About this app

In a digital world, nothing is more important than your privacy. Whether you're sending a password, saving a private note, or protecting sensitive info, you need a powerful tool you can trust.



Welcome to Crypto Text, the simple, modern, and secure way to encrypt and decrypt text right on your device.



Built on a Foundation of Real Security

Our app is built for your privacy. All encryption and decryption happens locally on your device—your password and your data never leave your phone, ensuring complete confidentiality.



Key Security Features:

Strong Encryption Standard: We use AES-256, the standard trusted by governments and security experts worldwide. Learn more about AES.

Robust Key Derivation: We derive a secure key using the modern industry standard, PBKDF2 with HMAC-SHA256, to protect against brute-force attacks.

Proper Cryptographic Implementation: Every encrypted message uses a unique, cryptographically secure salt and initialization vector (IV), protecting your data from pattern analysis attacks.



Perfect For:

Protecting Secrets: Keep passwords, API keys, recovery phrases, or private notes safe from prying eyes.

Sending Secure Messages: Encrypt a message before sending it through email, chat, or social media. Only the person with the correct password can read it.

A Universal Decryption Tool: Our app is designed for compatibility, making it a great utility for decrypting text from other standard AES tools.

Digital Diary: Keep your private thoughts and journal entries completely secure.



Features

✓ Strong Security: Uses AES-256 and PBKDF2-SHA256 to keep your data safe.

✓ Works Offline (Premium): Core encryption/decryption works offline for premium users.

✓ One-Tap Copy: Easily copy results to your clipboard.

✓ Dark Theme: A clean, easy-on-the-eyes interface.

✓ Privacy Focused: We request no unnecessary permissions. Your privacy comes first.



How It Works

Simple, 4-Step Process:

1. Type or paste the text you want to protect.

2. Enter a strong, memorable password or PIN.

3. Tap "Encrypt" to get a secure, shareable block of text.

4. To decrypt, paste the text and enter the exact same password.



Important Information

Your Password is Your Key: Your data's security depends on your password's strength. We recommend choosing a password that is difficult to guess.

We Cannot Recover Your Password: For your security, we never store or see your password. If you forget it, your data cannot be recovered. Please be careful and store your password safely.

Compatibility: This app can only decrypt compatible AES text with the correct password.

Character Limit: A character limit is in place to ensure smooth performance on all devices.

Ratings and reviews

By far the worst app the has to add that won't let you go back to the original platform of the app but instead continuously pushes you to the add product. I can understand the revenue but when you can't use the app it's pointless. place the ad at the bottom as a non pop-up and go from there when you have a stalker ad that gets you stuck and can't use the app your not going to get the download your needing. it's there a pro version

The app is not revealing any information on the protocol besides that it is AES. Which block mode? Which key size? Which key derivation function? The UI is not very intuitive... Avoid.

Awesome Navigation and overall UI. Great app. Keep it up..!!
