Specifying files
When referencing file names/paths that contain spaces, you must surround them with "speech marks":
$ kryptor -e "GitHub Logo.png"
$ kryptor -e "C:\Users\samuel-lucas6\Downloads\GitHub Logo.png"
Files in the same directory as the kryptor executable can be specified using a file name:
$ kryptor -e file.txt
However, files that aren't in the same directory must be specified using a file path:
$ kryptor -e C:\Users\samuel-lucas6\Documents\file.txt
Multiple files and/or directories can be specified at once:
$ kryptor -e file1.txt file2.jpg file3.mp4 Photos Videos
Specifying your private key
You can perform encryption, decryption, and signing with your default private key as follows:
$ kryptor -e file.txt
$ kryptor -d file.txt.bin
$ kryptor -s file.txt
This is the recommended approach, but it means your private keys must be kept in the default folder, which varies depending on your operating system:
Windows: %USERPROFILE%/.kryptor
Linux: /home/.kryptor
macOS: /Users/USERNAME/.kryptor
To specify a private key for -r|--recover, -m|--modify, or a private key not stored in the default folder, you must use the -x|--private option followed by :[file] like so:
$ kryptor -r -x:"C:\Users\samuel-lucas6\Documents\encryption.private"
