File Lock PEA (PEA = Password Encrypting Archive) encrypts data at the filesystem level and offers the possibility to decrypt single files or whole directories temporarily.
The program consists of a single archive file. Installation is not required.
This is free and open source software.
Key Features
- Files and folders are individually selected for decryption when they are needed.
- Cloud support – save your files in the cloud and upload new versions using several cloud providers. All data remain encrypted during this process.
- Authenticated Encryption – protects the integrity of the data by an authenticated encryption mode. This guarantees that the data has not been manipulated.
- Key File – add a second factor besides the password and protect your data additionally with a key file. Store this key file wherever you want.
- Metadata hiding – many metadata can be masked: File names and other data can be made invisible by encrypting them in zip files.
- Virtual keyboard against Keyloggers – provides an internal on-screen keyboard to protect against hardware keyloggers as well against some software keyloggers.
- Timer to encrypt the files automatically after a certain period of time.
- Uses a memory-hard key derivation function that defends custom-hardware attacks
- Adjustability for colors, font sizes, calendar view.
- Measures the quality of new passwords during input by a password strength meter. Indicates their strength by colored bars.
- Combines System Entropy with its own Entropy Source.
- Offers character tables to enlarge the character set of passwords.
- Cross-platform support – runs under Linux, macOS, and Windows.
