Here are some notes about various things I should/could/might do. If you're
interested in working on something here (or something else!), drop me an email
and we can coordinate efforts.

* Algorithms / Related
  - HAS-V hash function (mostly done, but not quite)
  - MACs: UMAC16, UMAC32
  - Block ciphers: MARS, Crypton v1.0, Rainbow (all partially done)
  - Constructions:
      + Cascade Block Cipher
      + Cascade Block Cipher with Stream Cipher [B2(S(B1(x)))]
      + Davies-Meyer or other block cipher based hashes (see BRS paper)
  - Support for crypto hardware
  - New PK algorithms: ECDSA, ?
  - Better entropy estimation
  - PGP CFB block cipher mode

* Major Optimizations
  - BigInt and the related functions could always use more work; there are a
    lot of (fairly) easy optimizations that haven't been done yet, including:
      - Addition chains in FixedExponent_Exp
      - Asymmetric Karatsuba multiplication
  - Assembler implementations of the very low level MPI functions (mp_core.cpp,
    mp_misc.cpp, mp_smul.cpp). Particularly x86, x86-64, SPARC, PowerPC, and
    Alpha would be nice.

* New Interfaces / Protocols
  - SSL/TLS: underway, in the Ajisai library
  - CMS (S/MIME), PGP, SSH
  - NIST's PKAPI

* Modules
  - EntropySources
      BeOS: get_next_{team,thread}_info, get_system_info [done, but untested]
        - There are other sources that can be used (current mouse position,
          screen contents, etc) that would probably help
      VMS: I haven't the slightest idea
      MacOS 8/9: No clue
  - Compression: Zip, Gzip
  - Dynamic Algorithm Loader
     - Maybe, (maybe, maybe) integrate it with the stuff in algolist.cpp
       so it can do automatic lookup. I'm rather skeptical of this approach
       but it is a possiblity.
  - Module for the SPARCv9 RDTICK (is there a similiar instruction on PPC too?)
  - Bzip2 and Zlib modules don't clear or lock their memory. This should
    be pretty easy to fix.

* Configure / Build System
  - Support for new OSes: Hurd, QNX, Plan 9, OS/2, VMS, MacOS 8/9
  - Fix the known bugs/deficiencies in the system:
      + Support precision down to the submodel level for system reqs in
        modules; RDTSC doesn't work on an 80486, and we'll take a SIGILL
