Any one of these three values can be used to identify the keypair for future use.

Enter a name, email address, and comment to associate with the key pair.

For example, 1y will set an expiration date of one year from the time of keypair creation.

Specify the duration the key should be valid in days, weeks, months, or years.

Select (1) RSA and RSA (default) for the type of key.

Several prompts will appear before the keypair is generated:

Create GPG Keysĭownload and install the most recent version of the GPG command line tools for Debian: sudo apt updateĬreate a new primary keypair: Advertisements gpg -full-generate-key This guide shows how to create your own keypair, distribute the public key to a receiver, and encrypt and decrypt a message on Debian 10 (Buster). This means anyone can send you a secure message if they have a copy of your public key. The recipient can then use their private key to decrypt the message. This asymmetric cryptographic system is ideal for secure communication, because all it requires is that the sender of the message have a copy of the receiver's public key before encrypting and sending the message. The public key can be shared with anyone, while the private key should be protected and secret to maintain the integrity of the system. Public-key cryptography uses a key-pair system where any single user has a private and public key pair. GPG uses a combination of symmetric-key cryptography and public-key cryptography.
