|
|
======
|
|
|
|
Simple cross-platform command-line tool for computing **CRC-64** ([ECMA-182](https://www.ecma-international.org/wp-content/uploads/ECMA-182_1st_edition_december_1992.pdf)) checksums.
|
|
|
|
Generator polynomial: **`0x42F0E1EBA9EA3693`**
|
|
|
|
```
|
|
Synopsis:
|
|
crc64.exe [OPTIONS] [<file_1> [<file_2> ... <file_n>]]
|
|
|
|
Options:
|
|
--help --version Print help screen / show version information
|
|
--binary Output the digest in binary format (default is hex-format)
|
|
--decimal Output the digest in decimal string format
|
|
--upper-case Print hex-string as upper-case (default is lower-case)
|
|
--no-padding Print the digest *without* any leading zeros
|
|
--silent Suppress error messages
|
|
--ignore-errors Ignore I/O errors and proceeed with the next file
|
|
--no-flush Do *not* flush the standard output stream after each file
|
|
--init-with-zero Initialize CRC with zero (default is 0xFFF...FFF)
|
|
--negate-final Negate the final CRC result
|
|
```
|
|
|
|
One output line is generated per input file:
|
|
```
|
|
<CRC64-Checksum>[SP]<File-Size>[SP]<File-Name>[LF]
|
|
```
