Step 4 and 5: You can convert the normal Base64-encoded Python string back to the hex string from the beginning by using the string.encode() method to obtain a bytes object, passing it into the base64.b64decode() function to obtain a Base64 bytes representation, and converting it to a hexadecimal string by using the bytes.hex() method. Voilà, exactly what you wanted! But how to convert it back? Step 3: To convert the bytes object in Base64 encoding to a normal Python string, we use the code() method. For example, Python has a base64 module to support these encodings and decoding, which can be easily used as below. It is also used to embed images into websites. It converts documents with 8bit data such as emails to ASCII code. This is almost what you want - but it’s not yet a normal Python string! > base64.b64encode(omhex(s)) Base64 is one of the major encoding schemes of data. Step 2: You use the base64.b64encode() function to take the hex string (as bytes object) and convert it to a bytes object in Base64 encoding. We require it to be a bytes object because this is the required input format of the base64 functions shown in a moment. Step 1: The initial hex string is still in a non-standardized format '02af01ff00'. You can see that the start and end values of the conversion remain the same. The output shows that you successfully converte from the hex string to the Base64 string and back to the hex string: 02af01ff00 Here’s a code example-I’ll break it down for you right after the code: import base64ī64 = base64.b64encode(omhex(s)).decode() You can convert the resulting Base64 string back to a normal string by using the one-liner expression: You can convert a hex string of the format '02af01ff00' to a Base64 encoded normal Python string by using the expression:īase64.b64encode(omhex(s)).decode() □ Recommended Tutorial: Python Base64 – String Encoding and Decoding How to Convert Base64 Encoding (Hex String) to Human-Readable String in Python? my script includes this line: encoded 'Basic ' + s.encode ('base64').rstrip () But gives me back the error: LookupError: 'base64' is not a text encoding use codecs.encode () to handle arbitrary codecs This line seemed to work fine in python 2 but since switching to 3 I get the error python python-3. (And, no, Emojis don’t have any place in Base64, it’s VERY old school!) Index Here’s the whole table - fortunately, the encoding is small and efficient enough that I can show you the whole thing! □ Each bit position doubles the number of different encodings, so the Base64 encoding can encode 2*2*2*2*2*2 = 2^6 = 64 different characters. □ What Is Base64 Encoding?īase64 is a very minimal encoding where a minimal set of characters - A-Z, a-z, and 0-9, essentially - are encoded using only six bits. You may already know about Base64 - in that case, I’d recommend you skip the next section and jump ahead right away. Python’s Base64 module provides functions to encode binary data to Base64 encoded format and decode such encodings back to binary data. Although I studied computer science a couple of years ago, I don’t have all those super basic “bits” of knowledge at the top of my head all the time. In PHP 7, the padding issue with base64decode() is no more - the following is. First, you need to import the base64 library: import base64. In this section, we’ll focus on how to encode binary data using the base64 library. If you’re like me, you may need a quick refresher on how Base64 encoding works and what it is exactly. Base64-encoded data takes about 33 more space than the original data. Python comes with a built-in library called base64 that provides various functions to perform Base64 encoding and decoding. The win-unicode-console package is designed to solve your encoding issues while you run Python from the Windows console. □ Short answer: Use the following fancy one-liner expression to convert the hex string s to a Base64-encoded Python string: base64.b64encode(omhex(s)).decode().
