如何使用RSA公钥和私钥对较大的字符串进行加密和解密 [英] How to encrypt and decrypt a larger string using RSA public and private key

问题描述

大家好，

实际上，我想加密一个更大的字符串并使用RSA公钥和私钥对其解密.但是实际上对于1024键大小发生了什么，我只能使用117个字节长的字符串.

Actually I want to encrypt a larger string and decrypt it using RSA public and private keys. But actually what is happening for a 1024 key size, I can only able to use 117 byte length string.

但是我想加密和解密一个更大的字符串.请有人给我一个想法或简单的解决方案来做到这一点.

But I want to encrypt and decrypt a larger string. Please someone give me an idea or simple solutions to do this.

此致

推荐答案

您能否提供到目前为止如何进行加密/解密的代码? 117byte的长度限制确实令人困惑，我想知道您做了什么.

can you give the code how you encrypt / decrypt so far? The 117byte length limit is really confusing and I am wondering what you did.

RsaCryproServiceProvide已经包含有关如何解密和加密的示例代码:
