[加密解密] RSA
编程实现RSA算法。包括：生成公钥(e, n)和私钥d，对明文m加密，对密文m解密。
注：实际应用中，512比特的n 已经不够安全，所以建议公司用1024比特的n，及其重要的场合用2048比特的 n。所以大家要选择大整数n。
Programming RSA algorithm. Include: Creation of a public key (e, n) and private key d, m the plaintext encryption, decryption of ciphertext m. Note: The actual application, the 512-bit n is not secure, it is recommended that companies with 1024-bit n, and the important occasion with a 2048-bit n. Therefore, we should choose a large integer n. (2011-03-23, Visual C++, 44KB, 下载158次)
