#PYTHON BASE64 DECODE PDF#
Therefore, if you get Base64 from an untrusted source, you must sanitize the PDF contents by removing all active content (such as JavaScript, actions, embedded files).įull working example (please note that this example was tested only in Python 3.7.
#PYTHON BASE64 DECODE HOW TO#
Below I want to show you a basic example of how to do this, but before continuing I want to warn you that PDF files may contain malicious content that may jeopardize the security of users viewing such PDF files. To convert Base64 to PDF file in Python you need the base64.b64decode function and any function to write binary data into local files. Guru A virtual teacher who reveals to you the great secrets of Base64 Now these functions accept any bytes-like object (opens new window).Base64. Up until Python 3.4 came out, base64 encoding and decoding functions only worked with bytes or bytearray types. If adobe is True, the encoded sequened with be framed with '' as used with Adobe productsīase64.a85decode(b, foldspaces=False, adobe=False, ignorechars=b'\t\n\r\v')Ī bytes-like object of characters to ignore in the encoding process If pad is True, the bytes are padded to a multiple of 4 before encoding The number characters before a newline (0 implies no newlines) If foldspaces is True, the character 'y' will be used instead of 4 consecutive spaces. If valide is True, the characters not in the normal Base64 alphabet or the alternative alphabet are not discarded before the padding checkīase64.a85encode(b, foldspaces=False, wrapcol=0, pad=False, adobe=False) Extra characters are ignored.īase64.b64decode(s, altchars=None, validate=False)
