如何存储和比较使用非对称算法生成的加密字符串？ [英] How to store and compare encrypted string generated using asymmetric algorithm?

问题描述

我想将RSA算法生成的加密字符串存储在数据库中。据我所知，由于随机填充rsa将每次为相同的纯文本生成不同的加密字符串。有没有办法在c＃和sql中存储和比较这些值？



我尝试过：



我使用默认的rsacryptoserviceprovider类加密解密方法。

I would like to store encrypted string generated by RSA algorithm in database. As far as i know due to random padding rsa will generate different encrypted string every time for same plain text. Is there any way to store and compare these values in c# and sql?

What I have tried:

I am using default rsacryptoserviceprovider class encrypt decrypt methods.

推荐答案

解密它。除非你知道哪些位是随机填充，否则你无法比较它们 - 你不能比较它们！

Decrypt it. Unless you know which bits are the random padding, you can't compare them - and you don't!
