Detailed Description

Encodes and decodes byte streams using base64.

Member Function Documentation

decode() [1/2]

char * Base64::decode ( std::string_view src, char * dst )

static

Decodes a byte stream.

Parameters

src	The underlying string must be a multiple of 4 in length.
dst	Must be at least output_size<3, 4>(src.size()) in length.

Here is the caller graph for this function:

decode() [2/2]

static char * Base64::decode ( std::string_view src, char * dst )

static

Decodes a byte stream.

Parameters

src	The underlying string must be a multiple of 4 in length.
dst	Must be at least output_size<3, 4>(src.size()) in length.

encode() [1/2]

void Base64::encode ( std::string_view src, char * dst )

static

Encodes a byte stream.

Parameters

src	The underlying string must be a multiple of 3 in length, extra bytes beyond src.size() must be zero.
dst	Must be at least output_size<4, 3>(src.size()) in length.

Here is the caller graph for this function:

encode() [2/2]

static void Base64::encode ( std::string_view src, char * dst )

static

Encodes a byte stream.

Parameters

src	The underlying string must be a multiple of 3 in length, extra bytes beyond src.size() must be zero.
dst	Must be at least output_size<4, 3>(src.size()) in length.
