Specifying files
When referencing file names/paths that contain spaces, you must surround them with "speech marks":
1
$ kryptor -e "GitHub Logo.png"
2
$ kryptor -e "C:\Users\samuel-lucas6\Downloads\GitHub Logo.png"
Copied!
Files in the same directory as the kryptor executable can be specified using a file name:
1
$ kryptor -e file.txt
Copied!
However, files that are in a different directory to the kryptor executable (e.g. in your Documents folder) must be specified using a file path:
1
$ kryptor -e "C:\Users\samuel-lucas6\Documents\file.txt"
Copied!
Multiple files and/or directories can be specified at once:
1
$ kryptor -e file1.txt file2.jpg file3.mp4 Photos Videos
Copied!
Specifying your private key
You can use the -x|--private option without specifying a file path to use your default private key. However, in most cases, this option does not need to be specified. For example, you can perform encryption, decryption, and signing with your default private key as follows:
1
$ kryptor -e file.txt
2
$ kryptor -d file.txt.kryptor
3
$ kryptor -s file.txt
Copied!
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 or a private key not stored in the default folder, you must use the -x|--private option followed by :[file] like so:
1
$ kryptor -r -x:"C:\Users\samuel-lucas6\Documents\encryption.private"
Copied!
