Kali Linux Zip -

zip -e -o archive.zip files/ -P "pass" Then verify encryption type:

zip2john protected.zip > zip_hash.txt This tool extracts the hashed password from the archive. For modern AES-256 encrypted ZIP files, zip2john will still work, but the resulting hash format is different (often starting with $zip2$ ). With the hash file ready, use John in dictionary mode: kali linux zip

echo "[*] Extracting hash..." zip2john "$ZIPFILE" > "$HASHFILE" zip -e -o archive

#!/bin/bash if [ $# -ne 1 ]; then echo "Usage: $0 <encrypted.zip>" exit 1 fi ZIPFILE=$1 HASHFILE="$ZIPFILE.hash" 7z a -p"secret" -mhe=on -tzip archive

zipdetails archive.zip | grep "Compression method" Output should show AES-256 .

7z a -p"secret" -mhe=on -tzip archive.zip folder/ The -mhe=on flag hides the file list (header encryption), something the standard zip command cannot do. When dealing with untrusted ZIP files (e.g., malware samples), you must extract safely without executing any embedded scripts or auto-run features.

zip --password "MyStr0ngP@ss" -e -r archive.zip sensitive_folder/ To enforce AES-256 (not legacy ZipCrypto), use:
