RSA stands for Rivest-Shamir-Adleman. RSA is an asymmetric encryption algorithm that uses a public key for encryption and a private key for decryption. It is widely used for digital signatures and key exchange.

How RSA Is Used in Cybersecurity

Cybersecurity teams rely on RSA for TLS certificate authentication and secure email signing. Security engineers generate RSA key pairs for SSH access and code signing. Penetration testers test for weak RSA key lengths and padding oracle vulnerabilities.
