What encryption does OpenPGP use?
For this, PGP uses a hybrid cryptosystem by combining symmetric-key encryption and public-key encryption. The message is encrypted using symmetric encryption algorithm, which requires a symmetric key generated by the sender. The symmetric key is used only once and is also called a session key.
What is an OpenPGP public key?
PGP stands for Pretty Good Privacy and is used to encrypt email communications. It requires two keys — one public, the other private — to protect email from prying eyes. The sender needs to know the recipient’s public key to encrypt the message, and then the recipient uses his or her private key to decrypt it.

Which is the best encryption mode for OpenPGP?
OpenPGP supports two encryption modes. The most famous, and useful, is public key crypto where each user has his or her own private key that is kept confidential and the public key that is shared with anyone who needs to send encrypted messages. The Wikipedia article on public-key cryptography is a good place to start to read up on the foundation.
Where is the public key for OpenPGP stored?
My OpenPGP public key since 2003 is 0x1F9016AF. The normal mechanism for storing your private key is in a file on your computer that is protected by a passphrase, so it takes something you have (the key file) and something you know (the password) to decrypt messages or data that is encrypted to your associated public key.
What do you need to know about PGP encryption?
In addition to encryption, PGP can also create digital signatures. Signatures, created with your private key, are proof that you have written the message you have signed. Using your public keys, other users can verify these signatures.
What are the advantages of using subkeys in OpenPGP?
Another advantage to the use of the subkeys is that in the event of loss or theft of the secret keys of the subkeys, you only need to revoke the subkey without having to revoke the master key (the one that allows to certify other keys). Let’s start by creating the master key, the one that will hold our identity.
