Password-Based Encryption Explained
Password-based encryption is simple to use and highly secure when combined with strong passwords and modern cryptography. Encrypti0n uses Argon2id to derive secure encryption keys from your password before protecting your data with AES-256-GCM.

Try it out
The four foundations of secure password-based encryption
Strong encryption depends on both modern cryptography and good password habits.
Generate
Create a long, random, and unique password using a secure password generator.
Strengthen
Argon2id converts your password into a secure encryption key before AES-256-GCM protects your data.
Protect
Never reuse passwords across different files, projects, or services.
Review
Use Password Intelligence to evaluate password strength before encrypting important information.
What to expect
Helpful information before you begin
- Encrypti0n derives encryption keys locally using Argon2id before encrypting data with AES-256-GCM.
- Argon2id security settings can be adjusted to balance stronger protection with device performance.
- Weak password warnings and Password Intelligence help users identify passwords that may be vulnerable to guessing attacks.
- Optional application encryption uses a master password to protect locally stored settings and saved passwords.
Good to know
Security and privacy notes
- Modern encryption cannot compensate for weak, predictable, or reused passwords.
- Reusing the same password across multiple encrypted files or services increases the impact if that password is ever compromised.
Best next step:
Encrypt with a Password and keep passwords unique, long, and stored safely.
Real-world use cases
Where Password-Based Encryption fits into everyday workflows
Security works best when it supports the task people are already trying to complete.
Protecting personal backups
Encrypt backup files before storing them on external drives, NAS systems, or cloud storage.
Encrypting confidential files before sharing
Protect files with a strong password before sending them to clients or collaborators.
Securing passwords, recovery codes, and sensitive notes
Use password-based text encryption for high-value snippets that should not remain readable.
Protecting locally stored application data
Use the master-password workflow to protect saved slots, settings, and local configuration.

Strong encryption starts with a strong password
Password-based encryption allows you to protect information without managing certificates or complicated key files. The quality of your password, however, directly affects the security of your encrypted data. A long, unique password combined with Argon2id key derivation dramatically increases the difficulty of brute-force attacks while remaining easy to use in everyday workflows.

FAQ
Questions people ask before using this
Long, unique passwords are significantly more resistant to guessing attacks than short or commonly used passwords. Randomly generated passwords are recommended whenever possible.
No. Every important file, project, or encryption workflow should have its own unique password. Reusing passwords increases the damage if one password is ever exposed.
Yes. Even though AES-256-GCM and Argon2id provide excellent protection, an attacker can still target weak or predictable passwords through brute-force or dictionary attacks.
Generally no. Organisations should use separate passwords for different projects or teams, rotate them regularly, and limit access to only the people who need it.
Yes. Encrypti0n includes Password Intelligence, which analyses password strength, highlights weaknesses, and estimates resistance against different attack scenarios.
The master password secures Encrypti0n's locally stored application data, including password slots and configuration settings. It is separate from the passwords you choose for encrypting individual files or messages.
Argon2id makes password guessing much more expensive by requiring significant memory and computation for every password attempt. This helps protect encrypted data against modern brute-force attacks.
