FireDaemon OpenSSL Installer

A very small, very simple, yet very secure encryption tool.

This application is intended for creating and managing X.509 certificates, certificate requests, RSA, DSA and EC private keys, Smartcards and CRLs.

Encrypt files, folders, and text with strong algorithms. Includes steganography and post-quantum key exchange (ML-KEM).

File Encryption, Folder Encryption Software

A filesystem in userspace (FUSE) with transparent encryption (when writing) and decryption (when reading).

A Swiss army knife for working with X.509 certificates, JWTs, etc.

Fetch a public verification key from a JWKS endpoint (or via OIDC discovery) and emit it as PEM.

Offline JWT decoder and (optional) signature verifier — single native exe, no runtime needed.

Signing tools secifically designed for Windows typically use CNG KSP providers. Install and use the SignPath KSP provider to use these tools with SignPath.
