Description: RSA is a cryptosystem for public-key encryption, and is widely used for securing sensitive data, particularly when being sent over an insecure network such as the Internet.A user of RSA creates and then publishes a public key based on the two large prime numbers, along with an auxiliary value. The prime numbers must be kept secret. Anyone can use the public key to encrypt a message, but with currently published methods, if the public key is large enough, only someone with knowledge of the prime numbers can feasibly decode the message Platform: |

Description: 椭圆曲线加密算法(ECC)是一种公钥算法，可以在不安全的信道上传递信息，而不需要事先约定密码。
RSA也是公钥算法，但是ECC比RSA有明显优势：在同等的安全程度下，所需要的密码长度最短。
但是缺点是算法本生很复杂，令人头大，我看了一堆书才写出了这个代码。
之前我发过一个256位的ECC源码，但是速度太慢了，这次这个是192位的，而且代码仔细优化过了，速度变快很多。(Elliptic curve cryptosystem (ECC) is a public key algorithm which can transmit information on unsafe channels without the need to pre contract passwords.
RSA is also a public key algorithm, but ECC has an obvious advantage over RSA: under the same security level, the required password length is the shortest.
But the drawback is that the algorithm is complex and big, and I read a bunch of books before I wrote the code.
I sent a 256 bit ECC source before, but it was too slow, this time it was 192 bits, and the code was carefully optimized, and the speed was faster.) Platform: |
