Here, you'll discover the frequently asked questions about using the sites Main App .
Feel free to reach out to me if you require additional assistance or would like to include a new question in the list.
General Information
What is Encrypti0n.com and what does it do?
Encrypti0n.com is a privacy-focused web application that enables users to easily encrypt and decrypt text and files, with advanced customization options tailored to individual security needs.
Do I need to create an account to use this app?
No account or registration is required; the app functions entirely in your browser.
Is any data stored online when I use this app?
No, all data and actions are handled locally in your browser; nothing is uploaded or stored on external servers.
Can Encrypti0n.com be used without an internet connection?
Yes, the application works offline since all encryption and decryption processes are executed within your browser.
Getting Started
How do I encrypt or decrypt a text message?
Enter your text and password (or use the generated one), then click the pink arrow to encrypt; to decrypt, the arrow turns blue—enter the same password to reveal the original message.
How do I encrypt or decrypt a file?
Select a file, input a password, and click the arrow button to encrypt or decrypt it using the same password logic as with text.
What happens if I enter the wrong password while decrypting?
If the password is incorrect, the encrypt/decrypt button will show an error icon to indicate a failure.
Password Management
What is the Local Password Manager?
It’s a local-only password storage system that lets you save up to 10 passwords for easy retrieval during encryption or decryption.
How many password slots are available?
There are 10 available slots for storing passwords.
How do I rename a password slot?
Open the "Rename Slots" dialog, choose a slot, enter a new name, and click “Save Slot Name.”
Can I export or backup my stored passwords?
Currently, there is no option to export or backup locally stored passwords.
File Handling and Storage
What is the difference between encrypting text and files?
Both use the same cryptographic algorithms, but file encryption splits files into chunks (each with a unique nonce), and generates a new Argon2 salt per file for improved security.
Where are my encrypted files stored?
Encrypted files must be downloaded from the app interface and can then be stored anywhere you choose.
Application Settings
What does the "Encrypt Application" option do?
It encrypts all relevant locally stored data (like the local password manager) with a user-defined master password using AES-GCM and Argon2id instead of a device-bound key.
What does the "Clear All Data" option do?
This action deletes locally saved data, including saved passwords and configuration settings and resets them with default values.
Can I change my master password later?
Yes, you can change the master password at any time from the app settings.
Is my master password stored anywhere?
No, it is not stored. If forgotten, you won’t be able to decrypt your encrypted app data.
Encryption Standards and Customization
What encryption standard does the app use?
Encrypti0n.com uses AES-GCM (Galois/Counter Mode) with a 256-bit key for both confidentiality and integrity.
What does “AES-GCM | 256-bit” mean?
AES-GCM is a modern encryption algorithm that makes sure that data is both securely encrypted and tamper-evident using a 256-bit symmetric key.
How secure is AES-GCM compared to other encryption modes?
AES-GCM is a state-of-the-art encryption mode combining strong confidentiality with built-in integrity checking, widely used in modern security applications.
Does this app use a secure random number generator?
Yes, it uses the secure crypto.getRandomValues() API provided by JavaScript.
Is the encryption process performed entirely on the client side?
Yes, all cryptographic operations happen directly in your browser via the Web Crypto API—no data leaves your device.
Advanced Cryptography and Configuration
What is Argon2 and why is it used?
Argon2 is a password-based key derivation function that makes brute-force attacks more difficult by applying computational cost and random salting.
What are Argon2 rounds and salt, and how do they affect security?
Round difficulty slow down key derivation to resist brute-force attacks, and salts add randomness to prevent the use of precomputed keys.
What Argon2 settings does the site use?
The site uses the Argon2id version of the algorithm, 64MiB of algorithm memory for every action and a parallelism of 1 due to JavaScript limitations.
What does changing salt length or round count do?
Modifying these parameters adjusts the strength of the key derivation process; each encrypted file/text stores these values in its header to ensure correct decryption.
What are the default cryptographic settings used?
By default, the app uses AES-GCM 256-bit encryption, Argon2id with 20 rounds, a 16-byte salt, and a new 12-byte nonce for each encryption.
Can I customize the Argon2 settings and what do the levels mean?
Yes, you can choose between Low, Middle, and High presets for both round count (from 5 up to 40) and salt length (12 or 16 bytes), providing control over encryption strength and performance.
