# Module crypto::pbkdf2 [−] [src]

This module implements the PBKDF2 Key Derivation Function as specified by http://tools.ietf.org/html/rfc2898.

## Functions

pbkdf2 | Execute the PBKDF2 Key Derivation Function. The Scrypt Key Derivation Function generally provides better security, so, applications that do not have a requirement to use PBKDF2 specifically should consider using that function instead.
pbkdf2_check | pbkdf2_check compares a password against the result of a previous call to pbkdf2_simple and returns true if the passed in password hashes to the same value.
pbkdf2_simple | pbkdf2_simple is a helper function that should be sufficient for the majority of cases where an application needs to use PBKDF2 to hash a password for storage. The result is a String that contains the parameters used as part of its encoding. The pbkdf2_check function may be used on a password to check if it is equal to a hashed value.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
