Age (Encryption)

Age is a public-key encryption system, similar in certain concepts to GnuPG (GPG)[1], but simpler because it isn't focused on building a web of trust.

Conveniently, Age can use not just its own keypairs, but also a person's SSH keypairs for encryption and decryption. This is nice because many systems already have authenticated SSH keypairs for each other.

• Easily Using SSH With FIDO2/U2F Hardware Security Keys[2]

A lot of new hardware security keys (Yubikey, Nitrokey, Titan, etc.) now support FIDO2 (aka U2F aka Webauthn aka Passkey; yes it's a mess).

• Signify[3]

Signify is a toool to create and verify signatures on files.

• Gnupg (GPG)[4]

GnuPG (also known by its command name, gpg) is a tool primarily for public key Encryption[5] and cryptographic authentication.

• Encrypting Filespooler Jobs With Age[6]

Like the process described in Encrypting Filespooler Jobs with GPG[7], Filespooler[8] can handle packets Encrypted[9] with Age (Encryption)[10]. Age may be easier than GnuPG in a number of cases, particularly because it can use a person's existing SSH keypairs for encryption.

• Encrypted[11]

Encryption is a way to encode data so that people that might intercept it can't decipher the original message (often called the "plaintext").
