Developer Documentation & Technical Information

Cryptographic Libraries & APIs Used

Encrypti0n.com uses modern browser-native cryptographic libraries:

• window.crypto : Secure random number generation and cryptographic operations.
• window.crypto.subtle : Provides essential cryptographic primitives like AES-GCM encryption/decryption and key imports.
• antelle/argon2-browser : Provides the Argon2id key derivation implementation for browsers (GitHub).

Some APIs are part of the Web Crypto API specification , offering robust, secure cryptographic functions directly within supported browsers.

Other Libraries Used

• Bootstrap v5 : Custom Bootstrap 5 template for the pages design (Official Page).
• jQuery v3.6.0 : Used for all DOM manipulation (Official Page).
• SweetAlert2 : For the informational popups (Official Page).
• HighlightJS v11.9 : For code highlighting (Official Page).

Open Source Code Availability

Encrypti0n.com strongly believes in transparency, which is why the complete source code is openly available on GitHub:

Developers, researchers, and privacy enthusiasts are encouraged to inspect, review, and contribute to enhance the project's reliability and security.

Internal Error Handling Mechanism

Encrypti0n.com uses precise and secure error handling aligned with the tamper-proof nature of AES-GCM encryption:

• AES-GCM Decryption Errors: When decrypting data, the Web Crypto API returns explicit errors if the provided key, nonce, or ciphertext is incorrect, indicating potential tampering or incorrect passwords.
• Tamper-proof Encryption: AES-GCM inherently provides authentication, meaning any alteration to the encrypted data will result in failed decryption, immediately alerting the user.

This ensures reliable security by always returning an error (e.g., wrong passwords) or potential data corruption or attacks. Read more here, in the Official Web Crypto API "Decrypt Method" Docs .

Example-Code:

try {
    decryptedData = await window.crypto.subtle.decrypt(
        { name: "AES-GCM", iv: iv },
        derivedKey,
        encryptedData
    );
} catch (error) {
    displayError("Decryption failed: Incorrect password or data integrity compromised.");
}

Browser Compatibility Notes

Encrypti0n.com depends on the Web Crypto API , widely supported by modern browsers. The following browsers are confirmed to support necessary cryptographic APIs:

• Google Chrome: Supported since version 37 (August 2014)
• Mozilla Firefox: Supported since version 34 (December 2014)
• Microsoft Edge: Supported since initial release (EdgeHTML) and fully in Edge Chromium (January 2020)
• Apple Safari: Supported since version 11 (September 2017)
• Opera: Supported since version 24 (September 2014)

Older or legacy browsers (such as Internet Explorer or significantly outdated browser versions) might lack proper Web Crypto API implementation, causing compatibility issues. Users are advised to update their browsers for full functionality and security.
