RSA Cryptography

Definition ∞ RSA Cryptography is a public-key cryptosystem widely used for secure data transmission. It relies on the computational difficulty of factoring large integers into their prime factors. RSA uses a pair of keys, a public key for encryption and a private key for decryption, allowing secure communication without prior sharing of a secret key. This algorithm is fundamental for digital signatures, secure communication, and identity verification across various digital platforms.
Context ∞ RSA Cryptography remains a standard for secure communication, though its vulnerability to quantum computing is a significant concern for long-term data security. Discussions focus on migrating to post-quantum cryptographic algorithms to preempt future threats. Future developments are concentrated on the research and standardization of quantum-resistant alternatives that can provide equivalent security guarantees.
