We’re launching support for elliptic curve cryptography (ECC). Now your encrypted mailbox can benefit from faster and more advanced encryption. Learn the benefits of this new encryption method and how to upgrade your email addresses.

@protonmail if I mark my old keys as obsolete is it OK? I will still be able to view my old emails but not send new ones with those keys right? Ty

@tursiops @protonmail I already did that and it seems to be the case but I’d like to hear from someone at ProtonMail to be sure

@tursiops Hi! You’ll still be able to read your old emails as long as you don’t delete your old RSA keys.

@protonmail that's good to know. Then I've done everything right

I've made the switch to the new encryption. I'll be leaving the old key in place. Better safe than sorry.
