This file was modified by jmarantz@google.com to:
|
||
|
|
- Add a static map and an initializer function
|
||
|
|
- add a web-safe variant that uses '-' and '_' in lieu of '+' and '/'
|
||
|
|
- change the 'decode' interface to return false if the input contains
|
||
|
|
characters not in the expected char-set.
|
||
|
|
- removed is_base64 helper function and instead rely on the char_maps.
|
||
|
|
- use a static constant for the padding character '='
