RSA公钥加密算法是1977年由Ron Rivest、Adi Shamirh和LenAdleman在（美国麻省理工学院）开发的。RSA取名来自开发他们三者的名字。RSA是目前最有影响力的公钥加密算法，它能够抵抗到目前为止已知的所有密码攻击，已被ISO推荐为公钥数据加密标准。RSA算法基于一个十分简单的数论事实：将两个大素数相乘十分容易，但那时想要对其乘积进行因式分解却极其困难，因此可以将乘积公开作为加密密钥。-The RSA public key encryption algorithm in 1977 by Ron Rivest, Adi Shamirh and LenAdleman (Massachusetts Institute of Technology) developed. RSA name from the development of their three names. RSA is the most influential public key encryption algorithm, it can resist all password attack known so far, has been recommended by the ISO Public Key Data Encryption Standard. The RSA algorithm is based on a very simple number theory fact: multiply two large prime numbers is very easy, but when you want to its product factorization is extremely difficult, so it can be the product of public as an encryption key.
