RSA Meaning

RSA (Rivest-Shamir-Adleman) is one of the earliest and most widely used public-key cryptosystems for secure data transmission. It is based on the mathematical difficulty of factoring the product of two large prime numbers.

RSA allows users to encrypt data with a public key that can only be decrypted by a corresponding private key, forming the foundation for secure communications on the modern internet.The security of the algorithm is derived from the integer factorization problem. While it is computationally trivial for a computer to multiply two massive primes, it is nearly impossible for a classical computer to reverse the process and find the original factors.

However, because RSA requires very large key sizes (typically 2048 or 3072 bits) to remain secure against modern brute-force attacks, it is considered "heavy" compared to newer methods.In the blockchain world, RSA is generally not used for wallet addresses or transaction signatures. Instead, most chains use Elliptic Curve Cryptography (ECC) because it provides the same level of security with much smaller keys.

For example, a 256-bit ECC key is as secure as a 3072-bit RSA key, meaning less data needs to be stored on the ledger and transactions can be verified much faster by network nodes.
