byte[] hashByte = Encoding.UTF8.GetBytes(tb_password.Text);
SHA512Managed sha512 = new SHA512Managed();
byte[] hash = sha512.ComputeHash(hashByte);

string saltwithhash = Convert.ToBase64String(hash);
Can I use this method to hash?

Does this regex allows email without @

How about storing hash + salt as a byte[] array. Can you compare both or must strip out the salt value first?

polkj 6-Jul-14 11:24am View

for instance when logging in i need to compare the hashes before logging in. So store as a string or byte[] array

polkj 6-Jul-14 10:42am View

So in the database is byte[] array not string?
