RSA Algorithm

Definition

The RSA algorithm is a public-key cryptographic system widely used for secure data transmission. This asymmetric encryption method relies on the mathematical difficulty of factoring large numbers into their prime factors, employing a pair of keys—a public key for encryption and a private key for decryption. RSA is fundamental for securing digital communications, authenticating digital signatures, and protecting sensitive information across networks. While not directly a blockchain consensus mechanism, its principles of public-key cryptography are foundational to securing cryptocurrency transactions and digital identities.
