Why Kalyvor
Built for people who value their time
Every security tool is fast, private and genuinely free — no dark patterns, no surprises.
Fast cloud processing
Jobs run on dedicated workers and finish in seconds — no queue, no spinner you can go make coffee to.
Auto file deletion
Everything you upload is erased the moment the job finishes. Nothing is written to long-term storage, so there is no retention period to wait out.
Works everywhere
Desktop, tablet or phone, any modern browser. Nothing to install, no plugins, no extensions.
Batch processing
Drop in a folder's worth of files and run the whole set through one tool in a single pass.
Privacy first
Encrypted in transit, never used to train models, never sold. Many tools never send the file at all.
No installation
Open a tab and go. No account needed to start, no download, no licence key to hunt for.
How it works
Text Encryption in three steps
No account, no installation, no manual. It takes about as long to do as it does to read.
- 01
Choose Encrypt or Decrypt
One mode at a time — the passphrase field and result both follow it.
- 02
Enter or generate a passphrase
Stretched into an AES-256 key via PBKDF2 — a random salt every time, never used as the key directly.
- 03
Paste your text and run it
The exact text to encrypt, or the encrypted output to decrypt — updated the moment you press the button.
