This separation is a great thing because symmetric algorithms like AES rely on a single private key, making them harder to secure since you need to share the secret key to allow someone else to send you an encrypted message. The TLS protocol used to enable HTTPS websites makes use of similar asymmetric encryption methods, for example. RSA is an asymmetric encryption method, meaning it uses a public key for encryption and a private key for decryption: anyone can send encrypted messages but only the receiver will be able to decrypt them. RSA is key to guaranteeing the security of your users, and understanding basic algorithms like RSA encryption helps prevent data breaches: 47% of data breaches are caused by negligence, and 37% of engineers have experienced a breach in their career! RSA presents several benefits as an encryption method.įirst, you cannot build reliable software solutions without proper data encryption. RSA will allow the receiver and the sender to communicate without having to fear leaking secrets, no matter the channel being used―be it a public Wi-fi network or your friend’s 3G hotspot. Privacy is a key requirement―you don’t want anybody to be able to monitor HTTP requests and find out what’s being said. Say you want to create an instant messaging app for example. RSA (Rivest–Shamir–Adleman) is an encryption algorithm used to securely transmit data over a communication channel. In this article, you’ll find a practical guide on RSA encryption you can use in your project using Python―purposes, libraries, best practices, and pitfalls to watch out for. But what if you need to send information over a non-secure network? How do you prevent network administrators or hackers from reading your HTTP or email traffic and retrieving sensitive data? RSA encryption & decryption is one way to go about it. 80% of websites use HTTPS, according to W3Tech.

At Onboardbase, we combine TLS (HTTPS) with RSA as an extra layer of security to prevent person-in–the-middle attacks.
