    Procedures

    adler32 ¶
    Source

    adler32 :: proc "contextless" (data: []u8, seed: u32 = u32(1)) -> u32 {…}

    crc16_ccitt_0x1021 ¶
    Source

    crc16_ccitt_0x1021 :: proc "contextless" (data: []u8, seed: u16 = u16(0)) -> (result: u16) {…}
     

    Compute CRC-16 in the manner of CCITT (ITU-T V.41), using the 0x1021 polynomial. Generator polynomial: x^16 + x^12 + x^5 + 1

    Used in the UDF (DVD *.iso) disk format's Volume Descriptor Tag, and was more historically the ITU-T V.41 CRC-16 used in the XModem protocol, which uses 0xffff as the initial value.

    crc32 ¶
    Source

    crc32 :: proc "contextless" (data: []u8, seed: u32 = u32(0)) -> u32 {…}

    crc64_ecma_182 ¶
    Source

    crc64_ecma_182 :: proc "contextless" (data: []u8, seed: u64 = u64(0)) -> (result: u64) {…}

    crc64_iso_3306 ¶
    Source

    crc64_iso_3306 :: proc "contextless" (data: []u8, seed: u64 = u64(0)) -> u64 {…}
     

    Generator polynomial: x^64 + x^4 + x^3 + x + 1

    crc64_iso_3306_inverse ¶
    Source

    crc64_iso_3306_inverse :: proc "contextless" (data: []u8, seed: u64 = u64(0)) -> u64 {…}

    crc64_xz ¶
    Source

    crc64_xz :: proc "contextless" (data: []u8, seed: u64 = u64(0)) -> u64 {…}
     

    Compute CRC-64 in the manner of xz, using the ECMA-182 polynomial, bit-reversed, with one's complement pre and post processing. Based on Mark Adler's v1.4 implementation in C under the ZLIB license.

    fnv64 :: fnv64_no_a
     

    If you have a choice, prefer fnv64a

    fnv64_no_a ¶
    Source

    fnv64_no_a :: proc "contextless" (data: []u8, seed: u64 = u64(0xcbf29ce484222325)) -> u64 {…}
     

    If you have a choice, prefer fnv64a
