In Python 3, you need to encode it in ASCII first, so you'll have to do: The base64.b64decode () function takes a byte string as the argument. Base64 converts text data into binary data. Once converted, we can use the base64 module to encode it. If you do link to such a site, you must disclose that it's your site.If you don't disclose affiliation, it's considered spam. Input is case-insensitive. Example #1 : In this example we can see that by using base64.b64encode () method, we are able to get the encoded string which can be in binary form by using this method. Default encoding is the current default string encoding. With the help of base64.urlsafe_b64encode (s) method, we can encode the string using url and file system safe alphabets into the binary form. binhex (input, output) ¶. base64.b64encode: "Encode the bytes-like object s using Base64 and return the encoded bytes." To encode binaries ... Encode files to Base64 format Select a file to upload and process, then you can download the encoded result. The name "uuencoding" is derived from Unix-to-Unix Copy, i.e. This module encodes and decodes files in binhex4 format, a format allowing representation of Macintosh files in ASCII. Using Python to decode strings: Decoding Base64 string is exactly opposite to that of encoding. Syntax : base64.b64decode (b_string) Return : Return the decoded string. Download the file for your platform. Since + and / characters are not URL and filename safe, The RFC 3548 defines another variant of Base64 encoding whose output is URL and Filename safe. It provides encoding and decoding functions for the encodings specified in RFC 4648, which defines the Base16, Base32, and Base64 algorithms, and for the de-facto standard Ascii85 and Base85 encodings. Python 3 - String encode() Method, The encode() method returns an encoded version of the string. The drawback of base64 encoding is that it renders the text non-human readable.

This is a good encoding to use when most of your payload is unprintable data since it is a more compact form than quoted-printable. More precisely, it is an encoding of binary data in a sequence of printable characters. Only the data fork is handled. First, we import the base64 module into our Python script.. Once we have done so, we define a function, get_base64_encoded_image, that takes an image path as the parameter. Have a look at the Python program given below.
