Quote:The secure email service, ProtonMail, now supports elliptic curve cryptography for enhanced security and speed, the team behind the product has announced. The company has been working for several months to implement support for new cryptographic methods which provide a faster experience with equal or greater security.
 
The firm has taken the decision include elliptic curve cryptography (ECC) alongside RSA encryption. It said ECC will become the default for all new addresses on ProtonMail but gives existing users the ability to upgrade their RSA addresses right now. In order to upgrade follow these instructions carefully:

1. Head to your ProtonMail inbox on desktop.
   
2. Go to SETTINGS.
   
3. Head to the Keys menu.
   
4. Press ADD NEW KEY, select the address you want to upgrade from the dropdown and press NEXT.
   
5. Select State-of-the-art and then GENERATE KEYS.
   
6. Under ADD NEW KEY you should see your email address, press the expand arrow.
   
7. On the ECC row, press the arrow next to EXPORT in the ACTIONS column and select MAKE PRIMARY. That’s it, do NOT delete the RSA key as it’s needed for reading old emails.
