hash_hmac method c#

[baileigh]

I'm trying to find analog a function. hash_hmac('sha512'.. for c#. Found the next code.

var rez= Hash("privet", GetBytes(12345));

c# Nzg3OGNmMmJhZGRiOTM4NTY1NTc4MjgwOGE3ZDNlNDFlMDBhNTBkMGY1NWFhMzJlM2RiNDkxZTUwMjQ5ODZkOTUwMWUyOWU0YzY1YTNlY2UwYzI0N2VmZGI5NmMxZjVlNGEwOTdhMGJlYmI2YzFlYTk1MmZjYjM5YWY0M2RlZTY=

And php $sign = hash_hmac('sha512', 'privet', '12345');

Where am I wrong, friends?

private string Hash(string message, byte[] secretKey)
{
    byte[] msgBytes = System.Text.Encoding.UTF8.GetBytes(message);
    byte[] hashBytes;
    using (HMACSHA512 hmac = new HMACSHA512(secretKey))
    {
        hashBytes = hmac.ComputeHash(msgBytes);
    }
    var sb = new StringBuilder();
    for (int i = 0; i < hashBytes.Length; i++)
        sb.Append(hashBytes[i].ToString("x2"));
    string hexString = sb.ToString();
    byte[] toEncodeAsBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(hexString);
    return System.Convert.ToBase64String(toEncodeAsBytes);
}
static byte[] GetBytes(string str)

{

byte[] bytes = new byte[str.Length * sizeof(char)];

System.Buffer.BlockCopy(str.ToCharArray(), 0, bytes, 0, bytes.Length);

return bytes;

}

Use the usual. Encoding.GetBytes To get a white key. And get the result. hexString I don't know how it is, don't encode his bikes again like base64. This is a working option that gives the same result you have in PHP:

private static string Hash(string message, string secretKey)
{
    var encoding = System.Text.Encoding.UTF8;
    byte[] msgBytes = encoding.GetBytes(message);
    var keyBytes = encoding.GetBytes(secretKey);
    using (HMACSHA512 hmac = new HMACSHA512(keyBytes))
    {
        byte[] hashBytes = hmac.ComputeHash(msgBytes);
    var sb = new StringBuilder();
    for (int i = 0; i < hashBytes.Length; i++)
        sb.Append(hashBytes[i].ToString("x2"));
    return sb.ToString();
}

}
static void Main(string[] args)

{

Console.WriteLine(Hash("privet", "12345"));

}
