base64 string to byte array python

 

 

 

 

I am using Python 2.7 to decode base64 data and I dont understand why base64.b64decode returns a string? How do I get to the binary data that is decoded? I would think base64.b64decode would return a byte array. The modern interface, which was introduced in Python 2.4, providesThis allows an application to e.g. generate URL or filesystem safe Base64 strings. The default is None, for which the standard Base64 alphabet is used. The following example uses the ToBase64String(Byte[]) method to convert a byte array to a UUencoded (base-64) string, and then calls the FromBase64 String(String) method to restore the original byte array. str data (also called bytes data or ASCII data). This is immutable (cannot be modified). bytearray data like str but it is mutable (changeable).Final encoding string is /8. is added for padding.

Possibly the binascii module and struct can be helpful, too. Import binascii import struct. Binstrb"thisisunreadablebytes". Encodedbinascii.

b2a base64(binstr) print encoded print binascii.a2bbase64(encoded). The bytes type in Python is immutable and stores a sequence of values ranging from 0-255 (8-bits). You can get the value of a single byte by using an index like an array, but the values can not be Cast bytearray back to bytes immutablebytes bytes(mutablebytes) print(immutable bytes). I feel like I have exhausted every resource online trying to find a routine to decode a Base64 encoded String. I need a method I can pass a String to and have it return something like an unsiged char[] or other form of byte array.
