RSA
Noun | /ˌɑːr ɛs ˈeɪ/
A widely used public-key cryptosystem named after its creators (Rivest-Shamir-Adleman) that enables secure data transmission through asymmetric encryption. Uses mathematically linked public and private key pairs.
Key Characteristics:
- Based on factorization of large prime numbers
- Key sizes typically 2048-4096 bits
- Used for SSL/TLS, digital signatures, and secure communications
Example:
“Your web browser uses RSA encryption when establishing secure HTTPS connections.”
