WebThe hash length in bytes is included to prevent an accident where the hash gets truncated. For instance, if the hash were stored in a database column that wasn't big enough, and the database was configured to truncate it, the result when the hash gets read back would be an easy-to-break hash, since the PBKDF2 output is right at the end.

Pbkdf2 is a password-based key derivation function that uses a password, a variable-length salt and an iteration count and applies a pseudorandom function to these to produce a key. The original implementation used SHA-1 as the pseudorandom function, but this version uses HMAC-SHA-512, the default, or HMAC-SHA-256. pictionary air app download pc
