Base64 coding refers to encoding data from binary to text. This translates binary data to a radix-64 format in order to represent binary data in an ASCII string format.
There are many methods that are part of the Python
base64.a85decode is one of the methods of the base64 library. We use
a85decode to decode an a85encoded binary string into its normal form using Ascii85 alphabets.
base64.a85decode(b, foldspaces=False, adobe=False, ignorechars=b'\t\n\r\v')
b: A bytes-like object.
True, the 4 consecutive spaces will be replaced by a character
True, the encoded string is written in between
ignorechars: The characters to be ignored in the encoding process.
The parameters do not have a significant impact when
import base64 # Data data = "Welcome to Educative" print("data:", data) # converting the data to bytes-form data_bytes = data.encode("UTF-8") # perform the a85 encode function result = base64.a85encode(data_bytes) # set adobe to True result1 = base64.a85encode(data_bytes, adobe = True) print("a85encoded: ", result) print("with adobe", result1) ## We can use a85decode function to decode. # reverse of string with adobe set to False. result2 = base64.a85decode(result) print("a85decoded: ", result2) # reverse of string with adobe set to True. result3 = base64.a85decode(result1, adobe = True) print("a85decoded: ", result3)
