Frequently Asked Questions

Alpha Encryptor is a free, client-side encryption service that allows you to encrypt and decrypt text using military-grade AES-GCM encryption (a variant of AES). All operations happen in your browser, ensuring your data never leaves your device.

Yes! Alpha Encryptor is completely free to use with no hidden costs, subscriptions, or premium features. We believe everyone should have access to secure encryption tools.

No account is needed. You can start encrypting and decrypting immediately without any registration or login.

We use AES-GCM (Advanced Encryption Standard - Galois/Counter Mode), a variant of AES encryption that's the same standard used by governments and security professionals worldwide. It's considered military-grade and virtually unbreakable with a strong passphrase.

Your data is NOT stored anywhere. All encryption and decryption happens entirely in your browser using JavaScript. Your text and passphrase never leave your device and are never sent to our servers.

No. This is by design for maximum security. We never see or store your passphrase, so there's no way to recover it. If you lose your passphrase, your encrypted data is permanently inaccessible.

Only someone with the exact passphrase you used can decrypt your data. Without the passphrase, the encrypted text is mathematically impossible to decrypt in any reasonable timeframe.

A passphrase is your secret key for encryption and decryption. Think of it as a password, but it can be longer and include spaces. It's what protects your encrypted data.

1) Click the 'Encrypt' tab, 2) Enter the text you want to encrypt, 3) Enter a strong passphrase, 4) Click the 'Encrypt' button, 5) Copy the encrypted output and save it somewhere safe.

1) Click the 'Decrypt' tab, 2) Paste your encrypted text, 3) Enter the SAME passphrase you used to encrypt it, 4) Click the 'Decrypt' button, 5) Your original text will appear.

A strong passphrase should be: at least 12 characters long, include a mix of uppercase and lowercase letters, numbers, and symbols, not be a common word or phrase, and be something you can remember. Example: 'MyDog!Loves2Swim@Beach'

Yes, you can reuse the same passphrase for multiple encryptions. However, for maximum security, consider using different passphrases for different types of sensitive data.

Click the keyboard icon next to the passphrase field to open the virtual keyboard. You can type letters, numbers, and click 'Password Symbols' to access special characters. Use 'Shift' for uppercase letters.

We use AES-GCM (Advanced Encryption Standard - Galois/Counter Mode), specifically AES-256-GCM. This is a variant of AES encryption implemented using the Web Crypto API.

AES (Advanced Encryption Standard) is a symmetric encryption algorithm adopted by the U.S. government and used worldwide. AES-GCM is a variant that adds Galois/Counter Mode for authenticated encryption, providing both confidentiality and integrity. It's considered one of the most secure encryption methods available.

Once the page is loaded, the encryption and decryption functions work entirely in your browser and don't require an internet connection. However, you need internet to initially load the page.

Alpha Encryptor works on all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. We recommend using the latest version of your browser for the best experience.

The application is built with Next.js and TypeScript using open-source encryption libraries. The encryption process is transparent and uses well-established cryptographic standards.

The most common reasons are: 1) You're using a different passphrase than the one used for encryption (even one character difference will fail), 2) The encrypted text was copied incorrectly (make sure you copied the entire encrypted string), 3) The text wasn't encrypted with this service.

Unfortunately, there's no way to recover a forgotten passphrase. This is a security feature, not a bug. Always store your passphrases securely, such as in a password manager.

Yes! Encrypted text should look like random characters and symbols. This is normal and expected. It's the result of the encryption algorithm transforming your text into an unreadable format.

Yes! As long as you have: 1) The encrypted text, 2) The exact passphrase used for encryption, and 3) Access to Alpha Encryptor (on any device), you can decrypt your data anywhere.

Make sure your browser allows local storage. The theme preference is saved in your browser's local storage. If you're in private/incognito mode, the theme may reset when you close the browser.

Currently, Alpha Encryptor only supports text encryption. You cannot directly encrypt files, images, or other binary data. Consider using specialized file encryption tools for those purposes.
