Secure Mail Client: unified email operations inside CryptPeer

CryptPeer mail client centralizes email management in one application: multi-account setup, per-account PGP, PGP contacts, direct sending from the interface, sender-side outbox protection, and integrated translation.

A. Mail accounts

  • Add one or more mail accounts from a single interface.
  • Edit or remove accounts as your operational setup evolves.
  • Enable or disable accounts quickly without losing configuration.
  • Set up standard and advanced IMAP/SMTP parameters (servers, ports, security, authentication).
  • Run connection tests before production use.

B. Reading and organizing emails

  • Synchronize messages from all connected mail servers.
  • Navigate smoothly across core folders (inbox, sent, drafts, archives).
  • Read message content and metadata (sender, date, subject, attachments).

C. Composing and sending

  • Compose emails directly from the CryptPeer mail interface.
  • Reply, reply all, and forward from the same workspace.
  • Add attachments for day-to-day operational exchanges.
  • Send messages directly from the integrated webmail environment.

D. Additional tools

  • Translate email content with an option to display the original text.
  • Built-in guidance for application-password setup across providers.
  • Interface management options to adapt display and workflow to user context.

E. Security

  • SSL/TLS-secured IMAP/SMTP communication paths.
  • PGP integration based on each account's active configuration.
  • Major differentiator: CryptPeer automatically encrypts mail-client outboxes on the sender's terminal.
  • This upstream protection complements recipient-side protection and goes beyond most conventional mail clients.

F. Per-account PGP

  • Manage one PGP key pair per mail account.
  • Generate key pairs directly inside the application.
  • Protect private keys with a dedicated passphrase.
  • Import and export keys to fit your integration workflow.
  • Import recipients' public keys for encrypted delivery readiness.
  • asc format compatibility with many mail clients, including Thunderbird.

G. PGP contacts and encrypted sending

  • Maintain a trusted PGP contact list.
  • Import public keys to prepare secure exchanges.
  • Encrypt outbound emails to recipients whose public keys are registered.

H. Interoperability, advanced encryption and AI assistance (LLME)

Beyond per-account settings, the mail client fits into a PGP trust chain compatible with existing ecosystems while staying under local control.

  • Sender-side outbox protection: encryption of sensitive drafts and outbound material with AES-256 GCM on the terminal, complementing PGP message encryption where applicable.
  • PGP interoperability (ASC format): key exchange and messages with third-party clients (e.g. Thunderbird) when correspondents already rely on established tools.
  • External key handling: import and tracking of correspondents' public keys to streamline first secure exchanges.
  • Local AI assistance (LLME): help drafting or structuring messages with on-device processing — no content sent to external cloud AI. See the Local AI (LLME) sheet.

Differentiation block

Many email clients focus mainly on recipient-side encryption. CryptPeer also protects the sender-side outbox from the user's own terminal. This continuous protection model, from sender workstation to recipient, strengthens risk control for high-assurance organizations.
