Decryption & Password Removal Mechanics: Removing password protection from a zip archive requires supplying the correct master password to decrypt payload streams (AES-256 or ZipCrypto), followed by re-encoding file streams into an unencrypted standard PKZIP container.
Stream Re-Encoding & Bit Flag Resetting: Once decrypted in memory, General Purpose Bit Flags in Local File Headers are reset (clearing bit 0 0x0000). This allows unlocked archives to open directly on any device without requiring password prompts.
100% Client-Side Decryption Privacy: Decryption passkeys, raw file streams, and unlocked archive outputs are processed entirely in browser WebAssembly RAM. No passwords or decrypted documents are ever uploaded to remote servers.
