When it comes to secure web applications, we must keep sensitive data secure during the communication period. Sadly, while HTTPS encrypts data as it moves from point A to point B, the information is still exposed in a browser's network tab and can leak out this way. In this post, I will give you an example of implementing end-to-end encryption of API calls in your secure web app built with Angular.
Encryption Workflow
Weak protections have traditionally been obfuscation with Base64 encoding or custom schemes. Public key cryptography (PKC) is considered a modern solution to be more secure. It uses a key pair one public key for encryption, and the other private key for decryption. A public key is distributed and a private key is kept on the server.
