// UU encode:
s2 := crypt.EncodeString(s1,'ansi','uu');

// Note: Call crypt.Encode instead of crypt.EncodeString
// to UU encode binary bytes (i.e. non-text binary data).

// UU decode:
crypt2 := TChilkatCrypt2.Create(Self);
s3 := crypt2.DecodeString(s2,'ansi','uu');

// Note: Likewise, call crypt.Decode to decode non-text binary data.

Memo1.Lines.Add(s3);

// Show the file permissions mode and filename found
// in the UU encoded data:
Memo1.Lines.Add('UuMode = ' + crypt2.UuMode);
Memo1.Lines.Add('UuFilename = ' + crypt2.UuFilename);
