Practical tools, libraries and guides for encryption: file, disk, messaging and key management. Use responsibly — security depends on correct usage and OPSEC.
Simple and robust tools to encrypt files and archives for transport or storage.
OpenPGP implementation for encrypting files and emails, signing and key management. Widely used and audited.
A modern, simple and secure file encryption tool. Better UX than complex PGP for one-off file encryption.
Cryptographic toolkit — encryption, TLS, certificates and low-level crypto primitives (use carefully).
Archiver supporting AES-256 encrypted archives (.7z). Useful for quick encrypted bundles (password-based).
Tools for full-disk encryption and protecting volumes on servers or endpoints.
Linux standard for full disk encryption (LUKS). Use strong passphrases and keyfiles where appropriate.
Cross-platform disk container encryption (successor to TrueCrypt). Use for portable encrypted containers.
Encrypt sensitive data before putting into images; use signing and image scanning — do not store secrets in images.
Use battle-tested, audited libs — avoid writing your own crypto.
High-level crypto library (NaCl API) — easy, safe primitives for encryption, signatures, KDFs.
Low-level TLS and crypto primitives. Use with care; prefer higher-level libs for common tasks.
Cryptography libraries in Rust with safe APIs and memory safety advantages.
Guides, specs and references to learn correct cryptographic use.
Guidelines on storing secrets and encryption best practices for apps.
Classic academic material (Stanford / D. Boneh) to understand primitives and protocols.
