What's New in v1.6.0

• 🔐 Recipient keys (ML-KEM-768): optional post-quantum encryption per NIST FIPS 203. New Keys tab to generate / import / share / delete .vctpub (public) and .vctkey (private) key files
• 📨 Encrypt to a public key: on the Encrypt tab, choose a recipient's .vctpub and the password becomes optional - dual-channel files (password OR private key) or key-only files
• 🔓 Unlock with your private key: the Decrypt tab can open recipient-encrypted files with your .vctkey + its protection password
• 🧪 Cross-validated crypto: the ML-KEM-768 implementation is verified against Go's standard library with checked-in KAT vectors; flutter test runs in CI
• All previous features (Secure Notes, decoy/duress, batch, shred, auto-lock, password generator) included

What's New in v1.5.0

• 📝 Secure Notes: encrypt text directly into a .VCT file; decrypted notes stay in memory only (nothing touches disk)
• 📊 Password strength meter: live entropy estimate under every password field
• ⌨️ Desktop shortcuts: Ctrl+1..4 switch tabs, Ctrl+L panic lock (Cmd on macOS)
• 📤 Full-width Share button on every result card - the reliable way to export on iOS/Android
• 🎭 Decoy partition, duress password, secure shred, auto-lock, batch encryption and the file inspector from earlier releases all included

What's New in v1.1.0

• 🔥 Duress Password: entering it during decryption PERMANENTLY destroys the encrypted file (irreversible)
• 🎭 Decoy Partition: a second password decrypts to an innocent decoy file (plausible deniability - every V2 file looks identical whether or not these features are used)
• 🧹 Secure Shred: overwrite the original file with random data after verified encryption
• ⏱️ Auto-Lock: automatically clears entered passwords after inactivity
• 🔒 VCT format v2 (VCTCRYPT2) with 3-way constant-time password verification; v1 files remain fully decryptable
