为什么我的 PHP SHA256 哈希不等同于 C# SHA256 托管哈希
为什么这些不一样?
断续器:
$hash = hash('sha256', $userData['salt'] . hash('sha256', $password) );
c#
public static string ComputeHash(string plainText, string salt)
{
// Convert plain text into a byte array.
byte[] plainTextBytes = Encoding.UTF8.GetBytes(plainText);
byte[] saltBytes = Encoding.UTF8.GetBytes(salt);
SHA256Managed hash = new SHA256Managed();
// Compute hash value of salt.
byte[] plainHash = hash.ComputeHash(plainTextBytes);
byte[] concat = new byte[plainHash.Length + saltBytes.Length];
System.Buffer.BlockCopy(saltBytes, 0, concat, 0, saltBytes.Length);
System.Buffer.BlockCopy(plainHash, 0, concat, saltBytes.Length, plainHash.Length);
byte[] tHashBytes = hash.ComputeHash(concat);
// Convert result into a base64-encoded string.
string hashValue = Convert.ToBase64String(tHashBytes);
// Return the result.
return hashValue;
}
