class Crc32 : Digest [final] ¶

This class implements the CRC-32 checksum algorithm. The digest returned is a little-endian 4 byte string.

this(Crc32 crc32) ¶

Create a cloned CRC32

this(uint polynomial = 0xEDB88320U) ¶

Prepare Crc32 to checksum the data with a given polynomial.

Parameters:

polynomial

The magic CRC number to base calculations on. The default compatible with ZIP, PNG, ethernet and others. Note: This default value has poor error correcting properties.

Crc32 update(const(void[]) input) [override] ¶

uint digestSize() [override] ¶

The Crc32 digestSize is 4

ubyte[] binaryDigest(ubyte[] buf = null) [override] ¶

uint crc32Digest() ¶

Returns the Crc32 digest as a uint
