File Lock PEA is an encryption application designed to protect individual files and directories. Unlike programs that encrypt an entire disk or create a virtual encrypted drive, it allows users to decrypt selected files temporarily while leaving other protected files inaccessible.
The application is distributed as a Java archive that does not require a conventional installation. It combines authenticated encryption with password-based key derivation and optional keyfiles. File Lock PEA also includes features intended to protect metadata, reduce the risk of leaving files decrypted longer than necessary and support encrypted storage on cloud services. It is particularly suited to users who need to access selected confidential documents rather than unlock an entire encrypted filesystem.
This is free and open source software.
Key Features
- Encrypts files and directories individually, allowing selected items to be decrypted when required.
- Supports authenticated encryption using AES-256, Serpent and Threefish with EAX mode.
- Offers Argon2 and Catena-Dragonfly password-based key derivation functions.
- Supports keyfiles as an additional factor alongside passwords, with keyfile-only operation available.
- Can obscure filenames and other metadata by placing files inside encrypted archives.
- Provides a configurable timer to encrypt files again after a specified period.
- Includes an on-screen keyboard and password strength assessment tools.
- Supports storing encrypted files with cloud storage services without decrypting them during transfer.
