Try it yourself
An example you can run in a temporary verification environment.
printf '%s
' '--decrypt=decrypt ciphertext' '--output report.txt=write plaintext file'Expected result
--decrypt=decrypt ciphertext
--output report.txt=write plaintext fileKey points
- A private key is required
- Use --decrypt
- Protect the plaintext output
