREFIX_* constant. If null, the best available hashing method will be selected.
count
Controls the processing cost of the hash; the valid range and exact meaning of count depend on the hashing method, but larger numbers correspond to more costly hashes in terms of CPU time and possibly memory usage. If count is 0, a low default cost will be selected.

Dönen Değerler

Returns a string with the setting, or null in case of an error.
