Interface SaltedAuthenticationInfo

All Superinterfaces:
AuthenticationInfo, Serializable
All Known Implementing Classes:
SimpleAccount, SimpleAuthenticationInfo

public interface SaltedAuthenticationInfo
extends AuthenticationInfo

Interface representing account information that may use a salt when hashing credentials. This interface exists primarily to support environments that hash user credentials (e.g. passwords).

Salts should typically be generated from a secure pseudo-random number generator so they are effectively impossible to guess. The salt value should be safely stored along side the account information to ensure it is maintained along with the account's credentials.

This interface exists as a way for Shiro to acquire that salt so it can correctly perform credentials matching during login attempts. See the HashedCredentialsMatcher JavaDoc for more information on hashing credentials with salts.
