RSA算法是在1978年由Ron Rivest, AdiShamir 和Leonard Adleman提出的一种公钥加密算法。RSA能同时用于加密和数字签名的算法，也易于理解和操作。RSA是被广泛研究的公钥算法，从提出至今，经历了各种攻击的考验，逐渐为人们所接受，被普遍认为是目前最优秀的公钥方案之一。-RSA algorithm in 1978 by Ron Rivest, AdiShamir and Leonard Adleman proposed a public key encryption algorithm. RSA can be used for both encryption and digital signature algorithms, but also easy to understand and operate. RSA has been extensively studied is the public key algorithm, from the present, has undergone the test of various attacks, and gradually accepted, is generally considered the best public-key is currently one of the options.
