(Classic ASP) Hash the Contents of a String (SHA256 and other hash algorithms)Demonstrates how to hash the contents of a string using SHA256, SHA384, SHA512, MD2, MD5, HAVAL, RIPEMD, etc.

' See Unlock Chilkat Crypt for sample code. ' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Crypt2") set crypt = Server.CreateObject("Chilkat.Crypt2") ' Choose the hash algorithm.

' Let's examine the hash as a hex string. ' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.StringBuilder") set sb = Server.CreateObject("Chilkat.StringBuilder") success = sb.AppendEncoded(hashBytes,"hex") Response.Write "<pre>" & Server.HTMLEncode( "SHA256 hash = " & sb.GetAsString()) & "</pre>" %> </body> </html> |
