Cryptext: Text Encryptor

Eypeh Labs

About this app

Cryptext is a simple, powerful app to encrypt text and decrypt it with a password — completely offline. Turn any private message, note, or password into secure, unreadable encrypted text, share it anywhere, and let only the right person decrypt it.

Whether you need to send a private message, protect sensitive notes, or share a password securely, Cryptext encrypts your text locally on your device. No internet. No accounts. No tracking.

WHY CRYPTEXT

- Encrypt text and messages with a password in seconds
- Decrypt encrypted text anywhere, on any device with the app
- Share encrypted messages through any app — chat, email, notes, anywhere
- 100% offline — your text and password never leave your device
- Real, strong encryption — not a gimmick

REAL ENCRYPTION, DONE RIGHT

Cryptext uses AES-256 encryption with a scrypt-derived key — the same proven standards used to protect banking and private messaging. A fresh random salt and value are generated for every message, so the same text never produces the same encrypted output twice. Every message is authenticated, so tampering is detected instead of silently changing your text.

PRIVATE BY DESIGN

- No internet permission — the app physically cannot send your data anywhere
- No account, no sign-up, no analytics, no tracking
- Nothing is stored on a server — there is no backdoor and no recovery
- Decrypted text copied to your clipboard clears automatically

HOW IT WORKS

1. Type or paste your text and choose a password
2. Tap Encrypt and share the secure result anywhere
3. The recipient pastes it into Cryptext and enters the password to decrypt

Always share the password separately from the encrypted message, through a different channel.

PERFECT FOR

- Sending private, password-protected messages
- Encrypting sensitive notes, passwords, and personal information
- Securely sharing text over chat, email, or social apps
- Anyone who wants private, offline, password-protected encryption

Cryptext is a private text encryption and decryption tool. It is not a messenger and does not replace end-to-end encrypted apps for live chats. Its security depends on the strength of the password you choose.

Encrypt text. Share securely. Decrypt with a password. 100% private, 100% offline.
