#### Base64 Encoding

Base64 is an encoding that allows a sequence of arbitrary bytes to be encoded as a sequence of printable ASCII characters. For the definition of Base64, see RFC 1421 or RFC 2045. Base64 is most commonly used as a MIME transfer encoding for email.

GLib supports incremental encoding using `g_base64_encode_step()` and `g_base64_encode_close()`. Incremental decoding can be done with `g_base64_decode_step()`. To encode or decode data in one go, use `g_base64_encode()` or `g_base64_decode()`. To avoid memory allocation when decoding, you can use `g_base64_decode_inplace()`.

Support for Base64 encoding was added in GLib 2.12.
