sra at hactrn.net pushed a change to branch master
in repository user/sra/libhal.

      from  e1029f9   This time for sure, Rocky!
       new  9cca190   Add hal_modexp(), since the protocol is a bit complex.  Rewrite test-rsa to use hal_modexp(), and generate a new set of test keys without the whacky padding, since hal_modexp() now handles that.
       new  5d21abb   Operand lengths weren't including bug-workaround padding.
       new  5f152f5   First cut at RSA decryption/signature using the Chinese Remainder Theorem.  Not yet tested, and given the number of moving parts I would be astonished if this version actually worked, but it does compile. Added some timing code to tests/test-rsa.c so we can see whether this is doing anything useful once it does work.
       new  ab7d78b   Build issues on Novena.
       new  8934e10   Debug modexp_fp() buffer handling.  Add basic timing report. Compensate for PyCrypto's weird inversion of p and q when calculating CRT coefficients, and add key the key components PyCrypto doesn't bother pre-calculating to our test data.
       new  7a89eaa   Refactor key loading code.
       new  e6e4a9a   RSA key generation.  Compiles, not (yet) tested otherwise.
       new  ab5a876   RSA key generation and DER support.
       new  35733aa   Debug RSA key generation.
       new  5e4fc53   Refactor CRT code into public API.
       new  8bf2dc8   Add RSA blinding.
       new  3e679aa   Add round-trip test for DER I/O code.
       new  30e8216   Helps to set the return value when reading a key, doh.
       new  a615b13   Supply public exponent as bigendian byte string rather than unsigned long, since that's the form we'll need for PKCS #11.
       new  1a719b0   Add replacement for fp_exptmod() using our ModExp core, so we don't drag in all of TFM's Montgomery just to support the Miller-Rabin test.
       new  79d3c33   Add temporary workaround to let us use software ModExp when we're testing other code and don't want to wait for the as-yet-unoptimized FPGA ModExp core.
       new  aaec57f   Add README.md.
