I have tried hashing a string in PHP using MD5 and the same in C#, but the results are different.. can someone explain me how to get this matched?
my C# code looks like
md5 = new MD5CryptoServiceProvider();
originalBytes = ASCIIEncoding.Default.GetBytes(AuthCode);
encodedBytes = md5.ComputeHash(originalBytes);
Guid r = new Guid(encodedBytes);
string hashString = r.ToString("N");
Thanks in advance
Edited: My string is 123 as a string
Outputs;
PHP: 202cb962ac59075b964b07152d234b70
C# : 62b92c2059ac5b07964b07152d234b70
Your problem is here:
Guid r = new Guid(encodedBytes);
string hashString = r.ToString("N");
I'm not sure why you're loading your encoded bytes into a Guid, but that is not the correct way to convert bytes back to a string. Use BitConverter
instead:
string testString = "123";
byte[] asciiBytes = ASCIIEncoding.ASCII.GetBytes(testString);
byte[] hashedBytes = MD5CryptoServiceProvider.Create().ComputeHash(asciiBytes);
string hashedString = BitConverter.ToString(hashedBytes).Replace("-", "").ToLower();
// hashString == 202cb962ac59075b964b07152d234b70
