.Net provide various namespaces to implement SHA1 and MD5 Hash Algorithms. System.Security.Cryptography.
MD5 md5 = MD5.Create(); // For SHA1 use, SHA1.Create();
byte[] hashData = md5.ComputeHash(Encoding.Default.GetBytes(data));
StringBuilder hashedValue = new StringBuilder();
for (int i = 0; i < hashData.Length; i++)
{
hashedValue .Append(hashData[i].ToString());
}
hashedValue will have the MD5 hashed data.
