ap_pbase64decode_strict() adds to the functionality of
ap_pbase64decode() in two ways:
- the length of the decoded buffer is returned, allowing embedded NULLs
to be retained by the caller
- the input string is strictly checked for Base64 validity, including
correct zero-padding at the end of the string
