Decoding Strings with Base64 through Python: Finally, we have used the print() function to display the decoded string value. Then we take that encoded value and pass it as a parameter for base64.b64encode() method and then decode it back to ASCII string format.

Next, we create another variable that maps the string conversion type to ASCII (American Code for Information Interchange) format. Then, we will create a variable that stores the normal string. Here, we have to first import the base64 Python module. Print("The Converted value of the string \"", py_string, "\" is" ,base64_string) Syntax: base64.b64encode(string_variable)īase64_string = base64_val.decode('ascii') This method takes a string value as its argument. The b64encode() method of the base64 module helps in converting the string message. Then developers can leverage the base64 module for encoding it. For this, developers have to convert the Python string into a bytes-like object. Python 3 comes with a base64 module that allows developers to quickly and effortlessly encode and decode a string to its equivalent base64 format. Encoding Strings with Base64 through Python: Let us now take a look at how developers use it in Python by converting the string (in Python) to a Base64 string. That table will help in assigning the respective base64 character for each decimal value.

Finally, it will leverage a base64 encoding table.

Next, it converts the 6-bit binary combination to their respective decimal equivalent.

Next, the algorithm transforms the 8-bit chunk into a 6 bits chunk of information by re-clustering its digits.

Next, it will calculate the 8-bit equivalent binary value of the ASCII code.

First, the algorithm will take the ASCII value mapped with each character in the string.

the + and /, for representing new linesįor converting a string to Base64, behind the scene, the following steps take place.

This encoding scheme has 64 characters that help in representing numbers. The name of Base64 encoding has been derived directly from this mathematical definition of bases. In discrete and non-discrete mathematics, the base of a number system signifies how many different characters or elements are used to represent any number. This encoding scheme is not at all related to cryptographic encryption.

When a conversion takes place from Base64 characters to binary, all its characters are represented in 6 bits of information. Define the Base64 Encoding Scheme.īase64 is a type of conversion standard or conversion scheme that turns bytes having binary or text data into ASCII formats or characters.

In this article, you will understand these encoding schemes and how to make them work with simple Python programs. Files that have binary data format or bytes that have non-text information such as images get easily corrupted when transferred and treated by text-only systems.

It means the PDF having images is not readable from the server's end as the file format does not support it. It can happen when your email server was specifically meant or designed to handle text data. If you have ever received any PDF via email and found that some of the texts are non-readable or are difficult to understand its strange characters, due to mixing up with symbols, then do not worry.
