Python: Ignore 'Incorrect padding' error when base64 decoding
I have some data that is base64 encoded that I want to convert back to binary even if there is a padding error in it. If I use base64.decodestring(b64_string) it raises an 'Incorrect padding' error.

Flash to PHP base64 encode/decode
I'm using AS3 to base64 encode a JPG and pass it to Javascript. I'm attempting to use AJAX to pass that base64 encoded string to PHP and have PHP decode it.

How do I encode something in PHP with a key?
I see base64_encode can encode values, but without a key. I need a function that takes a salt and data, encodes it, and can be decoded with the same salt (but if you try to decode it without the salt, it gives you gibberish). Is there a PHP function for this (can't find it, only modified versions of base64_encode). EDIT: Found the answ...
R: serialize base64 encode/decode of text not exactly matching
