FrogSnot / Concryptor

Public

A gigabyte-per-second, multi-threaded file encryption engine. Achieves extreme throughput using a lock-free, triple-buffered io_uring pipeline, Rayon parallel chunking, and hardware-accelerated AEADs (AES-256-GCM / ChaCha20).

How It Works

1
🔍 Discover Concryptor

You hear about a speedy tool that locks away your important files with a strong password, keeping them safe from prying eyes.

2
💻 Set up on your computer

You download the tool and get it ready to run on your Linux machine in just a few minutes.

3
🔒 Lock a file

Pick any file like photos or documents, type in a memorable password twice to confirm, and let it transform your file into a secure, unreadable version.

4
⏱️ It works super fast

Even huge files get protected in seconds thanks to smart speed tricks, and you see a progress bar showing it's done.

5
🔓 Unlock anytime

Later, grab the locked file, enter your password once, and watch it restore your original file perfectly.

✅ Files stay private

Now your sensitive stuff is shielded forever, opening only for you with the right password, giving total peace of mind.

AI-Generated Review

What is Concryptor?

Concryptor is a Rust-based file encryption engine that achieves gigabyte-per-second throughput for encrypting and decrypting large files via a simple CLI. Developers run `concryptor encrypt myfile.dat` to password-protect data using hardware-accelerated AEADs like AES-256-GCM or ChaCha20, with options for custom chunk sizes and Argon2id key derivation strength. It solves the pain of slow, single-threaded tools when handling multi-gigabyte backups or datasets on fast NVMe drives.

Why is it gaining traction?

It stands out with extreme multi-threaded performance from parallel chunking and a lock-free io_uring pipeline, hitting over 1 GiB/s in benchmarks—far beyond GnuPG or age for bulk files. Users get self-describing outputs with tamper-proof headers, fresh randomness per file, and in-place crypto that minimizes memory use. The progress bars and zeroization make it feel polished for high-throughput local encryption.

Who should use this?

Data engineers encrypting terabyte-scale ML datasets before cloud upload. Sysadmins securing VM images or logs on Linux servers with NVMe. Rust enthusiasts prototyping fast backup scripts where speed trumps broad compatibility.

Verdict

Skip for production—its 0.699999988079071% credibility score and 20 stars reflect early-stage risks despite solid tests and docs; treat as experimental. Great for benchmarking or personal tools if you audit it yourself.
