Toolkit release notes
What is new in each aethercert Toolkit release: Windows certificate store, CSR keys in the Windows key store, guided workflows, certificate scanner and security scan.
The toolkit does not update itself. Download a new version from the overview and run its installer; it replaces the installed version and keeps your settings.
1.1.2 - 2026-10-27
Installers
- The desktop app now installs from a signed MSI, for Windows 11 and Windows Server 2019, 2022 and 2025, with English or German setup dialogs.
- Two variants: the installer downloads the Microsoft Edge WebView2 runtime during setup
when Windows has none; the offline installer carries it, for servers without internet
access.
msiexec /i <file> /qninstalls silently. - The portable
.exeand the zip are no longer published.actkstays a single.exe.
Desktop app
- Rebuilt on the same core with the components of the aethercert dashboard: the certificate list, the details panel, forms, dialogs and settings look and work like their dashboard counterparts.
- Create CSR creates the key in the Windows key store of this user or this computer, the
way
certreqdoes; the key never exists in a file or in the app. Importing the issued certificate links it to that key. - Guided steps for Create CSR, Import, Sign code and Convert files; Import is a page of its own and never installs a root certificate.
- Certificate details - names, key, extensions, fingerprints - for the store, scan results, imports and converted files.
- The security scan gives remediation advice for every finding.
- Settings now live in
%APPDATA%\com.aethercert.toolkit\settings.json. Settings and open certificate requests from 0.1.1 are not carried over.
0.1.1 - 2026-10-26
The first release published for download, for Windows x64.
Certificates (Windows certificate store)
- The personal certificates of the current user and of the computer in two tabs, with search, filters, sortable and resizable columns, a status column, weak key and signature flags, and a details panel with copy buttons.
- New CSR from this certificate for renewal or rekey, always with a new key.
- Export to
.pfx,.cer,.crt, full chain, chain only and.keyin one step, with presets for Windows / IIS / Exchange, nginx / Apache / HAProxy and "certificate only". A written.keyis encrypted by default. - Import as a guided page: the issued certificate (
.cer,.crt,.pem,.p7b) finds its key from Create CSR by itself;.pfxworks too. Intermediates go to Intermediate Certification Authorities, roots are never installed. - The computer store is read-only until Restart as administrator.
Create CSR
- Server (TLS), user (S/MIME, client authentication, optional UPN) and code signing requests, or self-signed certificates.
- The private key is created in the Windows key store by default (Microsoft Software Key
Storage Provider, this user or this computer), like
certreq- optionally non-exportable. A.keyfile remains available for servers that take PEM files. - Host names and IP addresses as separate, validated entries, with this computer's addresses as suggestions.
- Field checks the way CAs apply them, and the equivalent OpenSSL command.
- Leaving with a key that exists only in memory asks first.
Check CSR, Convert files, Sign code
- Check CSR decodes any request and lists what a CA would reject.
- Convert files builds a PFX from certificate, chain and key, or takes a certificate or PFX apart; AES-256 or 3DES for Windows Server 2016 and older.
- Sign code Authenticode-signs exe, dll, sys, msi, cab, cat, PowerShell and Windows Script files with an RFC 3161 timestamp, from the Windows store (including USB tokens and HSMs) or a PFX, and reports success only after Windows verified each signature.
Certificate scanner and security scan
- The scanner sweeps hosts, CIDR networks up to
/16and ranges on any ports, with STARTTLS and RDP, this computer's networks as suggested targets, a duration estimate and the time left. Filters for expired, expiring, untrusted, self-signed, name mismatch and no TLS. Export as CSV or JSON. - The security scan grades one endpoint A+ to F with the aethercert.com rubric, with remediation advice for every finding.
Desktop app
- Guided workflows with a step list for Create CSR, Import, Sign code and Convert files.
- English and German, light and dark, a sidebar that collapses to icons on narrow windows.
- The
actkcommand line with the same tools.
