# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# Note: This example requires Chilkat v9.5.0.92 or greater.
# (In v9.5.0.92, the "itida" encoding was added to StringBuilder's Encode method.)

    exit;
}

# Convert the contents of sb to the ITIDA canonical form.
# Always pass utf-8 for the 2nd arg.
$sb->Encode("itida","utf-8");

# Get the lowercase hex encoded SHA256 hash of the canonicalized JSON
# (always use utf-8)
