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 ...
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
RSA Decryption Similarly, for decryption, the process is the same. Here, you need to enter the RSA encrypted text and the result will be a plain-text. You have both the options to decrypt the encryption with either public or private keys. ...

RSA encryptionrelies on few basic assets and quite a bit of math. These elements are required: A public key (e) A private key (d) Two prime numbers (P and Q), multiplied (N) Security relies on the assumption that it's impossible to determine the value of d. The math that sits beh...
