CRC-64

Simple cross-platform command-line tool for computing CRC-64 (ECMA-182) checksums.

Generator polynomial: 0x42F0E1EBA9EA3693

Synopsis:
   crc64.exe [OPTIONS] [<file_1> [<file_2> ... <file_n>]]

Options:
   -h --help --version  Show help screen / show version information
   -b --binary          Output digest in binary format (default is hex-string)
   -d --decimal         Output digest in decimal string format
   -u --upper-case      Print digest as upper-case (default is lower-case)
   -p --no-padding      Print digest *without* any leading zeros
   -s --silent          Suppress error messages
   -e --ignore-errors   Ignore I/O errors and proceeed with the next file
   -f --no-flush        Do *not* flush output stream after each file
   -z --init-with-zero  Initialize CRC with 0x000..000 (default is 0xFFF..FFF)
   -n --negate-final    Negate the final CRC result
   -t --self-test       Run integrated self-test and exit program

One output line is generated per input file:

<CRC64-Checksum>[SP]<File-Size>[SP]<File-Name>[LF]
