Detailed Description

Utilities for base64 and base64url encoding and decoding.

Member Function Documentation

Decode()

Result< std::string > iceberg::Base64::Decode ( std::string_view  encoded )

static

Base64 decode a string (standard alphabet: +/).

Handles optional padding ('=').

Parameters

encoded

The base64-encoded string.

Returns

Decoded string, or an error if the input contains invalid characters.

Encode()

std::string iceberg::Base64::Encode ( std::string_view  data )

static

Base64 encode a string (standard alphabet: +/).

The output is padded with '=' to a multiple of 4 characters.

Parameters

data	The string to encode.

Returns

The base64-encoded string.

UrlDecode()

Result< std::string > iceberg::Base64::UrlDecode ( std::string_view  encoded )

static

Base64url decode a string (URL-safe alphabet: -_).

Handles optional padding ('='). This variant uses '-' and '_' instead of '+' and '/' per RFC 4648 §5.

Parameters

encoded

The base64url-encoded string.

Returns

Decoded string, or an error if the input contains invalid characters.

UrlEncode()

std::string iceberg::Base64::UrlEncode ( std::string_view  data )

static

Base64url encode a string (URL-safe alphabet: -_).

This variant uses '-' and '_' instead of '+' and '/' per RFC 4648 §5 and emits no '=' padding, matching the encoding commonly used by JWTs.

Parameters

data	The string to encode.

Returns

The base64url-encoded string (without padding).
