Introduction
In this tutorial we learn how to install cvm on Kali Linux.
What is cvm
cvm is:
CVM is a framework for validating a set of credentials against a database
using a filter program. The modules act as a filter, taking a set of
credentials as input and writing a set of facts as output if those
credentials are valid. Optional input is given to the module through
environment variables.
Some of the ideas for CVM came from experience with PAM (pluggable
authentication modules), the checkpassword interface used by qmail-pop3d,
and the “authmod” interface used by Courier IMAP and POP3. This framework
places fewer restrictions on the invoking client than checkpassword does,
and is much simpler to implement on both sides than PAM and the authmod
framework.
This package includes cvm binaries.
