If a 3rd party, like an attacker, intercepts this email, they’ll also have the key.Īsymmetric encryption, on the other hand, uses two keys like we explained – private and public. The benefit of this method is that it is significantly faster, but also less safe since the same key has to be shared between the sender and the recipient in a safe way. In symmetric encryption, only one key is used to encrypt and decrypt. What is symmetric and asymmetric cryptography or encryption? This means that PGP uses both a public and private key and can take the efficiency from the symmetric system and the security of the asymmetric system. PGP is an encryption system developed in 1991 initially as freeware (until its purchase by Symantec in 2010 when it became a licensed software) that fuses two encryption standards: symmetric and asymmetric. On our blog, we already covered PGP encryption in detail, so we’ll give you a short version here. In this article, we’ll go over what PGP is and how it works and also show you how to set up PGP encryption on Linux step-by-step. ![]() ![]() If your email provider doesn’t protect you with PGP encryption, it’s not really secure.
