Fast Cross-Platform C/C++ Hashing Library [closed]

Answer 1

zlib has a built-in implementation of a crc32 variant, and is widely ported. =)

Answer 2

Take a look at the plibsys C library: it support MD5, SHA1, SHA-2 (224, 256, 384, 512), SHA-3 (224, 256, 384, 512) and GOST 34.11-94 cryptography hash algorithms. The library is portable and light-weight itself.

Answer 3

Maybe you can use libbeecrypt?

Answer 4

QT seem to implement MD4, MD5 and SHA1

Answer 5

For usual crypto hashes (MD?, SHA? etc.), openssl is the most portable and probably fastest. None of the hashes you mentioned are good for high performance data structures like hash tables. The recommended hash functions for these data structures these days are: FNV, Jenkins and MurmurHash.

Answer 6

Device cross platform? If it means to you what it means to me that means not linux or perhaps operating system independent. I would and did avoid such things as openssl. I went with libtomcrypt. Now as far as speed goes? Well fast, portable, C, chose any two.
