MD5 hash with salt for keeping password in DB in C#

Question

Could you please advise me some easy algorithm for hashing user password by MD5, but with salt for increasing reliability.

Now I have this one:

Answer 1

You can use the HMACMD5 class:

var hmacMD5 = new HMACMD5(salt);
var saltedHash = hmacMD5.ComputeHash(password);

Works with SHA-1, SHA256, SHA384, SHA512 and RIPEMD160 as well:

var hmacSHA1 = new HMACSHA1(salt);
var saltedHash = hmacSHA1.ComputeHash(password);

Both salt and password are expected as byte arrays.

If you have strings you'll have to convert them to bytes first:

var salt = System.Text.Encoding.UTF8.GetBytes("my salt");
var password = System.Text.Encoding.UTF8.GetBytes("my password");
