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

With CertGuard it is currently possible to:

• download & save new CRL files to the local storage
• import locally downloaded CRL files to the local storage
• browse stored CRL's
• list entries in a CRL file
• inspect entries in a CRL file

CertGuard uses two file locations:

• ~/.cache/certguard location of the database/storage file
• ~/.cache/certguard/import import directory for importing CRLs from file
• ~/.local/share/certguard for the debug.log file

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:

All information on CRL's and revoked certificates are stored on a local SQLite database. The Database schema used for Certguard only stores public information:

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
• make sqlc generates the Go source files from SQL files using sqlc
• make gif generates the gif based on the cassette.tape using vhs

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
