# Haketilo Software Bill of Materials

[Software Bill of Materials (SBOM)](https://en.wikipedia.org/wiki/Software_bill_of_materials) lists external components used or included in a given software product. 

You may also want to look at the [SBOM of Hydrilla](/projects/hydrilla/wiki/Hydrilla_Software_Bill_of_Materials) and [a concatenated plain text version](https://hydrillabugs.koszko.org/attachments/download/106/SBoM_haketilo-1.0_hydrilla-1.0.txt).

*Note: This SBOM corresponds to the upcoming Haketilo version 1.0.*

### js-sha256

| field        | value                                           |

|--------------+-------------------------------------------------|

| upstream url | https://github.com/emn178/js-sha256             |

This JavaScript implementation of SHA256 is included in the browser extension itself. It is used to derive nonces used internally by Haketilo. This library is only used in contexts where synchronous computation of SHA256 digest is required. In other cases (e.g. verification of integrity of downloaded files), the asynchronous `crypto.subtle` JavaScript API is used.

## External dependencies

### POSIX environment

Standard UNIX tools (sh, awk, etc.) are needed to **build** Haketilo. There's no known dependency on specific implementations of those (e.g. gawk should work just as well as nawk).

### Make

Make build system is an **optional requirement for building** Haketilo and a **strict requirement for running the test suite**. There's no known dependency on specific Make implementation.

### Python3

Python in at least version 3.7 is needed to run the automated test suite.
