问题 I am getting the following error message when I convert from .net 4.5 to .net core 2. The code is exactly the same. I have seen a few posts but none have solve this error. I am using RijndaelManaged encryption.

unity3d 使用IL2Cpp导出android工程报以下错误解决方法 重点是这块 “ ”System.Reflection.TargetInvocationException: ���õ�Ŀ�귢�����쳣�� ---> System.InvalidOperationException: ��ʵ�ֲ��� Windows ƽ̨ FIPS ��֤�ļ����㷨��һ���֡� �� System.Security.Cryptography.MD5CryptoServiceProvider..ctor()“” 参考C#报这种错误的解决办法 C#程序执行到运用到哈希算法或MD5算法 ,报错提示: System.InvalidOperationException: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms. at System.Security.Cryptography.MD5CryptoServiceProvider..ctor() 此实现不是 Windows 平台 FIPS 验证的加密算法的一部分。 解决方法如下: 在window中打开功能里输入regedit,回车打开注册器。然后进入如下路径中 重点是这句 HKEY_LOCAL

Python实现RSA无填充加密,兼容BouncyCastle

老子叫甜甜 提交于 2020-05-01 03:56:18
场景 某系统登录时密码经过前台rsa加密传给后端,为实现模拟登录需要原样生成加密串。 分析 前台通过RSA.js、BigInt.js、Barrett.js三个js文件实现加密,公钥通过ajax请求获得empoent、module。 rsa算法其实就是通过这两个参数计算实现公钥加密,所以正常情况下使用常规加密库即可达到目的。 但实际测试发现使用cryptography、pycryptodem等库加密结果与js输出不一致且每次都不同。其实常规库会按一定规则对原文随机填充后再加密,这样可保证相当的安全性。 于是考虑如何用python实现无填充的加密。 代码 经过搜索发现了相当简单(不安全)的实现方式,代码如下: if __name__ == ' __main__ ' : # 实为16进制串,前补0 e = ' 010001 ' # m也需要补00 m = '

NodeJS: bcrypt vs native crypto

柔情痞子 提交于 2020-04-29 04:29:08
问题 Can someone point out the differences between the two and example situations where use each? bcrypt looks great. 回答1: Use bcrypt where you want to do slow and computationally expensive hashing -- this will generally be for hashes where you really don't want an attacker to be able to reverse the hash, e.g. user passwords. Use native crypto for everything else. 回答2: In companion with the @mike-scott's answer, you should prefer bcrypt for password related stuff but still you can use crypto for a

SHA256withRSA what does it do and in what order?

萝らか妹 提交于 2020-04-28 04:14:39
问题 I'm a total newbie when it comes to cryptography and such things. I don't (and dont want to) know the details of the SHA256 and RSA. I "know" what they do, not how they do it, and for now that's enough. I'm wondering what the "SHA256withRSA"-algorithm (if you can call it that) actually do and in what order. For example, does it hash the data with SHA256 and then encrypts it using RSA or is it vice-versa, or something else? The reason I'm asking is because I wanna do the java equivalent of:
