Can anyone help me how to run a gpg encryption command from a java program using Runtime.getRuntime().exec()?
sample command which I wanted to run shown below:
gpg -u 'receipient' -r KeyID --armor --output /home/myuser/tmp/check.pgp --sign --passphrase '&sw@217' --batch --encrypt /home/myuser/tmp/check.txt*
When I try to execute this from my Java program it gives error like "usage: gpg [options] [filename]"
Please help on resolving this error and run the above gpg command from a java program.
The following code should solve your problem if the gpg binary is correctly installed on your host.
Process p = new ProcessBuilder("gpg -u 'receipient' -r KeyID --armor --output /home/myuser/tmp/check.pgp --sign --passphrase '&sw@217' --batch --encrypt /home/myuser/tmp/check.txt*".split(" "))
.inheritIO()
.start();
p.waitFor();
I haven't the correct settings but this code runs as expected. You can try it here: https://tech.io/snippet/VzJtME0
