Careful Selection of the E‑Mail Mailbox Provider

You entrust everything to your e‑mail inbox: You receive new passwords and some business partners send you confidential documents unencrypted. In the associated address book you store contact data and other personal information. These must not get into the hands of strangers!

Secure Encryption for Dispatch and Storage

End-to-end encryption (E2EE) has not become widely accepted among the population. Most mails are therefore transported unencrypted if the sender and recipient use different mail service providers. Nevertheless, it is worth using a mailbox provider with this service, because at least then your e-mails are kept securely encrypted. Here I present a provider that relieves customers of the complicated encryption work. At first I listed two more mailbox providers, but because they use the now outdated PGP encryption standard and because this standard has several weaknesses, I would rather recommend a provider that does it better.

Introduction: Tutanota

Tutao GmbH was founded in November 2011 and has been on the market with its product Tutanota since March 2014. This mail provider is suitable for private and business use. Only provider of an end‑to‑end encrypted contact form for website operators!

Why no more Recommendation for Mailbox Providers with PGP?

Current encryption standards like PGP and S/MIME have weaknesses which Tutanota avoids.

These standards do not support Perfect Forward Secrecy (PFS) and are not resistant to quantum computers.

Furthermore, the subject of e‑mails should be encrypted. Therefore, the Tutanota team has developed a solution based on recognized algorithms (RSA and AES) that automatically encrypts subject, content and attachments.
In the future, it is planned to replace these algorithms with quantum-resistant algorithms.
