Seal - Encrypted Email Client

Seal, an end-to-end encryption email client makes it impossible for anyone to read your emails except the sender and recipient, like Outlook with encryption.

Emails are encypted on the client side using the encryption keys that email accounts providers have no access to. This means the email service providers do not have the ability to spy your messages.

Create your own key pairs containing private and public keys on your device. Share public keys with your contacts to encrypt emails, and use private keys to decrypt them.

Leveraging ECC public-key cryptography and AES from Apple's operating system, we guarantee encryption algorithms free from clandestine backdoors.

Support common email accounts with IMAP and SMTP, such as Gmail, iCloud etc.

-----------------------------------------------
With the Seal app, you can:
- Add your email accounts using app passwords provided by your email service providers, like setting in Outlook.
- Create your own key pairs, comprising public and private keys.
- Add your friends' contact.
- Send and receive encrypted emails and attachments via IMAP and SMTP.
- Encrypt message and files.

Embark on secure communication journeys like Alice and Bob with our email encryption app.
Alice and Bob each generate their own key pairs, comprising public and private keys. Alice's keys are denoted as (A, a), while Bob's are (B, b).
With their keys securely stored locally, Alice and Bob exchange public keys via email and save them for future communication.
Alice crafts her message, encrypting it with Bob's public key (B) to produce ciphertext. This encrypted message is then seamlessly sent to Bob.
Upon receipt, Bob employs his private key (b) to decrypt the ciphertext, revealing Alice's original message.

Experience the privacy and security by sealing your emails.

Privacy:
We will never collect and upload your encryption keys and data. All your data are encrypted and stored in your device and private iCloud.
