So till here we discuss about compression classes and cryptography classes now we will discuss about the password mechanism in our tool to achieve our password protected zip. Solution In a nutshell we are injecting a text file inside our zip.
This text file will contain our key which is supplied as password for generating the zip file. For obvious security reasons this supplied password is encrypted before being appended in the text file. After this we encrypt each file using the same password and add it into the zip file.
The generated file will have all files encrypted which makes this zip safe from unauthorized access. Steps to create password Create a file name Zip.
Src Encrypt the password string. Append the encrypted string into Zip. So once we have user password encrypted and appended in zip. After this file is inserted the foreach loop will starts iterating other files and folders in the source folder and add them one by one.
You must be thinking what happens to that Zip. One important point here to note is we are processing our files one by one why not all together? The reason is we are encrypting our each file before adding into zip.
This way our zip is encrypted and it is of no use until the correct password of the zip is supplied. The purpose of whole article is to encrypt the zip using. A user has an option of overwriting the existing file.
If user do not select overwrite option and if file or folder is found the zip operation would not execute. We encrypt the supplied password and try to match the contents of zip. If content matches, it confirms that the supplied password is the real password for this zip and we start processing our unzipping operation.
The code iterates the zip and extract file one at a time, the extracted files are decrypted earlier so again the supplied password is used as key for decryption.
Explain the topic of the article with code and description Block of code should be set style as "Code" like below.If we end up merging our files into the existing archive, we can then check if we want every file to go in or not.
We can overwrite every matching file, we can overwrite the matching files only if the files to be put in are newer, or we can ignore the file to be put in if there is already a match.

Jul 24, · Is it possible to using Powershell, Unzipping, force 'yes' to all, rename, don't overwrite existing files. Expand a zip file to a folder: Syntax Expand-ZipFile [-FilePath] Object [[-OutputPath] Object] [-Force] [CommonParameters] Key -FilePath The path of the zip file that needs to be extracted.
-OutputPath The path where we want the output folder to end up.
