RapidCRC is an open source CRC/MD5/SHA hashing program. I've extended the current unicode support to allow writing of unicode .sfv/.md5/.sha1/.sha256/.sha512 files, which can be turned on/off through the settings page. Unicode sfv files are written as UTF-16LE with BOM or UTF-8 (with or without BOM), and RCRC now performs a codepage detection. I've also expanded the shell extension that was included in the sourcecode to enable all operations directly from the extension.

List of other new features:

multithreaded hash calculations with asynchronous I/O
ed2k hash calculation
SHA hash calculation
job queueing
popup menu to copy the calculated hashes to the clipboard

RapidCRC is released under the GPL - the sourcecode with my modifications can be found below. Be warned however that my documentation in the sourcecode is not as good as the original RapidCRC source.

Fixed a problem with configuring the shell extension menu
Added a win2k compatible portable download - this will probably not happen every release

v0.3.31

posted on 02/02/2020 - 20:45

Updated sha3 algorithms
Compiled with Visual Studio 2017. This removes win2k compatibility, but improves sha3 performance by 300%. If anyone is still using the win2k version let me know and I'll put up another build.

Update: there was a problem with the 32bit version, 0.3.31 should fix that.
