By using open-source libraries, ProtonMail can guarantee that the encryption algorithms used do not have clandestinely built-in back doors. ProtonMail only uses secure implementations of AES, RSA, along with OpenPGP, while all of the cryptographic libraries used are open source.

ProtonMail's open-source software has been thoroughly vetted by security experts from around the world to ensure the highest levels of protection. This means we don't have the technical ability to decrypt your messages. Data is encrypted on the client side using an encryption key that Proton does not have access to. ProtonMail's zero access architecture means that your data is encrypted in a way that makes it inaccessible to us. This largely eliminates the risk of message interception. Messages are stored on ProtonMail servers using end-to-end encryption at all times and are transmitted in encrypted format between Proton servers and user devices.
