Securing Your Workspace: A Deep Dive into DomoDomo Local File Encryption
Security and privacy are the core pillars of DomoDomo. In this article, we take a deep dive under the hood to see how the File Encryption Tool uses modern browser features to protect your sensitive files offline.

🔑 The Web Crypto API: Safe Browser Encryption
DomoDomo does not use external encryption services. Instead, it relies on the Web Crypto API, a low-level cryptographic interface built directly into modern web browsers by W3C standards.
This ensures:
- Fast Execution: Browser-native C++ implementations execute cryptographic operations rapidly.
- Hardware Security: Uses secure random number generators built into your computer's CPU.
- Offline Reliability: Works 100% offline with zero network latency.

🛡️ AES-GCM 256: Industry Standard Security
When you encrypt a file in DomoDomo:
1. Key Derivation (PBKDF2): The tool takes your custom password and feeds it into the Password-Based Key Derivation Function 2 (PBKDF2) along with a random salt value to generate a strong 256-bit key.
2. Encryption (AES-GCM): The file is encrypted using Advanced Encryption Standard (AES) in Galois/Counter Mode (GCM) with 256-bit keys. GCM mode ensures both confidentiality (hiding the file content) and authenticity (detecting if anyone tries to tamper with the file).
3. Decryption: The encrypted file, salt, and initial vectors are outputted as a secure package, ready to be safely decrypted on any browser using the same password.
