Understanding Email Encryption

PDG Mail uses multiple layers of encryption to protect your communications. This guide explains the different types of encryption and how they work together to keep your emails secure.

Types of Encryption

Transport Layer Security (TLS)

• Encrypts data in transit between servers
• Prevents man-in-the-middle attacks
• Automatically enabled for all connections

End-to-End Encryption (E2EE)

• Encrypts messages from sender to recipient
• Only the intended recipient can decrypt
• Uses PGP (Pretty Good Privacy) technology

Zero-Knowledge Architecture

• We cannot access your encrypted data
• You control your encryption keys
• No backdoors or master keys

How PGP Works

PGP encryption uses a combination of:

1. Public Key: Used to encrypt messages
2. Private Key: Used to decrypt messages
3. Digital Signatures: Verify message authenticity

Key Management

• Generate your key pair during account setup
• Store private key securely
• Share public key with contacts
• Regular key rotation recommended
