Ascii85 Encoding and Decoding

See more Encryption Examples

Demonstrates ascii85 encoding and decoding.

Note: Requires Chilkat v9.5.0.79 or greater.

C#

bool success = false;

// First demonstrate encoding strings to ascii85 and back.
Chilkat.StringBuilder sb = new Chilkat.StringBuilder();

success = sb.Append("Man is distinguished, not only by his reason, but by this singular passion from other animals, which is a lust of the mind, that by a perseverance of delight in the continued and indefatigable generation of knowledge, exceeds the short vehemence of any carnal pleasure.");

string encodedAscii85 = sb.GetEncoded("ascii85","utf-8");
Debug.WriteLine(encodedAscii85);

// Result is: 9jqo^BlbD-BleB1DJ+*+F(f,q/0JhKF<GL>Cj@.4 ... DII?(E,9)oF*2M7/c

// Decode back to the original:
sb.Clear();
sb.Append(encodedAscii85);
success = sb.Decode("ascii85","utf-8");
Debug.WriteLine("Original:");
Debug.WriteLine(sb.GetAsString());

// ---- Now encode binary data to ascii85 ----
Chilkat.BinData bd = new Chilkat.BinData();
success = bd.LoadFile("qa_data/jpg/starfish20.jpg");
encodedAscii85 = bd.GetEncoded("ascii85");
Debug.WriteLine(encodedAscii85);

// Result is:  s4IA0!"_al8O`[\!<E0k!([(is8E!F7VQ[M+Eqj?FED)3+C]U=6"Fn ...

// Decode...
bd.Clear();
bd.AppendEncoded(encodedAscii85,"ascii85");
success = bd.WriteFile("qa_output/starfish20.jpg");
