Name: base64Decode
Type: function
Syntax: the base64Decode of <encodedData>
Syntax: base64Decode(<encodedData>)
Summary:
<return|Returns> the original data from a base 64-<encode|encoded>
<string>.
Introduced: 1.0
OS: mac, windows, linux, ios, android
Platforms: desktop, server, mobile
Example:
put base64Decode(receivedData) into URL "file:download.mov"
Example:
base64Decode(base64Encode(myData))
Parameters:
encodedData (string):
A string of of any length. Valid base 64-encoded data can include
uppercase and lowercase letters, digits, +, /, and =. Other characters
are ignored.
Returns:
The <base64Decode> <function> <return|returns> the original <binary
file|binary data>.
Description:
Use the <base64Decode> <function> to take a base 64-<encode|encoded>
<string> and transform it back into the original <binary file|binary
data>.
The <base64Decode> <function> is the <inverse> of the <base64Encode>
<function>.
The decoded result is generally smaller than the encoded data.
Base 64-encoded data does not necessarily contain any = signs. If a run
of one or more = signs is present, it indicates the end of the data.
The base 64 encoding scheme is often used to encode binary data for MIME
mail and HTTP transfers.
For technical information about base 64 encoding, see [RFC 2045, section
6.8](https://tools.ietf.org/html/rfc2045#section-6.8).
