Ascii85 Encoding and Decoding

See more Encryption Examples

Demonstrates ascii85 encoding and decoding.

Note: Requires Chilkat v9.5.0.79 or greater.

Perl

use chilkat();

$success = 0;

# First demonstrate encoding strings to ascii85 and back.
$sb = chilkat::CkStringBuilder->new();

$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.");

$encodedAscii85 = $sb->getEncoded("ascii85","utf-8");
print $encodedAscii85 . "\r\n";

# 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");
print "Original:" . "\r\n";
print $sb->getAsString() . "\r\n";

# ---- Now encode binary data to ascii85 ----
$bd = chilkat::CkBinData->new();
$success = $bd->LoadFile("qa_data/jpg/starfish20.jpg");
$encodedAscii85 = $bd->getEncoded("ascii85");
print $encodedAscii85 . "\r\n";

# 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");
