During the script execution, util.base64Encoding is used for base64 encoding. 
base64Encoding(input: string | ArrayBuffer, encoding?: "std" | "rawstd" | "url" | "rawurl"): string

Background

The different base64 encoding methods are as follows:
StdEncoding is the standard Base64 encoding as defined in RFC 4648.
RawStdEncoding is the standard raw, unpadded base64 encoding as defined in Section 3.2 of RFC 4648; it is the same as StdEncoding but omits the padding characters.
URLEncoding is the alternate base64 encoding defined in RFC 4648, typically used for URLs and file names.
RawURLEncoding is the unpadded alternate base64 encoding defined in RFC 4648, typically used for URLs and file names; it is the same as URLEncoding but omits the padding characters.
