Encrypt folders with AES-256.

• Linux
• Raspberry Pi

Lock any folder into a strong AES-256 encrypted container — it verifies before removing originals, so nothing is ever lost.

What it does

• Encrypts an entire folder into a single locked .flock container with AES-256-GCM
• Memory-hard scrypt key derivation from your password — no key files to lose
• Streamed per-chunk encryption, so even very large folders use little memory
• Verifies the container fully decrypts before the original folder is ever deleted — no data loss
• Password-strength rules plus failed-attempt lockout with a cooldown
• Works offline; bilingual Arabic/English interface — the internet is used once to activate your licence
