       URL-safe Base64 Encoding & Decoding.

size_tjose_b64_dec(constjson_t*i,void*o,size_tol)
       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_tjose_b64_dec_buf(constvoid*i,size_til,void*o,size_tol)
       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(constjson_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(constvoid*i,size_til)
       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_tjose_b64_enc_buf(constvoid*i,size_til,void*o,size_tol)
       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(constjson_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.
