Applied cryptography notes, PGP tools, Templar cipher references and modern encryption practices. This repository is a living notebook of how I actually use encryption in day‑to‑day work: generating and managing keys, encrypting files and messages, and integrating modern tools into an off‑grid communication stack.
- Practical notes on OpenPGP / GnuPG usage
- Key management workflows (backup, revocation, subkeys)
- File and message encryption with modern tools (age, minisign, etc.)
- References to historical ciphers (e.g. Templar cipher) and their modern reinterpretations
- Shell scripts and snippets that tie these tools into everyday use
This is not a cryptography textbook.
The focus here is:
- applied, real workflows that can be used today
- tools that run well on Unix‑like systems and low‑power hardware
- patterns that integrate cleanly with decentralised communication (Reticulum, NomadNet, LXMF, Meshtastic, etc.)
When in doubt, preference goes to simplicity, auditability and long‑term survivability of keys and data.
CypherTools is a personal reference that evolves over time as tools and practices change.
Expect incremental updates rather than big versioned releases.
