# Algorithm implementations used by the `hashlib` module.
|
||
|
|
|
||
|
|
This code comes from the
|
||
|
|
[HACL\*](https://github.com/hacl-star/hacl-star/) project.
|
||
|
|
|
||
|
|
HACL\* is a cryptographic library that has been formally verified for memory
|
||
|
|
safety, functional correctness, and secret independence.
|
||
|
|
|
||
|
|
## Updating HACL*
|
||
|
|
|
||
|
|
Use the `refresh.sh` script in this directory to pull in a new upstream code
|
||
|
|
version. The upstream git hash used for the most recent code pull is recorded
|
||
|
|
in the script. Modify the script as needed to bring in more if changes are
|
||
|
|
needed based on upstream code refactoring.
|
||
|
|
|
||
|
|
Never manually edit HACL\* files. Always add transformation shell code to the
|
||
|
|
`refresh.sh` script to perform any necessary edits. If there are serious code
|
||
|
|
changes needed, work with the upstream repository.
