Crc32

cometa.cryptography.crc32.crc32(data)[source]

Computes the CRC32 checksum for the given data.

CRC32 (Cyclic Redundancy Check) is used in Cardano for data integrity verification, particularly in Byron-era address encoding.

Parameters:: data (bytes | bytearray) – The data to compute the checksum for.
Returns:: The 32-bit CRC32 checksum.
Return type:: int

Example

>>> crc32(b"Hello, world!")
