Classes

ChecksumAdler32

Adler-32 checksum algorithm implementation, compatible with the zlib standard (RFC 1950). Produces a 32-bit checksum by maintaining two running sums over the input bytes.

ChecksumCRC16

CRC-16-CCITT checksum algorithm implementation using the generator polynomial x^16 + x^12 + x^5 + 1 (hex: 0x1021). Produces a 16-bit cyclic redundancy check value suitable for protocol and packet integrity verification.

ChecksumCRC32

CRC-32 checksum algorithm implementation using the standard IEEE 802.3 generator polynomial. Produces the same 32-bit result as the CRC used in Ethernet, GZip, ZIP, PNG, and many other widespread formats.

ChecksumFletcher32

Fletcher-32 checksum algorithm implementation. Produces a 32-bit checksum by maintaining two running sums over 16-bit words derived from the input data, using a modulus of 65535 (0xFFFF).

ChecksumXXHash32

xxHash32 checksum algorithm implementation, providing extremely fast non-cryptographic 32-bit hashing. Based on the xxHash specification by Yann Collet (BSD 2-Clause License).

ChecksumXXHash64

xxHash64 checksum algorithm implementation, providing extremely fast non-cryptographic 64-bit hashing. Based on the xxHash specification by Yann Collet (BSD 2-Clause License).
