captcha-generator

Generate large amounts of captchas (in parallel) with a simple binary written in Rust.

Note: It is really FAST. (Generates 1500 captcha per second which is about 12 x faster compared to 125 captchas per second of a previous Numpythonic implementation.)

Usage

Download the binary from the recent release.

Then: bash captcha-generator [number-of-captchas] [path/to/output/dir]

The text of the captcha will be stored in the filename.

Examples

  1. Generate 100 random captchas to a data directory inside your current working directory.

    bash captcha-generator 100 ./data

  2. Generate 1 random captcha to a './data/train' directory inside your current working directory. bash captcha-generator 1 ./data/train produces ./data/train/qgC6z.png
