PGP – Flexible and Decentralized Email Security

PGP (Pretty Good Privacy) is a powerful standard for email encryption and signature.

Functions of PGP

Similar to S/MIME, PGP enables secure communication through two essential functions:

1. Encryption:
   • Protects the content of your messages from unauthorized access, as they can only be decrypted by the intended recipient.
   • Perfect for confidential information, such as personal data or sensitive documents.
2. Signature:
   • Confirms the authenticity and integrity of your messages.
   • The recipient can ensure that the message actually comes from you and has not been altered.

Guide: Creation and Management of Key Pairs

PGP is based on the use of key pairs – a public key (for encryption) and a private key (for decryption). Here's how you can create and manage these in the vault:

1. Navigate to the Cryptography section:
   • In the dashboard, you'll find the menu item "Cryptography". Click on it and select the "PGP" tab.
2. Create new key pair:
   • Click on "Create key pair".
   • Enter a name for the key pair (e.g., "Marketing Team").
   • Choose the desired key length (recommended: 2048 or 4096 bits).
3. Export public key:
   • After the key pair has been created, you can export the public key and share it with your communication partners.
4. Securely store private key:
   • The private key is automatically stored in the vault and is only accessible to authorized users.
5. Import keys (optional):
   • If you already have an existing key pair, you can add it using the "Import key" function.
