# yubicrypt 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 ![yubicrypt](img/1.png) If you like yubicrypt, as much as I do, consider a small donation. ``` BTC: bc1qhgek8p5qcwz7r6502y8tvenkpsw9w5yafhatxk Nym: n1yql04xjhmlhfkjsk8x8g7fynm27xzvnk23wfys XMR: 45TJx8ZHngM4GuNfYxRw7R7vRyFgfMVp862JqycMrPmyfTfJAYcQGEzT27wL1z5RG1b5XfRPJk97KeZr1svK8qES2z1uZrS ``` Or, if you prefer, [buy me a coffee.](https://buymeacoffee.com/ch1ffr3punk) yubicrypt is dedicated to Alice and Bob.
