不知是作者和我一样对于 C 语言并不“熟练”,还是倾向于使用 LUA,代码直接使用了2014年3月国外一位技术博客作者 Ravishanker Kusuma 的示例代码:RSA Encryption & Decryption Example with OpenSSL in C。 上面这段示例代码,或许也启发了前文中第一个库的方案,在 2014 年 123 月的时候,初代作者 doujiang24 的...

ThepublicKeyandprivateKeyvariables will be used for encryption and decryption respectively. Encryption We will use thepublicEncryptmethod for encrypting an arbitrary message. We must provide a few inputs to this method: The public key that we generated in the previous step ...
Here is an example of RSA encryption and decryption. The parameters used here are artificially small, but one can also use OpenSSL to generate and examine a real keypair. Choose two distinct prime numbers, such as and //233*9001 Compute n = pq giving //2097233 Compute the totient欧拉函数...

RSA encryption, type of public-key cryptography widely used for data encryption of e-mail and other digital transactions over the Internet. A user secretly chooses a pair of prime numbers p and q so large that factoring their product is well beyond proje
