Introduction

- -

This is a port of Peter Gutmann's -cryptlib package -to the Cryptech project's environment. This is a work in progress, -and still at a very early stage as of this writing.

- -

The main addition to the stock cryptlib environment is a set of -Hardware Adaption Layer (HAL) implementations that use the Cryptech -FPGA cores.

- -

While we expect to be making more significant use of cryptlib in the -future, the main purposes of this code at the moment are -proof-of-concept and connecting the Cryptech cores to a more complete -cryptographic programming environment for testing and development -purposes.

- -

Current status

- -

At present, the Cryptech HAL code runs only on the Novena PVT1. There -are three variants of the HAL, all using the I2C bus, but speaking -different protocols:

- - - -

All of these HAL implementations are in the src/ directory. See the -GNUmakefile for details on how to select the variant you want.

- -

At present, the only relevant Cryptech cores are the TRNG and several -digest algorithms. The current HAL uses the SHA-1, SHA-256, and -SHA-512 cores to implement the SHA-1, SHA-256, SHA-384, and SHA-512 -digests. SHA-512/224 and SHA-512/256 are not supported.

- -

In principal there is no reason why one could not write a HAL which -spoke to a Terasic board, perhaps via the coretest protocol over a -UART, but to date this has not been done.

- -

Code import status

- -

Cryptlib itself is present in the repository in the form of a verbatim -copy of the Cryptlib 3.4.2 distribution zipfile, which the top-level -makefile unpacks while building. This has proven simpler to work with -than importing the entire Cryptlib distribution into a vendor branch.

- -

Packaging Cryptlib this way has two implications:

- - - -

Test code

- -

The tests/ directory contains a few test scripts, written in Python, -using the standard Cryptlib Python bindings. The Cryptlib Python -environment is a fairly literaly translation of the Cryptlib C -environment, so portions of it will be a bit, um, surprising to Python -programmers, but the basic functionality works. Note that it's normal -for test scripts to fail when the functionality they're testing isn't -loaded on the FPGA.

- -

Copyright status

- -

Cryptlib itself is copyright by Peter Gutmann. See the Cryptlib web -site for licensing details.

- -

Code written for the Cryptech project is under the usual Cryptech -BSD-style license.
