Functions to encode/decode in Base64

Function Documentation

Base64Decode()

int Base64Decode	(	const char *	input,
		uint8_t *	outputbuf,
		const char *	pEndMarker = NULL )

#include <base64.h>

Decodes a null terminated Base64 string into bytes.

Notes:

• outputbuf should be at least the size of input divided by 4, rounded up
• Does not null terminate results

Parameters

input	Base64 string
outputbuf	Resulting decoded data
pEndMarker	Pointer to the end of the string (in the event it is not terminated by by either a null char or a base64 terminator)

Returns

Number of bytes returned in outputbuf

int Base64Encode	(	uint8_t *	input,
		int	inlen,
		char *	outputbuf )

#include <base64.h>

Encodes arbitrary binary bytes into Base64 string.

Notes: Does not null terminate results but terminates with an '='

Parameters

input	Data
inlen	Length of data
outputbuf	Resulting encoded data

Returns

Number of bytes returned in outputbuf

		uint8_t *	input,
		int	inlen,
		char *	outBuf,
		int	maxOutLen )

#include <base64.h>

Encodes arbitrary binary bytes into Base64 string and writes them to a file descriptor.

Notes: Does not null terminate results but terminates with an '='

Parameters

fd	Target File Descriptor
input	Data to be encoded
inlen	Length of data
outBuf	Temporary buffer to accumulate encoded data
maxOutLen	Maximum buffer space to accumulate data

Returns

Number of bytes returned in outputbuf

Base64UrlDecode()

int Base64UrlDecode	(	const char *	input,
		uint8_t *	outputbuf,
		const char *	pEndMarker = NULL )

#include <base64.h>

Decodes a null terminated Base64Url string into bytes.

Notes:

• outputbuf should be at least the size of input divided by 4, rounded up
• Does not null terminate results

Parameters

input	Base64Url string
outputbuf	Resulting decoded data
pEndMarker	Pointer to the end of the string (in the event it is not terminated by by either a null char or a base64 terminator)

Returns

Number of bytes returned in outputbuf
