copied!<p>I'm not sure what you mean when you say "only part of the string is being encrypted." Do you mean that you can still see some of the plaintext in <code>sTestToConvert</code> even after calling <code>Encrypt</code>?</p> <p>More likely, I expect you mean that when you call <code>Decrypt</code>, you only get part of the original string back.</p> <p>That's because <code>Encrypt</code> may store <em>any</em> byte value in the result, including non-printing characters, even <code>#0</code>, the null character. When you store such a string in a <code>TMemo</code> or <code>TEdit</code>, the underlying Windows control treats the <code>#0</code> character as the end of the string. It doesn't store the rest of the encrypted value. Thus, when you call <code>Decrypt</code> on what's stored in the edit control, you are only decrypting a portion of what you originally had.</p> <p>If you want to have a text version of the encrypted data, use the <code>Encode</code> and <code>Decode</code> functions; the <a href="http://help.madshi.net/madCryptUnit.htm" rel="noreferrer">documentation online</a> mentions this. Those use base-64 encoding.</p> <pre><code>procedure TForm1.Button1Click(Sender: TObject); var sTestToConvert: AnsiString; sPassword: AnsiString; begin sTestToConvert := Trim(Memo1.Text); sPassword := Trim(Edit1.Text); madCrypt.Encrypt(sTestToConvert, sPassword); Memo2.Text := madCryt.Encode(sTestToConvert); end; procedure TForm1.Button2Click(Sender: TObject); var sTextToConvert: AnsiString; sPassword: AnsiString; begin sPassword := Trim(Edit1.Text); sTextToConvert := madCrypt.Decode(Memo2.Text); madCrypt.Decrypt(sTextToConvert, sPassword); Memo1.Text := sTextToConvert; end; </code></pre>
