What is the end to end ᴇɴɢʀyᴩᴛɪᴏɴ
End-to-end encryption (E2EE) is a method of securing communication where only the sender and the intended recipient(s) can read the messages being exchanged, making it virtually impossible for anyone else, including service providers and third parties, to access or intercept the content of the communication.
In end-to-end encryption, messages are encrypted by the sender's device or application before being sent, and can only be decrypted by the recipient's device or application. The encryption keys needed for decryption are only stored on the sender's and recipient's devices, and are not accessible by any other party, including the service provider or network operator.
This method of encryption provides a higher level of privacy and security, as the communication is protected from potential interception and surveillance by unauthorized parties. It is commonly used in messaging apps, email services, and other forms of digital communication.

End-to-end encryption (E2EE) works by encrypting the communication at the sender's end, and decrypting it at the recipient's end, with the encryption keys remaining secret and inaccessible to any other party. Here's a simplified explanation of how the process works:
Sender encrypts the message: When a user sends a message, it is encrypted on their device using a secret key. This secret key is unique to each conversation, and only the sender and the recipient(s) have access to it. The encrypted message is then sent over the internet to the recipient.
Message is transmitted: The encrypted message is transmitted over the internet from the sender's device to the recipient's device, passing through various servers and networks on the way.
Recipient decrypts the message: When the encrypted message arrives at the recipient's device, it is decrypted using the secret key that only the recipient has access to. The decrypted message can then be read by the recipient.
Encryption keys are kept secret: The encryption keys used to encrypt and decrypt the messages are kept secret and are not stored on any central server. This means that even if someone were to intercept the communication, they would not be able to read the content of the message without the secret key.

End-to-end encryption (E2EE) is a powerful security tool that can be used in various situations to protect sensitive information from interception and unauthorized access. Here are some common uses of E2EE:
Secure messaging: Messaging apps like WhatsApp, Signal, and Telegram use end-to-end encryption to protect the privacy and security of their users' conversations.
Email security: Encrypted email services like ProtonMail and Tutanota use end-to-end encryption to secure the content of emails from prying eyes.
Cloud storage: Cloud storage providers like Sync.com and SpiderOak use end-to-end encryption to secure user data stored on their servers.
File sharing: Services like Firefox Send and OnionShare use end-to-end encryption to securely share files over the internet.
Video conferencing: Platforms like Zoom and Microsoft Teams have added end-to-end encryption to their video conferencing features to provide an extra layer of security for sensitive meetings.
Financial transactions: End-to-end encryption is also used to secure online financial transactions, such as mobile banking and payment apps like Venmo and PayPal.

WhatsApp: A messaging app that uses end-to-end encryption by default to secure users' conversations and media shared within the app.
Signal: A messaging app that is widely regarded as one of the most secure messaging apps available. Signal uses end-to-end encryption for all communications, including messaging, voice calls, and video calls.
ProtonMail: An email service that uses end-to-end encryption to secure users' emails, contacts, and calendar data. ProtonMail also offers a VPN service that can be used to encrypt all internet traffic.
SpiderOak: A cloud storage provider that uses end-to-end encryption to secure user data stored on its servers. SpiderOak has a "zero-knowledge" policy, which means that the company cannot access users' data, even if it wanted to.
Zoom: A video conferencing platform that has added end-to-end encryption to its features to provide an extra layer of security for sensitive meetings.
LastPass: A password manager that uses end-to-end encryption to secure users' passwords and other sensitive data. LastPass is designed to be highly secure and is trusted by millions of users worldwide.
