"AESus v", env!("CARGO_PKG_VERSION"), r#"
A lean, unforgiving encryption tool forged in Rust and irony.
AESus transmutes human-readable Diceware passphrases into cryptographic
keys and seals data using AES-256-GCM. Salt, nonce, and ciphertext are
packed into a single binary blob like cursed runes for your future self.
Whether you're encrypting files or whispering secrets into the void,
AESus ensures only the correct passphrase can bring them back.
☠️ Features ☠️
- Argon2id key derivation (128MB memory, 3 iterations)
- AES-256-GCM authenticated encryption
- Secure random salt and nonce generation
- Diceware-style passphrase generation
- File encryption/decryption with `.aesus` suffix
- Absolutely zero forgiveness
🕯️ Remember your passphrase.
🕯️ Fear the corrupted file.
🕯️ Encrypt with style. Decrypt with repentance.
⚙️ Usage Examples ⚙️
# Encrypt a string
$ aesus encrypt "hello world" \
--key orbit-lunar-toast-vapor-cactus-dynamo
# Decrypt a hex-encoded string
$ aesus decrypt \
--hex 6654259...27d4de40c \
--key orbit-lunar-toast-vapor-cactus-dynamo
# Encrypt a file
$ aesus encrypt \
--file ./secret.txt \
--key lemon-magic-vapor-cactus-dynamo-forest
# Decrypt a file
$ aesus decrypt \
--file ./secret.txt.aesus \
--key lemon-magic-vapor-cactus-dynamo-forest
# Generate a Diceware passphrase
$ aesus generate --words 7
⚠️ Security note:
Use at least 6 Diceware words (≈77 bits entropy).
Shorter passphrases may be vulnerable to offline cracking.
