Privacy and decentralization is not only the basic principle of bitcoin and other cryptos but the WhatsApp you use also uses cryptography to keep your messages and calls private. WhatsApp uses end to end encryption for this.
WhatsApp uses SHA256 cryptography technology to keep messages and calls private
The messages, files, calls, and photos being sent from one person to another remain only between two people; no one else can see them “not even WhatsApp itself.”
WhatsApp is automatically activated as soon as someone installs WhatsApp; you do not need to start any settings for this.
When we install WhatsApp, we go through the public identity key and then the public sign key (digital signature), and then the WhatsApp server secures these keys on the server as your identity. I cannot use the WhatsApp key at any time.
Whenever we want to chat with someone on WhatsApp, we have to set up an encrypted session with that person, and once it is done, the information can be safe And transported to each other.
“AES256 of the message” is used to send the message, and HMAC -SHA256 coding is used for encryption.
Similarly, 32-byte SRTP is used to protect the call. The steps that have to be taken are shown below; –
WhatsApp has also introduced a payment transaction facility through WhatsApp in some countries where payments can be made from accounts to financial institutions.
This facility is again using this technology for security.
When you use your WhatsApp, you will know which technology you are using, and your messages and things are completely safe.
WhatsApp is a Facebook group project that works entirely on coding, and we can use these coding to keep information private and secure.
Cryptography and coding don’t just mean creating bitcoins and cryptos. Instead, if we use it properly, this technology can keep all kinds of confidential information secure.
