Self-Hosted mTLS Certificate Manager for Families
A lightweight, self-hostable web application that simplifies the issuance, rotation, and revocation of client certificates for family devices. It provides a simple mobile-friendly portal for family members to install and trust certs, while giving the admin one-click revocation capabilities.
これが重要な理由
You run a secure homelab and want to lock down your exposed services with mutual TLS. But the moment you try to roll out client certificates to your partner or kids, you hit a wall. Manually generating certs, transferring them to family phones, and trusting the root CA is a nightmare. When a phone is lost, revoking access requires fiddling with CRLs. Existing tools are either enterprise-grade behemoths or fragmented CLI scripts. You wish there was a simple, self-hosted web app that handled the entire lifecycle, from easy mobile installation to one-click revocation, without requiring a PhD in PKI.

自己反論 — 最も重要な信頼のシグナル
- 1Mobile OS restrictions may make programmatic certificate installation and root CA trust too difficult to achieve a seamless user experience.
- 2The target audience of self-hosters is notoriously frugal and may simply stick with manual scripts or SSO alternatives rather than paying a monthly fee.
- 3Security implications of hosting your own CA management tool may deter privacy-conscious users who fear a compromise of the management dashboard.
エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
Approximately 5 commenters discussed the difficulties of managing mTLS for family devices. Users explicitly stated that mTLS is a pain to maintain on family phones and highlighted the annoying aspects of cert lifecycle, particularly rotation and revocation. While tools like PocketID and VaultLS were mentioned as partial solutions, the consensus was that no easy, automated path exists for provisioning and revoking certs on non-technical family members' devices. The original poster was actively researching CRLs for revocation, underscoring the unmet need.
