minicrypt

------------

Base encodings: base91, base32

Ascii table dumper: ascii

------------

Statically linked binaries, linux 64bit, sizes: between 1kB and 5kB: ./bin
Part of "minicore" - Aiming for a unix system with 64kB.

sha1 is the reference implementation, I just replaced the loop unrolls with loops, and a few other size optimizations. Got this down from 8kB to 1kB.

Since the whole bin directory is less than 32kB, I made a tarball, containing this readme, the binaries, and accompanying licenses. minicrypt.tgz.

The executables just read from stdin, and write to stdout.

Possible arguments are printed with "-h" (if any).

The hashes are based on the reference implementations, slightly modified to optimize for size. (stripped loop unrolls, etc)

Replaced several 32bit instruction with 64bit, and inserted bswap/ror/rol instructions, where possible.

amd64 only. (Intel and AMD x64)

The full sources, which do not depend on any library, also not libc, are in the folders, and named blake3sum.src.c, ...

These are generated with minimake, part of minilib. (Another project of mine)

The sources here are quite untidy. My fault. On the other hand, the disassembly of the binaries should be readable. If you're in doubt, I stripped them heavily to save space, even the section headers are stripped. Therefore you'd need something like ndisasm to get the disassembly. The entry function is somewhere around 0xc2 (pop rdi).

I hand the cleanup of the sources to the compiler, with best wishes.

The following licenses apply to the unmodified implementations.

• md6: MIT
• blake3: CC0, or alternatively Apache License 2.0
• blake2: CC0, Apache 2.0, or Openssl
• sha512: BSD 2-clause
• base91: BSD 3-clause
• sha1: Steve Reid, Public Domain

base32, ascii, hex entered by me. BSD 3clause. (sources and binaries)
minilib comes with other License terms. (BSD like, with attribution), but I don't apply those terms to the binaries or sources here.

somehow - I guess, I'm going to enlarge the 64kB core to 128 kB. Or I'll need to have a multicall binary. I don't like that, I don't like bloating software either, I'm screwed

Maybe, I just shouldn't count "nonstandard" tools - md6, blake3!?

misc, December 2022.

Currently, I'm thinking about an abstract interface.
Did some experiments with oop in c. It is a so really good idea.
Like the size optimization of hashes.

The openbsd fish did some diet.
