Modifier and Type	Interface and Description
static class	LongPasswordStrategy.BaseLongPasswordStrategy Default base implementation
static class	LongPasswordStrategy.PassThroughStrategy A simple strategy that just returns the provided password without changing it.
static class	LongPasswordStrategy.Sha512DerivationStrategy Will use sha512 to hash given password to generate fixed 64 byte length hash value
static class	LongPasswordStrategy.StrictMaxPasswordLengthStrategy This strategy will always throw an exception to force passwords under the max length
static class	LongPasswordStrategy.TruncateStrategy Truncates the password the max possible length.

Method Summary

Method Detail

derive

byte[] derive(byte[] rawPassword)

Derives (hashes, shortens, etc) the given password to a desired max length.

Parameters:

rawPassword - to check and derive

Returns:

the derived (shortened) password, or the same reference if short enough
