RSA - public-key cryptography

RSA is named by its inventors (Ron Rivest, Adi Shamir, and Leonard Adleman) (published in 1977), patented expired in 21 September 2000.

Speed for RSA in seconds no key blinding 1000 iteration, same rsa keys (1024 and 2048) operation performed each eteration sign, verify, encrypt, decrypt on a random bit pattern
