历史

项目历史与用法

showcert is a Python command-line package containing `showcert` for reading and checking local or remote X.509 certificates and `gencert` for creating development certificates.

项目历史

showcert was created as a human-oriented front end for routine X.509 work. The project separates read-oriented operations into `showcert` and development certificate creation into `gencert`.

The project deliberately targets common certificate tasks rather than the full breadth of OpenSSL. Its documentation warns that certificates generated by `gencert` are intended for development rather than production.

采用历史

The official README documents installation with pipx, while the supplied package facts record Homebrew and Fedora/DNF packaging. This gives the Python utility both language-oriented and operating-system package routes.

使用方式

`showcert` accepts certificate files, standard input, hostnames, or hostname-and-port targets. It can display certificate chains, save PEM output, check names and expiration, and negotiate STARTTLS for SMTP, POP3, and IMAP.

`gencert` creates self-signed certificates or a small development CA and CA-signed certificates. It writes certificate and private-key files selected by command options; these are outputs, not a persistent credentials-file convention.

为什么软件包爱好者会关心

showcert packages common OpenSSL certificate-inspection pipelines into memorable commands and structured exit statuses. It is attractive for workstation checks, lightweight monitoring scripts, and development PKI tasks where direct OpenSSL invocations are unnecessarily cumbersome.

时间线

Project lifetime: The official repository accumulated a focused implementation and command reference for the showcert and gencert utilities.
Current packaging: The project documents pipx installation and is also represented in Homebrew and Fedora/DNF metadata.

Related projects

OpenSSL supplies the lower-level certificate operations whose routine command sequences showcert aims to simplify.
Let's Encrypt and Certbot deployments receive dedicated handling through the `:le` input alias.
