URL-safe Base64 Encoding & Decoding.

Function Documentation

jose_b64_dec()

size_t jose_b64_dec	(	const json_t *	i,
		void *	o,
		size_t	ol
	)

Decodes a URL-safe Base64 JSON string to a buffer.

If o is NULL, the number of output bytes necessary is returned.

This function will never write more than ol bytes. If the output buffer is too small, an error will occur.

Parameters

i	The input URL-safe Base64 JSON string.
o	The output buffer (may be NULL).
ol	The size of the output buffer.

Returns

The number of bytes that were (or would be) written. If an error occurs, SIZE_MAX is returned.

jose_b64_dec_io()

jose_io_t* jose_b64_dec_io

(

jose_io_t *

next

)

Creates a new IO object which performs URL-safe Base64 decoding.

All data written to the returned IO object will be decoded before passing it on to the next IO object in the chain.

Parameters

next	The next IO object in the chain.

Returns

The new IO object or NULL on error.

jose_b64_dec_buf()

size_t jose_b64_dec_buf	(	const void *	i,
		size_t	il,
		void *	o,
		size_t	ol
	)

Decodes a URL-safe Base64 buffer to an output buffer.

If o is NULL, the number of output bytes necessary is returned.

This function will never write more than ol bytes. If the output buffer is too small, an error will occur.

Parameters

i	The input URL-safe Base64 buffer.
il	The size of the data in the input buffer.
o	The output buffer.
ol	The size of the output buffer.

Returns

The number of bytes that were (or would be) written. If an error occurs, SIZE_MAX is returned.

jose_b64_dec_load()

json_t* jose_b64_dec_load

(

const json_t *

i

)

Decodes a JSON string from a URL-safe Base64 JSON string.

Parameters

i	The input URL-safe Base64 JSON string containing JSON data.

Returns

The output JSON data.

jose_b64_enc()

json_t* jose_b64_enc	(	const void *	i,
		size_t	il
	)

Encodes data to a URL-safe Base64 JSON string.

Parameters

i	The input buffer.
il	The size of the data in the input buffer.

Returns

The decoded JSON data. If an error occurs, NULL is returned.

jose_b64_enc_io()

jose_io_t* jose_b64_enc_io

(

jose_io_t *

next

)

Creates a new IO object which performs URL-safe Base64 encoding.

All data written to the returned IO object will be encoded before passing it on to the next IO object in the chain.

Parameters

next	The next IO object in the chain.

Returns

The new IO object or NULL on error.

jose_b64_enc_buf()

size_t jose_b64_enc_buf	(	const void *	i,
		size_t	il,
		void *	o,
		size_t	ol
	)

Encodes data to a URL-safe Base64 buffer.

If o is NULL, the number of output bytes necessary is returned.

This function will never write more than ol bytes. If the output buffer is too small, an error will occur.

Parameters

i	The input buffer.
il	The size of the data in the input buffer.
o	The output URL-safe Base64 buffer.
ol	The size of the output buffer.

Returns

The number of bytes that were (or would be) written. If an error occurs, SIZE_MAX is returned.

jose_b64_enc_dump()

json_t* jose_b64_enc_dump

(

const json_t *

i

)

Encodes the input JSON as a URL-safe Base64 JSON string.

Parameters

i	The input JSON data.

Returns

The output URL-safe Base64 JSON string.
