This is a work in progress, -and still at a very early stage as of this writing.</p> - -<p>The main addition to the stock cryptlib environment is a set of -Hardware Adaption Layer (HAL) implementations that use the Cryptech -FPGA cores.</p> - -<p>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.</p> - -<h2>Current status</h2> - -<p>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:</p> - -<ul> -<li><p>An implementation using the <code>coretest</code> byte-stream protocol -implemented by the <code>core/novena</code> FPGA build.</p></li> -<li><p>An implementation using the simpler interface implemented by the -<code>core/novena_i2c_simple</code> environment.</p></li> -<li><p>An implementation using the <code>coretest</code> byt-stream protocol as -implemented by the <code>test/novena_trng</code> FPGA build. This differs from -the others in that it supports the Cryptech TRNG. Note that neither -this HAL nor this FPGA build supports any cryptographic algorithms.</p></li> -</ul> - -<p>All of these HAL implementations are in the <code>src/</code> directory. See the -<code>GNUmakefile</code> for details on how to select the variant you want.</p> - -<p>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.</p> - -<p>In principal there is no reason why one could not write a HAL which -spoke to a Terasic board, perhaps via the <code>coretest</code> protocol over a -UART, but to date this has not been done.</p> - -<h2>Code import status</h2> - -<p>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.</p> - -<p>Packaging Cryptlib this way has two implications:</p> - -<ul> -<li><p>You may need to <code>apt-get install unzip</code> on your Novena.</p></li> -<li><p>Any changes you might make to Cryptlib itself will be lost when you -run <code>make clean</code>.</p></li> -</ul> - -<h2>Test code</h2> - -<p>The <code>tests/</code> 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.</p> - -<h2>Copyright status</h2> - -<p>Cryptlib itself is copyright by Peter Gutmann. See the Cryptlib web -site for licensing details.</p> - -<p>Code written for the Cryptech project is under the usual Cryptech -BSD-style license.</p> -}}} - -[[RepositoryIndex(format=table,glob=sw/cryptlib)]] - -|| Clone `https://git.cryptech.is/sw/cryptlib.git` || |
