End-to-end encryption prevents data from being read or secretly modified, except by the true sender and intended recipients. Frequently, the messages are relayed from the sender to the recipients by a service provider. However, messages are encrypted by the sender and no third party, including the service provider, has the means to decrypt them ...
The end of the Cold War allowed ASEAN countries to exercise greater political independence in the region, and in the 1990s, ASEAN emerged as a leading voice on regional trade and security issues. [32] On 15 December 1995, the Southeast Asian Nuclear-Weapon-Free Zone Treaty was signed to turn Southeast Asia into a nuclear-weapon-free zone. The ...
In many end-to-end encryption services, to initiate communication a user will reach out to a central server and request the public keys of the user with which they wish to communicate. [2] If the central server is malicious or becomes compromised, a man-in-the-middle attack can be launched through the issuance of incorrect public keys.
Integrity protection mechanisms such as MACs and digital signatures must be applied to the ciphertext when it is first created, typically on the same device used to compose the message, to protect a message end-to-end along its full transmission path; otherwise, any node between the sender and the encryption agent could potentially tamper with it.
On April 5, 2016, WhatsApp and Open Whisper Systems announced that they had finished adding end-to-end encryption to "every form of communication" on WhatsApp, and that users could now verify each other's keys. [27] [28] In February 2017, WhatsApp announced a new feature, WhatsApp Status, which uses the Signal Protocol to secure its contents. [29]
SSL (Secure Sockets Layer) is an industry standard for encrypting private data sent over the Internet to help protect your account and information. Learn what SSL is and how we use it to protect your account.

First layer of the encryption: The ciphertext of the original readable message is hashed, and subsequently the symmetric keys are encrypted via the asymmetric key – e.g. deploying the algorithm RSA. In an intermediate step the ciphertext, and the hash digest of the ciphertext are combined into a capsule, and packed together.
