Posteo Encryption and Repository Planning
How Posteo Encryption Works
Posteo’s encryption is based on the OpenPGP standard, which ensures that emails are encrypted on the user’s device before they are transmitted to Posteo’s servers. This means that even Posteo’s administrators cannot access the content of users’ emails.
Key Components of Posteo Encryption
The encryption process involves the following components:
- Public and private key pairs: Each user has a unique pair of public and private keys, which are used to encrypt and decrypt emails.
- Key exchange: When a user sends an email to another Posteo user, their public keys are exchanged to establish a secure connection.
- Email encryption: The email is encrypted using the recipient’s public key and can only be decrypted with their private key.
