Picocrypt 1.13 (Unstable, Known Bugs)
v1.13 is completely rewritten in Go instead of Python, and since I've also added many new features, there will (obviously) be a couple of bugs. Thus, don't use it for production. On Windows, Picocrypt can be detected as a virus. Please do your part and submit it as a false positive to your antivirus provider. Other than that, I hope you enjoy this release!
Edit: There is a known bug on Windows where when decrypting folders, you may end up with a file with no extension, or an invalid .zip file. Don't panic! If you don't have a .zip extension, add it. If Windows says the .zip is invalid, open it with 7-Zip and everything will work. This issue will be fixed in the next release. Also, keyfile support seems to be a little buggy.
Windows: Picocrypt.exe
macOS: Work in progress
