Crate scrypt[−][src]

This crate implements the Scrypt key derivation function as specified in [1].

If you are not using convinience functions scrypt_check and scrypt_simple it's recommended to disable scrypt default features in your Cargo.toml:

[dependencies]
scrypt = { version = "0.1", default-features = false }

Acknowledgments

This implementation is heavily based on rust-crypto's scrypt module.

Functions

scrypt	The scrypt key derivation function.
scrypt_check	`scrypt_check` compares a password against the result of a previous call to scrypt_simple and returns `Ok(())` if the passed in password hashes to the same value, `Err(CheckError::HashMismatch)` if hashes have different values, and `Err(CheckError::InvalidFormat)` if `hashed_value` has an invalid format.
scrypt_simple	`scrypt_simple` is a helper function that should be sufficient for the majority of cases where an application needs to use Scrypt to hash a password for storage. The result is a String that contains the parameters used as part of its encoding. The `scrypt_check` function may be used on a password to check if it is equal to a hashed value.
