Zero Access to Your Email Content

Proton Mail's zero access architecture means your data is encrypted in a way that makes it inaccessible to us. Data is encrypted on the client side using an encryption key that Proton does not have access to, ensuring we cannot decrypt your messages.

Open-Source Cryptography

Proton Mail's open-source software has been rigorously vetted by security experts globally, ensuring the highest levels of protection. We utilize secure implementations of AES, RSA, and OpenPGP, with all cryptographic libraries being open source. This guarantees that the encryption algorithms used do not contain hidden back doors.
