CRC is a simple command-line utility to compute various CRC values for one or more files.
It supports three CRC algorithms (selected via --mode=<alg>
):
crc64-ecma
uses the ECMA polynomial to compute a 64-bit CRC.crc64-iso
uses the ISO polynomial to compute a 64-bit CRC.crc32
(default) uses the IEEE polynomial to compute a 32-bit CRC. This is equivalent to the crc32
linux binary.If only a single file is specified on the command line, then only the hexadecimal hash is printed. If more than one file is specified, the output will be
<hash><tab><filename>
for each file.
go get github.com/augustoroman/crc
# Compute the default hash (crc32 w/ IEEE polynomial) of one or more files.
crc <file> [<file> ...]
# Compute the crc64 hash with ISO polynomial.
crc --mode=crc64-iso <file> [<file> ...]
# Compute the crc64 hash (with the ECMA polynomial).
crc --mode=crc64-ecma <file> [<file> ...]
