Git credential helpers
======================

Published: June 30, 2025

Git credential helpers work via writing and reading from standard input and standard output which helped me debug an issue I was having with pass-git-helper. To get a credential helper to spit out the password, invoke it with the get action and pass in some basic key=value data. The interaction looks somewhat like given below, with < indicating the standard input of the credential helper and > indicating its standard output.
