An easy to use public key encryption program for your YubiKey.
Supported YubiKey algorithms:
For encryption with slot 9d:
RSA: 2048, 3072, 4096 bits
For signing with slot 9c:
ECC: P-256, P-384, Ed25519
Simply use Yubico Authenticator to create your signing and
encryption certificate and export your encryption certificate,
to give it to your friends. You don't have to export your signing
certificate, because it is not needed for signature verification.
If you use Linux (Debian/Ubuntu) you may have to do the following
in order that yubicrypt works.
Install PC/SC daemon and tools
sudo apt update
sudo apt install pcscd pcsc-tools
Start the PC/SC daemon
sudo systemctl start pcscd
Enable it to start automatically on boot
sudo systemctl enable pcscd
Check the status to ensure it's running
sudo systemctl status pcscd
