libscrc is a library for calculating CRC3 CRC4 CRC5 CRC6 CRC7 CRC8 CRC10 CRC11 CRC12 CRC15 CRC16 CRC24 CRC30 CRC31 CRC32 CRC64 CRC82

📚 Provides a handy way to hash data using Adler32, CRC (8-bit to 82-bit, and customizable without bit restriction), MD5, SHA-1 and SHA-2 (256-bit, 384-bit and 512-bit), including HMAC keyed hashing for some types. Functions for encrypting and decrypting data with Rijndael (128-bit, 192-bit and 256-bit) are also offered
