Cryptlib is supplied as source code for AMX, BeOS, ChorusOS, DOS, DOS32, eCOS, µC/OS-II, embedded Linux, FreeRTOS/OpenRTOS, IBM MVS, µITRON, Macintosh/OS X, OS/2, PalmOS, RTEMS, Tandem, ThreadX, a variety of Unix versions (including AIX, Digital Unix, DGUX, FreeBSD/NetBSD/OpenBSD, HP-UX, IRIX, Linux, MP-RAS, OSF/1, QNX, SCO/UnixWare, Solaris, SunOS, Ultrix, and UTS4), uClinux, VM/CMS, VxWorks, Windows 3.x, Windows 95/98/ME, Windows CE/PocketPC/SmartPhone, Windows NT/2000/XP/Vista/Windows 7 (32- and 64-bit versions), VDK, and Xilinx XMK. cryptlib’s highly portable nature means that it is also being used in a variety of custom embedded system environments.
I've recently needed a small library to do some hashing. After lots of searching, I found this little one : https://create.stephan-brumme.com/hash-library/ . Its a tiny single-headered library (or bunch of standalone implementations really) that one can use. it supports sha1,sha256, sha3, etc. Just include the header you need and you are done.
There is also s2n: a C99 implementation of the TLS/SSL protocols that is designed to be simple, small, fast, and with security as a priority. It is released and licensed under the Apache License 2.0.

It's not free for commercial use, though.
我最近需要一个小型库来进行一些哈希处理。
经过大量搜索，我发现了这个小东西：https://create.stephan-brumme。 com/hash-library/ .
它是一个可以使用的小型单头库（或者实际上是一堆独立的实现）。支持sha1、sha256、sha3等
只需包含您需要的标题即可完成。

还有 s2n：TLS/SSL 协议的 C99 实现，设计简单、小型、快速且以安全为优先考虑。它根据 Apache License 2.0 发布并获得许可。
s2n 哈希函数。
