OpaqueFiles is a file encryption application designed to protect documents and other data before they are stored locally or uploaded to cloud services. It combines encryption, compression and error correction to provide a convenient way of creating protected archives.
The application supports ChaCha20 and AES-GCM-SIV encryption, with encryption keys derived from user passwords using Argon2id. It also offers several compression methods and Reed–Solomon error correction to improve resilience against storage corruption. OpaqueFiles prioritises convenience over complete metadata confidentiality: filenames, file sizes and modification dates are not encrypted, so users should consider whether this information is sensitive before choosing the application.
This is free and open source software.
Key Features
- Supports ChaCha20 and AES-GCM-SIV encryption algorithms.
- Uses Argon2id for password-based key derivation.
- Offers Zstandard, gzip and LZMA2 compression, with the option to disable compression.
- Provides Reed–Solomon error correction to help recover data affected by storage corruption.
- Includes verification and scrubbing operations for checking stored data.
- Supports Unix pipelines for integration into command-line workflows.
- Provides stress-testing functionality for assessing data integrity.
- Cross-platform support – runs under Linux, macOS and Windows.
