SSLyze is a fast and powerful SSL/TLS scanning tool and Python library.
SSLyze can analyze the SSL/TLS configuration of a server by connecting to it, in order to ensure that it uses strong encryption settings (certificate, cipher suites, elliptic curves, etc.), and that it is not vulnerable to known TLS attacks (Heartbleed, ROBOT, OpenSSL CCS injection, etc.).
The Mozilla CA certificate store in PEM format (around 200KB uncompressed):

SSL certificate expiry monitoring.
Ensure the continued security and reliability of your website by staying vigilant about SSL certificate expiration.
Lightweight modern Python library to add security headers (CSP, HSTS, etc.) to Django, Flask, FastAPI, and more. Secure defaults or fully customizable.
Just like nip.io or xip.io, traefik.me is a magic domain name that provides
wildcard DNS for any IP address.
Capturing SSL/TLS plaintext without a CA certificate using eBPF. Supported on Linux/Android kernels for amd64/arm64.
Universal identity control plane for distributed systems. SPIFFE and SPIRE provide strongly attested, cryptographic identities to workloads across a wide variety of platforms.
SPIFFE and SPIRE provide a uniform identity control plane across modern and heterogeneous infrastructure. Since software and application architectures have grown substantially, they are spread across virtual machines in public clouds and private data centers. Security models for the organizations that manage them must keep up with these infrastructure technologies. And this is where SPIFFE and SPIRE come in. With SPIFFE/SPIRE, developers and operators can build software using new infrastructure technologies, while allowing security teams to step back from time-consuming security processes.
A local https proxy server using docker as backend.
OpenPubkey is an open source project that binds public keys and workload identities using standard SSO and OpenID Connect.
Use OpenPubkey today to SSH to machines on your network without SSH keys.
Tools to bootstrap CAs, certificate requests, and signed certificates.
A simple certificate manager written in Go, to bootstrap your own certificate authority and public key infrastructure. Adapted from etcd-ca.
All-in-one website OSINT tool for analysing any website. Comprehensive, on-demand open source intelligence for any website.
Get an insight into the inner-workings of a given website: uncover potential attack vectors, analyse server architecture, view security configurations, and learn what technologies a site is using.
Currently the dashboard will show: IP info, SSL chain, DNS records, cookies, headers, domain info, search crawl rules, page map, server location, redirect ledger, open ports, traceroute, DNS security extensions, site performance, trackers, associated hostnames, carbon footprint. Stay tuned, as I'll add more soon!
A simple zero-config tool to make locally trusted development certificates with any names you'd like.
mkcert automatically creates and installs a local CA in the system root store, and generates locally-trusted certificates. mkcert does not automatically configure servers to use the certificates, though, that's up to you.
Minisign is a dead simple tool to sign files and verify signatures.
The Dogtag Certificate System is an enterprise-class open source Certificate Authority (CA). It is a full-featured system, and has been hardened by real-world deployments. It supports all aspects of certificate lifecycle management, including key archival, OCSP and smartcard management, and much more. The Dogtag Certificate System can be downloaded for free and set up in less than an hour.
CFSSL is CloudFlare's PKI/TLS swiss army knife. It is both a command line tool and an HTTP API server for signing, verifying, and bundling TLS certificates. It requires Go 1.16+ to build.
EJBCA covers all your needs – from certificate management, registration and enrollment to certificate validation.
Welcome to EJBCA – the Open Source Certificate Authority. EJBCA is one of the longest running CA software projects, providing time-proven robustness and reliability. EJBCA is platform independent, and can easily be scaled out to match the needs of your PKI requirements, whether you’re setting up a national eID, securing your industrial IoT platform or managing your own internal PKI.
Automatically provision and manage TLS certificates in Kubernetes.
cert-manager adds certificates and certificate issuers as resource types in Kubernetes clusters, and simplifies the process of obtaining, renewing and using those certificates.
It supports issuing certificates from a variety of sources, including Let's Encrypt (ACME), HashiCorp Vault, and Venafi TPP / TLS Protect Cloud, as well as local in-cluster issuance.
cert-manager also ensures certificates remain valid and up to date, attempting to renew certificates at an appropriate time before expiry to reduce the risk of outages and remove toil.
Cloud native certificate management. X.509 certificate management for Kubernetes and OpenShift.
cert-manager creates TLS certificates for workloads in your Kubernetes or OpenShift cluster and renews the certificates before they expire.
