What is base64.a85decode in Python?

Sarvech Qadir

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 module. 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')	 
  1. b: A bytes-like object.

  2. foldspaces: If True, the 4 consecutive spaces will be replaced by a character y.

  3. adobe: If True, the encoded string is written in between <~ and ~>.

  4. ignorechars: The characters to be ignored in the encoding process.

The parameters do not have a significant impact when False.


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)
