how to implement SHA1 or MD5 in asp.net

Jaganathan Bantheswaran · Answer

Hi .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 { hashedValue .Append(hashData[i].ToString()); } hashedValue will have the MD5 hashed data.
