Decryption Settings
Password-Protected ZIP archives in Bharat utilize AES-256 bit encryption to unwrap digital assets from their secure containers. Since this OTechy tool is a client-side utility, it performs the INFLATE decompression algorithm locally within the browser's sandbox. This ensures that sensitive documents, KYC files, and corporate data are never transmitted over the network or cached on any external server, providing 100% data residency and absolute privacy for Indian users.
Privacy Assurance: This tool performs Local Verification. Whether you choose individual files or a ZIP bundle, the decryption happens entirely within your browser's memory. No passwords or file data ever cross the network.

Frequently Asked Questions

What is the "Unprotected ZIP" option?

This allows you to convert a password-locked ZIP into a regular ZIP. The tool decrypts the files locally and re-packages them so you can open them later without a password.

Is it safe to enter my password?

Yes. OTechy tools are Serverless. Your password is used by your browser's own decryption engine and is wiped the moment you close the tab.

Why did my extraction fail?

Failure usually occurs due to an incorrect password (Signature Mismatch) or if the ZIP was created using a non-standard proprietary compression method.

Does it support AES-256?

Absolutely. It supports military-grade AES-256 encryption, which is the standard for secure documents and KYC files in Bharat.

Are there file size limits?

While we don't set a limit, extraction happens in your RAM. For archives over 500MB, ensure your device has enough available memory for a smooth process.
