CertGuard

A Terminal User Interface (TUI) for inspecting Certificate Revocation Lists (CRL's)

With CertGuard it is currently possible to:

• download new CRL files to the local cache directory
• browse locally downloaded CRL files
• inspect entries in a CRL file

File locations

CertGuard uses two file locations:

• ~/.cache/certguard for the file cache where CRL files are stored
• ~/.local/share/certguard for the debug.log file

States

CertGuard TUI is built with BubbleTea using the Elm architecture. Different screens are built using different states. Below is a statemachine depicting the state model of CertGuard:

Development

A MAKE file has been included for convenience:

• make run builds and run the certguard application in debug mode
• make test runs all unit tests
• make lint runs the linter
• make build builds the binary file cg

Since a TUI application cannot log to stdout a debug.log file is used for debug logging. It is located at: ~/.local/share/certguard/debug.log
