ENCRYPTION GUARANTEES

AESUS CRYPTOGRAPHY

Fur uses AESus (AES + us) — a memory-hard encryption library built in Rust, combining Argon2id key derivation with AES-256-GCM authenticated encryption.

NON-DETERMINISTIC

Same plaintext produces different ciphertext each time. Random nonces and salts prevent pattern detection.

AUTHENTICATED ENCRYPTION

AES-256-GCM provides confidentiality and integrity.

EVERYTHING PROTECTED

Metadata, IDs, ordering, content, attachments — all encrypted together.

GIT COMPATIBLE

Encrypted conversations can be safely stored in public Git repos.

WORKFLOW EXAMPLE

# Create a project
$ mkdir research && cd research
$ fur new "GPT-5 Experiments"
# Add conversations
$ fur jot "Symbolic regression with KAN"
$ fur chat gpt-5
$ fur jot "Derivations" --file derivations.md
# Explore & search
$ fur timeline
$ fur tree
$ fur search "universal approximator"
# Secure your data
$ fur lock
$ git add -A && git commit -m "Add research notes"
$ git push origin main
# Later: restore anywhere
$ fur unlock
$ fur printed
Fur Safe - Encrypted diary vault with electronic security

THE FUR SAFE

A companion project demonstrating encryption in action. The Fur Safe is a public Git repository with password-protected conversations stored as encrypted artifacts.

Key insight: Conversations remain completely private even when their encrypted artifacts live in a public repository. Perfect for version control, backup, and reproducible demonstrations.

EXPLORE THE SAFE

The Fur Safe demonstrates how encrypted conversations behave under Git version control without exposing any plaintext.
