jose_b64 - URL-safe Base64 Encoding & Decoding.


size_t jose_b64_dec (const json_t *i, void *o, size_t ol)
Decodes a URL-safe Base64 JSON string to a buffer. jose_io_t * jose_b64_dec_io (jose_io_t *next)
Creates a new IO object which performs URL-safe Base64 decoding. 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. json_t * jose_b64_dec_load (const json_t *i)
Decodes a JSON string from a URL-safe Base64 JSON string. json_t * jose_b64_enc (const void *i, size_t il)
Encodes data to a URL-safe Base64 JSON string. jose_io_t * jose_b64_enc_io (jose_io_t *next)
Creates a new IO object which performs URL-safe Base64 encoding. 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. json_t * jose_b64_enc_dump (const json_t *i)
Encodes the input JSON as a URL-safe Base64 JSON string.

URL-safe Base64 Encoding & Decoding.

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_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.

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.

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.

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_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.

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.

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.
