OpaqueFiles is file encryption software that encrypts/decrypts files so they can be stored securely, utilizing compression (Zstd/gzip/LZMA2), Reed–Solomon Error Correction, encryption(ChaCha20/AES-GCM-SIV) and keys derived from the user’s password with Argon2id.
It’s designed for users who want to store or archive files in the cloud while protecting the content of their files from the eyes of a cloud provider, hackers or other attackers that might have access to the files in the cloud. OpaqueFiles sacrifices some privacy for convenience by storing the names of files, their size and their modification date unencrypted.
This is cross-platform software running under Linux, macOS, and Windows.
OpaqueFiles is free and open source software.
Key Features
- Supports two encryption algorithms to keep your data safe:
- ChaCha20 is more modern and faster than AES, but less well tested, and can therefore be seen as less secure.
- AES256 – AES-GCM-SIV can be enabled in the configuration file. AES256 is old and reliable, and the recommended option if you want the highest level of security.
- Supports multiple modern compression algorithms, including no compression. No compression should be used when compressing data that was already compressed efficiently like images, videos and audio.
- Reed–Solomon Error Correction (Error Correction Code, ECC) is used by OpaqueFiles to recover from bit rot.
- Argon2id is used to ensure even weak passwords generate somewhat strong keys. This helps to keep the data secure.
- Verification.
- Scrubbing.
- Unix pipelines.
- Stress testing.
