Decimal Integer List Encoding

See more Encryption Examples

The "decList" encoding was added in Chilkat v9.5.0.66 to encode and decode binary bytes from comma-separated decimal integers. Delphi ActiveX

// Demonstrate encoding/decoding comma-separated decimal integrs to/from binary.
binData := TChilkatBinData.Create(Self);
binData.AppendEncoded(byteVals,'decList');

// Examine the data in hex
Memo1.Lines.Add('HEX: ' + binData.GetEncoded('hex'));

// Decode to a StringBuilder
sb := TChilkatStringBuilder.Create(Self);
sb.AppendBd(binData.ControlInterface,'us-ascii',0,0);

// The bytes were actually the us-ascii char values for the string
// "The true sign of intelligence is not knowledge but imagination."
Memo1.Lines.Add(sb.GetAsString());

// Now get the bytes in decimal list format again:
Memo1.Lines.Add(binData.GetEncoded('decList'));

// The output of this example is:
// HEX: 5468652074727565207369676E206F6620696E74656C6C6967656E6365206973206E6F74206B6E6F776C656467652062757420696D6167696E6174696F6E2E
