In their own words
KeyTalk CKMS
KeyTalk CKMS automates PKI implementation and the enrollment, distribution and management of digital certificates. It keeps certificates and keys in a central repository and supports automated or semi-automated deployment and renewal, alongside reporting, notifications and alerts. Smart Security Scan finds certificates and keys on a network so valid findings can be imported. The product includes a private certificate authority that can operate beneath an existing root or as a standalone root. Integrations and protocols include DigiCert, DigiCert QuoVadis, GlobalSign, Microsoft CA, Intune, MobileIron, load balancers, HSMs, Citrix, SCEP and ACME. Access controls include AD and Entra ID authorization, multifactor authentication and role-based controls. CKMS can run as a virtual machine on customer infrastructure, in private cloud environments such as AWS, Azure and Google Cloud, or as KeyTalk-managed PKI service. General CKMS pricing is on request, and a free trial is available. Separate S/MIME plans cost €5 a month for on-premise service and €6.50 a month for hosted SaaS, billed per user per month.
lego
lego is an independent, free, open-source ACME client and Go library for obtaining, renewing, and revoking certificates. It supports wildcard and SAN certificates and can work with multiple ACME servers, including Let’s Encrypt and ZeroSSL. Validation choices include DNS-01, HTTP-01, TLS-ALPN-01, and DNS-PERSIST-01. The project lists more than 200 DNS providers, including Cloudflare, Amazon Route 53, Google Cloud DNS, and Azure DNS, with CNAME support enabled by default. Users can run lego from the command line or call it as a Go library. DNS credentials and settings are supplied through environment variables, with file references and dotenv files supported. Installation options include prebuilt binaries, Docker, package managers, and source. The maintainers look after the AUR and Snap packages; other listed packages are community maintained. The project lists support for ACME RFC 8555 and certificate validation and renewal extensions. It is licensed under MIT, and installing from source requires Go 1.25 or later. The project points to GitHub issues and discussions for help.
