如何创建AsymmetricSecurityKey？
提问于 2018-02-19 14:34:20
如何在c#中创建AsymmetricSecurityKey。实际上，我们正在使用AsymetricSecurityKey创建签名凭据，下面是我们的代码：
// Define const Key this should be private secret key stored in some safe place
string key = "401b09eab3c013d4ca54922bb802bec8fd5318192b0a75f201d8b3727429090fb337591abd3e44453b954555b7a0812e1081c39b740293f765eae731f5a65ed1";
// Create Security key using private key above:
// not that latest version of JWT using Microsoft namespace instead of System
var securityKey = new AsymmetricSecurityKey(Encoding.UTF8.GetBytes(key));
// Also note that securityKey length should be >256b
// so you have to make sure that your private key has a proper length
//
var credentials = new Microsoft.IdentityModel.Tokens.SigningCredentials

您可以使用以下命令生成公钥/私钥：
public void GenerateRsaCryptoServiceProviderKey()
{
var rsaProvider = new RSACryptoServiceProvider(512);
SecurityKey key = new RsaSecurityKey(rsaProvider);
}您应该使用下面的RsaSha256：
var credentials = new Microsoft.IdentityModel.Tokens.SigningCredentials
(key, SecurityAlgorithms.RsaSha256);Stack Overflow用户

您是否专门在寻找AsymmetricSecurityKey
我注意到您引用的是HM256算法。这让我相信你在找一个SymmetricSecurityKey。此外，您的方法似乎非常特定于使用HMAC alg。
要生成SymmetricSecurityKey，可以尝试执行类似以下代码的操作：
// Define const Key this should be private secret key stored in some safe place
string key = "401b09eab3c013d4ca54922bb802bec8fd5318192b0a75f201d8b3727429090fb337591abd3e44453b954555b7a0812e1081c39b740293f765eae731f5a65ed1";
// Create Security key using private key above:
// not that latest version of JWT using Microsoft namespace instead of System
var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(key));
// Also note that securityKey length should be >256b
// so you have to make sure that your private key has a proper length
//
var credentials = new Microsoft.IdentityModel.Tokens.SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256Signature);如果你想要一个使用RS256 alg的解决方案(它将使用pfx格式的证书)，你可以发表评论，我会尽我最大的努力给你一个例子。

这将从F#中的RSA公钥创建安全密钥。
