git-remote-gcrypt is a git remote helper to push and pull from repositories encrypted with GnuPG, using a custom format
Supported backends are local, rsync:// and sftp://, where the repository is stored as a set of files, or instead anywhere gcrypt will store the same representation in a git repository
The aim is to provide confidential, authenticated git storage and collaboration using typical untrusted file hosts or services.
Tested: it works fine and is very easy to setup:
git remote add gitcrypt gcrypt::git@...
git config user.signingkey ...
git config gcrypt.participants ...
git push gitcrypt masterTo encrypt only SOME files in a git repo, better look at git-crypt
This person should be funded in a level that is appropriate for how critical log4j2 is used in the ecosystem. There is no excuse for this. This person's spare time passion project is responsible for half of the internet working the way it should.
TL;DR: If you want me to make you useful software, pay me. If you use software made by others in their spare time and find it useful, pay them. This should not be a controversial opinion. This should not be a new thing. This should already be the state of the world and it is amazingly horrible for us to have the people that make the things that make our software work at all starve and beg for donations.
adversaries can attack the encoding of source code files to inject vulnerabilities
The trick is to use Unicode control characters to reorder tokens in source code at the encoding level.

tl;dr: User countermeasures:
- Noreply-Email-Address: Every GitHub user should either use a dedicated commit email address or GitHub’s noreply-email-address service, also enabling the option to block accidental command line pushes.
- 2-Factor-Authentication: Every GitHub user should have 2-Factor-Authentication enabled
- Raise Awareness: it’s the duty of developers aware of this issue toinform their colleagues about it

Linkback protocols are an old breed. They were born in a time where MySpace, Wikipedia & WordPress had just been born, and Friendster was more popular than this new website called Facebook.
The latest linkback protocol, Webmention, is relatively recent though, as it became a W3C …
Almost a year ago, GitHub introduced security alerts. They are an awesome feature.
They function as notifications you receive whenever a vulnerability affecting one of your project dependencies.
But long after receiving a notification, how to list all security alerts affecting your repositories ?
I didn't found an out-of-the box solution …
Consider the following Python expression:
print("".join(set("ABCDE")))
What do you think it produces ?
Not necessarily "ABCDE". Right, but you would expect the result to be consistent, isn't it ?
$ for i in {1..3}; do python2.7 -c 'print("".join(set("ABCDE")))'; done
