Password-Protected ZIP archives in Bharat utilize AES-256 bit encryption to wrap digital assets in a cryptographically secure container. Since this OTechy tool is a client-side utility, it performs the DEFLATE compression algorithm locally in 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.
