esptool Python module is a collection of libs and scripts to interact with the bootloader on Espressif SoCs. The Python module happens to provide three useful scripts: esptool, espefuse and espsecure. esptool is the backbone of communication with the Espressif SoC's bootloader. espefuse is useful when one needs to burn fuses or read the current fuse state. Finally, espsecure is a tool for setting up Espressif implementation of secure boot on their SoC. espsecure depends on python3-cryptography which is a Rust-based Python module, making it a heavy tool dependency-wise which is the reason why the scripts have been split in their own package so that people only interested in esptool script have the smallest possible dependency chain.
