This is a small implementation of base64 encode and decode functions designed for embedded systems. No dynamic memory is needed. However, a fair amount of static memory is needed for the lookup tables.

Storage of the lookup tables can be adapted using the BASE64_LOOKUP_TABLE_SECTION define. If it is set, the lookup table will be moved to the section specified by the define. Example:

#define BASE64_LOOKUP_TABLE_SECTION ".bss"
