base64_decode()

bool base64_decode	(	const std::string &	base64,
		std::string *	data
	)

Performs decoding of data from base64 format to binary.

Parameters

base64	base64 encoded data
data	decoded data will be written here.

Returns

true if decoding was successful. false if the encoding was erroneous, in which case the content of data is undefined.

Definition at line 113 of file Base64.cxx.

base64_encode()

std::string base64_encode

(

const std::string &

binary

)

Performs encoding of data in base64 format.

Parameters

binary

data to encode

Returns

base64 representation. The size will be (binary.size() + 2) / 3 * 4.

Definition at line 43 of file Base64.cxx.

nib64_to_byte()

unsigned nib64_to_byte

(

char

c

)

Decode a single base64 nibble.

Parameters

c	is the base64 nibble.

Returns

64 if this is the padding nibble; 65 if it's an invalid nibble, or 0..63 if it's a valid nibble.
