gnupg - How do I import a private key into GPG so that it

A GPG key is actually a collection of keys. There is one primary key, which is typically used only for signing and certification. The suggested usage of GPG is to create a subkey for encryption. This subkey is a separate key that, for all intents and purposes, is signed by your primary key and transmitted at the same time To get around this issue, GPG relies on a security concept known as public key encryption. The idea is that you can split the encrypting and decrypting stages of the transmission into two separate pieces. That way, you can freely distribute the encrypting portion, as long as you secure the decrypting portion Recover RSA private key from public keys - rhme2 Key Server (crypto 200) - Duration: 12 In 3 Minutes - PGP/GPG Tutorial for Beginners - Duration: 3:04.
