Hello! I have created this dataset that consists of captcha png's and their SHA-1 solutions within the name of the image to help people that want to learn AI have an interesting "challenge" to solve.

I might add more captcha types with their solutions in the future

This dataset has captcha png's with the file naming in this format: cap_sha1.png, so the file cap_0004cd3f56246ad7396b8509455cad4bc860dbae.png would have a solution that when hashed as SHA-1 returns 0004cd3f56246ad7396b8509455cad4bc860dbae

For example, here is cap_0004cd3f56246ad7396b8509455cad4bc860dbae.png

When solved manually, the answer is 2ra15

The SHA-1 hash for this image as stated in the name is 0004cd3f56246ad7396b8509455cad4bc860dbae

Trying to convert the answer to SHA-1 using either code or in this example this website: You can see that the solution's SHA-1 matches with the captcha's filename
