# Unzip a password protected zip file on Ubuntu
###### tags: `Ubuntu` `zip`
```
$ unzip -P <password> <file.zip>
```
If you are getting an `unsupported compression method 99` error.
That means your ZIP file is ==AES encrypted== which is not supported by `unzip`

You can use `7zip` to instead.
```
$ sudo apt install p7zip-full
$ 7za x -p<PASSWORD> file.zip
```
