Add Base64-Encoded Data to a ZIP Using AddEncoded

See more Zip Examples

This example demonstrates how to use the AddEncoded method to add encoded binary data as a file entry within a ZIP archive.

The example adds Base64-encoded data as a file named hello.txt within the ZIP archive. The Base64 text is automatically decoded to its original binary bytes before being stored in the ZIP.

This method is useful when binary data already exists in encoded textual form, such as Base64 or hex.

Lua

local chilkat = require("chilkat")

local zip = chilkat.Zip.new()

local success = zip:new_zip("encodedData.zip")
if not success then
    print(zip.last_error_text)
    return
end

-- Base64 for the text: "Hello World!"
local base64Data = "SGVsbG8gV29ybGQh"

-- Add the decoded bytes as "hello.txt" within the ZIP archive.
success = zip:add_encoded("hello.txt", "base64", base64Data)
if not success then
    print(zip.last_error_text)
    return
end

-- Write the ZIP archive to disk and close it.
success = zip:write_zip_and_close()
if not success then
    print(zip.last_error_text)
    return
end

print("ZIP archive created successfully.")
