我正在尝试在我的coreclr项目中使用此class,但我似乎找不到SHA256Managed的正确包。我尝试过使用System.Security.Cryptography.Algorithms“:”4.0.0-beta-23409“但它不包含SHA2565Managed的实现。在coreclr中计算哈希值还有其他选择吗?
答案 0 :(得分:38)
您可以使用命名空间SHA256.Create()
System.Security.Cryptography
(大会:System.Security.Cryptography.Algorithms
)
using (var algorithm = SHA256.Create())
{
// Create the at_hash using the access token returned by CreateAccessTokenAsync.
var hash = algorithm.ComputeHash(Encoding.ASCII.GetBytes(response.AccessToken));
// Note: only the left-most half of the hash of the octets is used.
// See http://openid.net/specs/openid-connect-core-1_0.html#CodeIDToken
identity.AddClaim(JwtRegisteredClaimNames.AtHash, Base64UrlEncoder.Encode(hash, 0, hash.Length / 2));
}
