SYNOPSIS

zipcloak [-d] [-O output] [options] zipfile

zipcloak encrypts or decrypts ZIP archives by adding or removing password protection. When encrypting, it prompts for a password and applies encryption to all files within the archive. When decrypting with the -d flag, it removes encryption after verifying the original password.
By default, zipcloak modifies the archive in place, replacing the original file. The -O option allows writing the encrypted or decrypted result to a new file, preserving the original archive unchanged.
zipcloak uses standard ZIP encryption (PKZIP), which is widely compatible with most ZIP tools and operating systems. It is part of the Info-ZIP suite of utilities.
