C# byte[][] SHA1

Question

I have this code in C# that uses IKVM to utilize Java's SHA1 encryption.

    public static string ComputeHash(params byte[][] bytes)
    {
        if (bytes == null) throw new ArgumentNullException("bytes");
        MessageDigest digest = MessageDigest.getInstance("SHA-1");
        foreach (var item in bytes)
        {
            if (item == null)
                if (bytes == null) throw new ArgumentNullException("bytes", "Inner array is null");
            digest.update(item);
        }
        string s = (new java.math.BigInteger(digest.digest())).toString(16);
        return s;
    }

Is there an alternative rather than using IKVM for this?

If I understand the question correctly, you could use the Sha1CryptoServiceProvider class in System.Security.Cryptography.

Here's the code example from that page:

byte[] data = new byte[DATA_SIZE];

byte[] result; 

SHA1 sha = new SHA1CryptoServiceProvider(); 
    // This is one implementation of the abstract class SHA1.

result = sha.ComputeHash(data);

I would not expect it to be too hard to change that example into one that takes jagged arrays.
