Main features
Encrypted vault
Profiles, saved SSH passwords, and known host keys are protected with scrypt and AES-256-GCM. The master password is never stored on disk.
Server profiles
Save a host or IP, port, user, SSH key, and optional password for repeated connections.
SSH terminal
Interactive terminal with host-key fingerprint verification and DNS, IPv4, and IPv6 connectivity.
Installable plugins
Each tool is a standalone verified package that can be installed, updated, or removed without modifying Core.
Update catalog
Core lists all compatible builds, distinguishes same-version releases by date, and verifies both size and SHA-512. Application updates also require a valid detached OpenPGP signature. License acceptance is required again for every new build.
Three languages
The app and website support Czech, German, and English with automatic environment-based selection.
Hash & Checksum
A built-in local tool in the left sidebar below Plugins. It provides 49 algorithms, HEX/Base64, verification, file comparison, and checksum manifests in Czech, German, and English.
Server Diagnostics
Probe ICMP, traceroute, DNS, HTTP/1.1/2/3, TLS and TCP without an SSH connection. Live results, local history and JSON/CSV/TXT exports.
Technical reference
SHAKE and KangarooTwelve have configurable output lengths of 16–1024 bytes; SHAKE128, SHAKE256, and KangarooTwelve default to 32, 64, and 32 bytes. xxHash and MurmurHash3 support seeds; SipHash and HighwayHash support HEX keys. A blank key field uses an all-zero key. BLAKE3 has a fixed 256-bit output.
