【问题描述】:
我们使用 AAD B2C 和自定义策略已经有一段时间了,一切正常,但突然之间,我们开始在登录策略上遇到异常。更糟糕的是,有时它确实有效,但 5 次中有 4 次出现异常。
我们设法通过将策略链接到 Application Insights 来挖掘错误,这就是我们得到的结果:
"Kind": "FatalException",
"Content": {
"Time": "9:05 PM",
"Exception": {
"Kind": "Handled",
"HResult": "80131509",
"Message": "IDX10614: AsymmetricSecurityKey.GetSignatureFormater( 'http://www.w3.org/2001/04/xmldsig-more#rsa-sha256' ) threw an exception.\nKey: 'System.IdentityModel.Tokens.X509AsymmetricSecurityKey'\nSignatureAlgorithm: 'http://www.w3.org/2001/04/xmldsig-more#rsa-sha256', check to make sure the SignatureAlgorithm is supported.\nException:'System.Security.Cryptography.CryptographicException: Invalid provider type specified.\r\n\r\n at System.Security.Cryptography.Utils.CreateProvHandle(CspParameters parameters, Boolean randomKeyContainer)\r\n at System.Security.Cryptography.Utils.GetKeyPairHelper(CspAlgorithmType keyType, CspParameters parameters, Boolean randomKeyContainer, Int32 dwKeySize, SafeProvHandle& safeProvHandle, SafeKeyHandle& safeKeyHandle)\r\n at System.Security.Cryptography.RSACryptoServiceProvider.GetKeyPair()\r\n at System.Security.Cryptography.RSACryptoServiceProvider..ctor(Int32 dwKeySize, CspParameters parameters, Boolean useDefaultKeySize)\r\n at System.Security.Cryptography.X509Certificates.X509Certificate2.get_PrivateKey()\r\n at System.IdentityModel.Tokens.X509AsymmetricSecurityKey.get_PrivateKey()\r\n at System.IdentityModel.Tokens.X509AsymmetricSecurityKey.GetSignatureFormatter(String algorithm)\r\n at System.IdentityModel.Tokens.AsymmetricSignatureProvider..ctor(AsymmetricSecurityKey key, String algorithm, Boolean willCreateSignatures)'.\nIf you only need to verify signatures the parameter 'willBeUseForSigning' should be false if the private key is not be available.",
"Data": {},
"Exception": {
"Kind": "Handled",
"HResult": "80090014",
"Message": "Invalid provider type specified.\r\n",
"Data": {}
}
}
}
我不确定发生了什么变化,也不知道这件事发生得有多突然。我们是否使用隐身模式都没有关系。
此外,在 Microsoft 结束时没有报告中断。
任何线索将不胜感激!

不再是间歇性的,它一直在发生。
