Detailed Description

Functions for encoding to and decoding from base64 and base64url.

NOTE: When successful, the output of each function MUST be released by calling free(), even if the output is of 0 length.

Function Documentation

cjose_base64_decode()

bool cjose_base64_decode	(	const char *	input,
		const size_t	inlen,
		uint8_t **	output,
		size_t *	outlen,
		cjose_err *	err )

Decodes the given string from Base64.

NOTE: output is NOT NULL-terminated.

Parameters

input	The text string to decode.
inlen	The length of input.
output	The decoded octet string.
outlen	The length of output.
err	[out] An optional error object which can be used to get additional information in the event of an error.

cjose_base64_encode()

bool cjose_base64_encode	(	const uint8_t *	input,
		const size_t	inlen,
		char **	output,
		size_t *	outlen,
		cjose_err *	err )

Encodes the given octet string to Base64.

Parameters

input	The octet string to encode.
inlen	The length of input.
output	The encoded text string.
outlen	The length of output (not including the terminating NULL).
err	[out] An optional error object which can be used to get additional information in the event of an error.

cjose_base64url_decode()

bool cjose_base64url_decode	(	const char *	input,
		const size_t	inlen,
		uint8_t **	output,
		size_t *	outlen,
		cjose_err *	err )

Decodes the given string from URL-Safe Base64.

NOTE: output is NOT NULL-terminated.

Parameters

input	The text string to decode.
inlen	The length of input.
output	The decoded octet string.
outlen	The length of output.
err	[out] An optional error object which can be used to get additional information in the event of an error.

cjose_base64url_encode()

bool cjose_base64url_encode	(	const uint8_t *	input,
		const size_t	inlen,
		char **	output,
		size_t *	outlen,
		cjose_err *	err )

Encodes the given octet string to URL-safe Base64.

Parameters

input	The octet string to encode.
inlen	The length of input.
output	The encoded output string.
outlen	The length of output (not including the terminating NULL).
err	[out] An optional error object which can be used to get additional information in the event of an error.
