gzip.crc: Extract the CRC (32 bit hash) of a gzip file
Description
Reads the crc from a gzip file, assuming it is the last 4 bytes
of the file. First checks for a valid gzip magic number at the start of the
file.
Usage
gzip.crc(f)
Value
hexadecimal formatted
Arguments
f
Path to a gzip file
Details
CRC32 is not a strong hash like SHA1 or even MD5, but it does
provide a basic hash of the uncompressed contents of the gzip file.
NB CRCs are stored in little endian byte order regardless of platform.
