Makes password guessing significantly more expensive
Encrypti0n uses Argon2id to derive encryption keys before AES-256-GCM encrypts your data.
Password Security Guide
Argon2id Key Derivation Explained
Passwords are designed for people to remember, not for computers to use as encryption keys. Argon2id bridges that gap by converting your password into a strong encryption key while making brute-force attacks significantly more expensive.

Argon2id Key Derivation
Makes password guessing significantly more expensive - Uses memory-hard key derivation for stronger protection - Allows security settings to balance protection and performance
01
Encrypti0n uses Argon2id to derive encryption keys before AES-256-GCM encrypts your data.
02
Argon2id settings can be adjusted to balance stronger protection with your device's performance.
03
The parameters used during encryption are stored with the encrypted data so the same key can be recreated during decryption.

Choosing the right Argon2id settings
Argon2id lets you balance encryption speed with resistance against password guessing attacks.
Lower settings
Faster encryption on slower devices with lower computational cost.
Balanced settings
A practical choice for most everyday encryption tasks.
Higher settings
Greater resistance against brute-force attacks by increasing memory and computation requirements.
Best practice
Always choose a long, unique password before increasing technical security settings.
What to expect
Helpful information before you begin
- Encrypti0n uses Argon2id to derive encryption keys before AES-256-GCM encrypts your data.
- Argon2id settings can be adjusted to balance stronger protection with your device's performance.
- The parameters used during encryption are stored with the encrypted data so the same key can be recreated during decryption.
- Built-in Password Intelligence and weak password warnings help users choose stronger passwords before encrypting important information.
Good to know
Security and privacy notes
- Argon2id greatly increases the cost of brute-force attacks, but it cannot compensate for weak, predictable, or reused passwords.
- Higher security settings require more processing time and memory, especially on older or low-powered devices.

Why isn't a password used directly as an encryption key?
Human-created passwords are rarely random enough to serve as secure encryption keys. Argon2id transforms your password into a cryptographically strong key by combining it with a unique salt and performing computationally expensive operations. This dramatically increases the resources an attacker needs to test password guesses while allowing legitimate users to recreate the same key using the correct password.

FAQ
Questions people ask before using this
No. Argon2id is a key derivation function (KDF). It converts your password into a secure encryption key before AES-256-GCM encrypts your data.
A unique salt ensures that identical passwords generate different encryption keys. This prevents attackers from reusing precomputed lookup tables across multiple encrypted files or messages.
Yes. Encrypti0n allows you to choose different Argon2id difficulty settings so you can balance stronger protection with the performance of your device.
Argon2id is designed to be memory-hard, meaning attackers need both significant computing power and memory to test password guesses efficiently. This makes large-scale brute-force attacks more expensive than with many older algorithms.
No. A strong key derivation function improves security, but it cannot fully protect weak, short, or reused passwords. Choosing a unique password remains the most important defence.
The stored parameters allow Encrypti0n to recreate the exact same encryption key during decryption without requiring users to remember technical configuration settings.
Yes. The built-in Password Intelligence tool analyses password strength, identifies weaknesses, and estimates resistance against different attack scenarios before you encrypt sensitive information.
