RSA Real-World Use Cases & Key Sizes
Discover how RSA protects HTTPS, SSH, and code signing today.
Welcome
RSA protects communications worldwide. In this lesson we map RSA to real systems: HTTPS certificates, SSH authentication, code signing, and encrypted email.
RSA in TLS/HTTPS
TLS certificates contain the server's RSA or ECC public key. During the TLS handshake, the client uses this public key to verify the server's identity and establish a shared session key.
