					   uint32_t length,			 // The number of bytes in the 'big-number'; this will be 25 for a bitcoin address

					   char *output,			 // The address to store the output string.
					   uint32_t maxStrLen);		 // the maximum length of the output string

// Decode a previously encoded base58 string.  Returns the number of bytes in the decoded binary stream.  If there was an error decoded it
// then it returns a zero byte length.

					   bool outputIsBigEndian);		// Whether or not the output is considered big endian and therefore needs to be byte reverse; true for bitcoin addresses
