Base64Encode / Base64Decode

SyncJS provides two complementary functions for encoding and decoding data using standard Base64 (RFC 4648).

NOTE

These functions are available as of Syncplify Server! v7.1.1. If you are running an older version, upgrade to v7.1.1 or later to use them.

Base64Encode

function Base64Encode(text: string): string;

Encodes the string text using standard Base64 and returns the encoded result. The output uses the standard alphabet (A-Z, a-z, 0-9, +, /) with padding characters (=).

Parameter	Type	Requirement	Explanation
text	string	required	The string to encode

Return value	Explanation
string	The Base64-encoded form of the input

Example

var encoded = Base64Encode('Hello, World!');
// encoded === "SGVsbG8sIFdvcmxkIQ=="

Base64Decode

function Base64Decode(encoded: string): string;

Decodes a standard Base64-encoded string and returns the original text. Returns an empty string if the input is not valid Base64.

Parameter	Type	Requirement	Explanation
encoded	string	required	The Base64-encoded string to decode

Return value	Explanation
string	The decoded string, or "" if the input is invalid

Example

var decoded = Base64Decode('SGVsbG8sIFdvcmxkIQ==');
// decoded === "Hello, World!"

Practical use: Authorization header

var credentials = Base64Encode('alice:my-password');
var hc = new HttpCli();
var res = hc.Url('https://api.example.com/data')
             .Header('Authorization', 'Basic ' + credentials)
             .Get();
Log('Status: ' + res.StatusCode());
