Hardware implementation of the md5 hash function.

Completed. Does Work. Do. Not. Use. (Unless you know what you do.)

The hash function md5 is a broken hash function that shouldn't be used. But sometimes one needs the implementation of a broken hash function anyway...

Do use this to for example break things like password hashes. Do NOT use it to protect anything - password hashes for example.

The core is implemented in Verilog.

This core is supported by the FuseSoC core package manager and build system. Some quick FuseSoC instructions:

install FuseSoC

pip install fusesoc

Create and enter a new workspace

mkdir workspace && cd workspace

Register md5 as a library in the workspace

fusesoc library add md5 /path/to/md5

...if repo is available locally or... ...to get the upstream repo

fusesoc library add md5 https://github.com/secworks/md5

To run lint

fusesoc run --target=lint secworks:crypto:md5

Run tb_md5 testbench

fusesoc run --target=tb_md5 secworks:crypto:md5

Run with modelsim instead of default tool (icarus)

fusesoc run --target=tb_md5 --tool=modelsim secworks:crypto:md5

List all targets

fusesoc core show secworks:crypto:md5
