Generate Captcha Using Python

Last Updated : 08 Oct, 2021

In this article, we are going to see how to generate a captcha using Python package captcha to generate our own CAPTCHA (Completely Automated Public Turing Test to Tell Computers and Humans Apart) in picture form. CAPTCHA is a form of challenge-response authentication security mechanism. CAPTCHA prevents automated systems from reading the distorted characters in the picture.

Installation:

pip install captcha

Generating image captcha:

Here we are going to generate an image captcha:

Stepwise implementation:

Step 1: Import module and create an instance of ImageCaptcha().

image = ImageCaptcha(width = 280, height = 90)

Step 2: Create image object with image.generate(CAPTCHA_Text).

data = image.generate(captcha_text)

Step 3: Save the image to a file image.write().

image.write(captcha_text, 'CAPTCHA.png')

Below is the full implementation:

Python3

# Import the following modules
from captcha.image import ImageCaptcha
 
# Create an image instance of the given size
image = ImageCaptcha(width = 280, height = 90)
 
# Image captcha text
captcha_text = 'GeeksforGeeks' 
 
# generate the image of the given text
data = image.generate(captcha_text)  
 
# write the image on the given file and save it
image.write(captcha_text, 'CAPTCHA.png')

Output:

Image CAPTCHA

Generating Audio captcha:

Here we are going to generate an audio captcha:

Stepwise implementation:

Step 1: Import module and create an instance of AudioCaptcha().

image = audioCaptcha(width = 280, height = 90)

Step 2: Create an audio object with audio.generate(CAPTCHA_Text).

data = audio.generate(captcha_text)

Step 3: Save the image to file audio.write().

audio.write(captcha_text, audio_file)

Below is the full implementation:

Python3

# Import the following modules
from captcha.audio import AudioCaptcha
 
# Create an audio instance
audio = AudioCaptcha()  
 
# Audio captcha text
captcha_text = "5454"
 
# generate the audio of the given text
audio_data = audio.generate(captcha_text)
 
# Give the name of the audio file
audio_file = "audio"+captcha_text+'.wav'
 
# Finally write the audio file and save it
audio.write(captcha_text, audio_file)

Output:
