Post-quantum cryptography is being developed, benchmarked, tested, discussed, and elaborated... Let me join in on that with a little practical software piece. falcon-cli is a CLI tool to sign and verify files with the post-quantum signature scheme FALCON, a round 3 finalist for digital signature algorithms in NIST's post-quantum cryptography standardization competition.
The tool supports keygen, file sign and verify ops, as such it is complete and ready for common file signature use cases. Imagine - now you can sign your Github Releases with (probably) post-quantum safe signatures and chill (4ever)...
Usage should be straightforward when glimpsin' over the README. The default key location shouldn't be surprisin' as well: ~/.falcon-cli/(public|secret).key. Also, if explicit input or output files are omitted, the tool falls back to stdin and stdout for IO.
In case of any issues get at me on GitHub.
