// The ReEncode method converts a string from one encoding to another.
// Valid encodings are "url", "base64", "qp", "hex", "modbase64", "base64url", "base32", "base58",
// and any of the encodings listed here:  http://cknotes.com/chilkat-binary-encoding-list

// Convert from hex to base64
b64 := crypt.ReEncode(hex,'hex','base64');
Memo1.Lines.Add('base64: ' + b64);

// Convert from base64 to base32
b32 := crypt.ReEncode(b64,'base64','base32');
Memo1.Lines.Add('base32: ' + b32);

// Convert from base32 back to hex
hex := crypt.ReEncode(b32,'base32','hex');
Memo1.Lines.Add('hex: ' + hex);
