Anyone who has gone through the trouble of setting up a secure website knows what a hassle getting and maintaining a certificate can be. Let’s Encrypt automates away the pain and lets site operators turn on and manage HTTPS with simple commands.




PQ-Sign is described as 'Post-quantum signing API built on ML-DSA-65 (NIST FIPS 204) — sign tokens, issue certificates, and verify signatures without managing cryptographic infrastructure' and is an app in the security & privacy category. There are five alternatives to PQ-Sign for a variety of platforms, including Self-Hosted, Cloudron, Linux, Web-based and BSD apps. The best PQ-Sign alternative is Let's Encrypt, which is both free and Open Source. Other great apps like PQ-Sign are Keycloak, OpenSSL, Vault by HashiCorp and Auth0.

Open Source Identity and Access Management for modern Applications and Services.




OpenSSL is a framework which implements the secure socket layer. It ships with a program/library which gives you access to all those functions.

This solution manages secrets by providing secure storage, encryption, and integration with trusted identities. It automates password rotations, facilitates secure secret injection into apps, and handles encryption key lifecycles, securing data in untrusted systems for robust protection.


You can connect any application (written in any language or on any stack) to Auth0 and define its Connection, the method used to authenticate the users of that application:
