jose_b64(3) Library Functions Manual jose_b64(3) NAME jose_b64 - URL-safe Base64 Encoding & Decoding. SYNOPSIS Functions 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. Detailed Description URL-safe Base64 Encoding & Decoding. Function Documentation 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_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. 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. 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. 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_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. 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. 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. Author Generated automatically by Doxygen for Jos from the source code. Jos Tue May 30 2017 jose_b64(3)
