密码学原理【Crypto++ 实现】RSA加密

Requirements

请用 Crypto++实现一 个程序，具有加密和解密两种功能。在用加密功能时，读出一个名为“key.txt” 的文件中的 1024 位的密钥，一个名为“plain.txt”的文件中的一段不超过 1000 位的明文，用 RSA 加密后，密文写入一个叫做“encrypted.txt”的文件。在用解密功能时，读出一个名为“key.txt”的文件中的 1024 位的密钥，一个名为 “encrypted.txt”的文件中的密文，用 RSA 解密后，密文写入一个叫做 “decrypted.txt”的文件。所有文件格式均为纯文本，密钥、明文、密文均用 二进制书写，形如“00111010…”。请提交全部源代码。

RSA_Encryption Description

key: 1024 bits from “key.txt”
plaintext: less than 1000 bits from “plain.txt”
ciphertext: “encrypted.txt”
Encryption: RSA
Description: RSA
recovered: “descrypted.txt”

43 byte(s) Random String Generated Successfully in plain.txt
1024 bits saved in key.txt
1024 bits saved in d.txt
8 bits saved in e.txt
Plaintext is the following:
