I found an example of encrypting a string with SHA512.
public static string HashedString(string text)
{
SHA512Managed sha512 = new SHA512Managed();
byte[] hash = sha512.ComputeHash(Encoding.UTF8.GetBytes(text));
StringBuilder result = new StringBuilder();
foreach (byte b in hash)
result.Append(b);
return result.ToString();
}
But when I print on the screen the return of this method I realize that the result is in binary and I want it in hex.
That?
public static string HashedString(string text) {
var sha512 = new SHA512Managed();
byte[] hash = sha512.ComputeHash(Encoding.UTF8.GetBytes(text));
var result = new StringBuilder();
foreach (byte b in hash) result.Append($"{b:x2}");
return result.ToString();
}
See running on .NET Fiddle . And no Coding Ground . Also I put it in GitHub for future reference .
You need to say that you want it in hex if that's what you want. See What does the "$" symbol mean before a string? .
Where is
StringBuilder result = new StringBuilder();
foreach (byte b in hash)
result.Append(b);
return result.ToString();
replace with
return BitConverter.ToString(hash).Replace("-", "");
That way, you will not have n + 1 strings in the heap, but only 2.
