Revision history for phkdf

Version 0.1.0.0 (2025-01-20)

• This includes the Version 2 of PHKDF, which is mostly compatible with Version 1 except that the slow extract function has been removed and the end-of-message padding has been tweaked to save a byte when the domain tag is 20 bytes or longer. A simpler slow-extract function much closer to PBKDF2 will eventually be factored out of g3p-hash version 2.

• Saving this byte requires bitstring SHA256 inputs, thus the binding has been moved from cryptohash-sha256 to the new sha256 package. This is a new FFI binding around the core cryptohash implementation that better and more robustly supports the needs of this library.

• The old code in Crypto.PHKDF has been moved to Crypto.PHKDF.V1.Cookbook

Version 0.0.0.0 (2024-03-21)

• The definition of Crypto.PHKDF.Primitives is quite stable.

• Note that Crypto.PHKDF is intended to be more of a cookbook demonstrating how to use and understand PHKDF than anything intended to be deployed. The definition and results, and possibly the interface of phkdfSimple and phkdfHardened will be completely revamped for Version 0.1
