GnuPG is used in this tip.
The private key will be imported in one GnuPG store and the public key in another store.
This will allow you to sign and verify the signature with isolated stores and thus be sure of the verification.

If you want to sign your_file
:
echo "your_password" | gpg --quiet --no-tty --batch --pinentry-mode loopback --passphrase-fd 0 \
--homedir /home/me/gpg_sign \
--armor --detach-sign your_file
A your_file.asc
will be created with the signature.
If you want to sign your_file
:
echo "your_password" | gpg --quiet --no-tty --batch --pinentry-mode loopback --passphrase-fd 0 \
--homedir /home/me/gpg_sign \
--armor --clear-sign your_file
A your_file.asc
will be created with the content of the file and the signature.
If you want to verify the signature of your_file
with your_file.asc
:
gpg --quiet --no-tty --batch --pinentry-mode loopback --passphrase-fd 0 \
--homedir /home/me/gpg_verify \
--verify your_file.asc your_file
If you want to verify the file and the signature of your_file.asc
:
gpg --quiet --no-tty --batch --pinentry-mode loopback --passphrase-fd 0 \
--homedir /home/me/gpg_verify \
--verify your_file.asc
