The term "end-to-end encryption" originally only meant that the communication is never decrypted during its transport from the sender to the receiver. [9] For example, around 2003, E2EE has been proposed as an additional layer of encryption for GSM [10] or TETRA, [11] in addition to the existing radio encryption protecting the communication between the mobile device and the network infrastructure.
Proton Mail uses a combination of public-key cryptography and symmetric encryption protocols to offer end-to-end encryption. When a user creates a Proton Mail account, their browser generates a pair of public and private RSA keys: The public key is used to encrypt the user's emails and other user data.
Proton Mail was released as a public beta on 16 May 2014 [6] as an end-to-end encrypted email service after a year of crowdfunding, by a group of scientists who met at CERN. [7] [8] Proton Mail 2.0 was released 14 August 2015, with open source front-end clients and a rewritten codebase.
Most email software and applications have an account settings menu where you'll need to update the IMAP or POP3 settings. When entering your account info, make sure you use your full email address, including @aol.com, and that the SSL encryption is enabled for incoming and outgoing mail.
Encryption scrambles and unscrambles your data to keep it protected. • A public key scrambles the data. • A private key unscrambles the data. Credit card security. When you make a purchase on AOL, we'll only finish the transaction if your browser supports SSL.

A general downside of end to end encryption schemes—where the server does not have decryption keys—is that it makes server side search almost impossible, thus impacting usability. The content of an email can also be end-to-end encrypted by putting it in an encrypted file (using any kind of file encryption tool [ 9 ] ) and sending that ...
Examples of end-to-end encryption include PGP, and ProtonMail, and S/MIME for email; OTR, iMessage, Signal, or Telegram and more recently WhatsApp for instant messaging; SpiderOak for backup and its Collaboration_tool Semaphor; ZRTP or FaceTime for telephony; and TETRA for radio. → Protonmail is a webmail and performs key-management on server ...
