: Supports using any external file as a secondary authentication factor alongside your password. No Installation Required
(Password read from terminal without echo; support for reading from env or file descriptor.)
Unlike complex suites, Picocrypt focuses on doing one thing exceptionally well: encrypting individual files and folders with zero bloat. Its name—"Pico"—reflects its tiny footprint, yet it packs industry-leading security under the hood.
For environments demanding absolute data isolation, "Paranoid Mode" introduces cascaded encryption. When enabled, data is double-encrypted using both and the Serpent block cipher. Furthermore, it elevates the authentication protocol from BLAKE2b to HMAC-SHA3 , establishing a multi-layered defense designed to withstand unforeseen algorithmic breakthroughs.

Type a strong passphrase (e.g., 5 random diceware words). Picocrypt will show a strength meter.
: Picocrypt provides a secure way to protect your files from unauthorized access, using strong encryption algorithms.
Picocrypt is built to be used anywhere without installation, making it ideal for "portable" security on thumb drives. : Fully supported on Windows, Linux, and macOS. : Supports using any external file as a
, a high-speed stream cipher that provides a 192-bit nonce, making it extremely resistant to nonce-reuse attacks compared to standard AES-GCM. Key Derivation
One common critique of Picocrypt is that it is too simple. "Where are the key stretching iterations?" "Where is the plausible deniability?"
: Perfect for encrypting sensitive files before putting them on a flash drive that might get lost. Cloud Archiving Reed-Solomon Error Correction Type a strong passphrase (e
: A unique "paranoid mode" feature that adds redundant data to files, allowing them to be recovered even if the encrypted volume suffers minor data corruption (e.g., from bit rot on a USB drive). The "State of the Union": Development Status
To prevent chosen-ciphertext attacks and file tampering, Picocrypt applies authenticated encryption. By default, it hashes data blocks using the highly efficient algorithm. During decryption, the software verifies this cryptographic signature first. If an attacker alters even a single bit of the encrypted volume, Picocrypt halts execution and safely deletes the corrupted payload to prevent information leaks. Advanced Toolsets for Power Users
