RSA is an asymmetric encryption algorithm based on the difficulty of factoring large prime numbers. Published in 1977, it remains widely used for key exchange, digital signatures, and encrypting small amounts of data. Common RSA key sizes are 2048 and 4096 bits, with 2048 as the current minimum recommendation.
RSA underpins most of today's PKI, TLS certificates, and code signing. Security engineers select RSA key sizes that balance performance with security margins. Penetration testers check for weak RSA keys in certificates. As quantum computing advances, RSA's long-term viability is a growing concern for security architects.
