Demonstrates how to RIPEMD hash a string using RIPEMD-128, RIPEMD-160, RIPEMD-256, and RIPEMD-320. Delphi ActiveX

procedure TForm1.Button1Click(Sender: TObject);

begin
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

crypt := TChilkatCrypt2.Create(Self);

content := 'abcdefghijklmnopqrstuvwxyz';

// The desired output is a hexidecimal string:
crypt.EncodingMode := 'hex';

// Set the hash algorithm:
crypt.HashAlgorithm := 'ripemd128';

hashStr := crypt.HashStringENC(content);
