How To Zip And Encrypt A File Using Winzip _TOP_
File encryption is encrypting data in a file, protecting it from, and making it unusable by unauthorized people. The encryption process scrambles the data within the file, which can only be unscrambled (decrypted) with the right password or encryption key.

One of the best ways to encrypt files while enjoying reduced file size is by encrypting a zip file. Encryption and compression give you the benefits of both bank-level encryption and an unbeatable way of storing files.
Select your level of encryption within WinZip and add a strong password to protect your zip file. When you've added a password to the zip file, the content within gets encrypted, requiring a password to decrypt the file and get access to its content.
Standard Zip 2.0 is legacy encryption that even WinZip themselves consider weak. It is generally safe enough for everyday use to protect files not regarded as top secret or even secret. But the encryption method is easy to penetrate with specialized password recovery tools and skills.
The best and easiest way to encrypt your file is with specialized file encryption software. And to get the best of two worlds, compression, and file encryption, the best option is to use powerful compression software with built-in encryption features.
We hope you found this article useful. And when you decide to encrypt a file, preferably in AES with WinZip, make sure to choose a safe password, scan your computer for malware, and keep your password safe. These procedures make sure that your encrypted files stay secure.
If you are creating a Zip file in a folder window using the context menu (right click), you will have the option to encrypt the files and select encryption strength if the Add dialog is displayed. If you choose to add files to an existing Zip file using Add to recently used Zip file there will be no Add dialog and therefore no opportunity to encrypt the files while they are being added. In such a case, you can encrypt files after they have been added.
In each case, WinZip will ask for a password and then encrypt all files currently in the Zip file. Depending on the method you use, you may or may not have the option to change the encryption strength.
If a file in the Zip file is already encrypted, it will first be decrypted and then re-encrypted using the password and encryption method you specified. WinZip will first try to decrypt the file using the current password; if the file cannot be decrypted with this password, WinZip will ask you for the correct password. If you are unable to supply the correct password, the file can be skipped, and it will remain unchanged in the Zip file. The password you entered in the Encrypt dialog box will remain active until either you delete or replace it, or you close the archive.
My screen snips below are from Windows XP and WinZip 11.1. However, the process should be the same for Vista and Winzip 10.x users as well. WinZip 9.0 was the first version of WinZip that began using AES 256 bit encryption, so 9.x users should also be able to take advantage of using WinZip as an encryption tool.
2. Select the files you want to zip/compress and encrypt, right-click to bring up the context menus. Now under the context menus, click WinZip, Add to Zip file
Personally, If your just trying to secure 1 or 2 files, there is no purpose to use Winzip to encrypt a file when you can just use the native Encryption from Word or Excel. If however you wish to protect MULTIPLE files or send Multiple files over the internet to someone, WinZIP is nice because you can secure them in 1 large batch and be done with it. Just zip them up with a good password, send them the zip and your done (After you give them a phone call to tell them the password of course).
Refer to your specific file compression software user guide for instructions on how to compress and encrypt files. Known products compatible with IRS include, but are not limited, to WinZip and SecureZip.
7. Send this encrypted WinZip file to email@example.com. The password (set in Step #5) must not be included in the same message and should either be included in a separate email or verbally provided to Marquette University.
Using WinZip free or paid, you can open WinZip archives emailed to you using your iDevice. After opening a WinZip archive using the app, you can click to select any of its files and open them in the supported apps on your device. For example, on my Mac I created a WinZip archive containing a password-protected Word doc, an Excel spreadsheet, a PowerPoint presentation and a PDF file. Then I emailed the archive to my iPhone. I had no problems opening and viewing any of the files on my iPhone, including the password-protected Word file.
DTG 171952Z APR 07: "Safeguarding Personally Identifiable Information" provides, as an interim solution, the use of WinZip to encrypt files in those cases where a data-at-rest solution has not been implemented.
This guide focuses on showing you how to password protect .zip files on Windows 10, using all the best tools you could possibly need. Ensure that your files are in the right hands by applying a password only you know and only you can share.
Using the Encrypting File System (EFS) encrypts the data of your folder or .zip file and generates a decryption key that acts as a password. Only people with the exact, correct key will be able to decrypt the contents.
To encrypt files in a zip file and password protect the file, there are two applications that GMPF support, WinZip and 7-Zip. Winzip is a commercial application and requires a license, however 7-Zip is a free use application, and can be downloaded at no cost from the 7-Zip website. Please note that you may have to check with your IT department before downloading or installing 7-Zip.
4. After encrypting a file it is advisable to check that the encryption works, and that the password is correct. To do this, right click on the file, go to '7-Zip' and click 'Extract to /'. 7-Zip will then ask for a password, and if successfully entered will place the contents of the zip file in a folder of the same name.

The zip file will be created and ready for email attachment. If you already have a zip file that you would like to open, it is recommended that you have an archive extraction software such as WinZip or WinRAR. If you are using Windows 10 however, you have an option to extract the files manually.
E-mail is an inherently insecurecommunication medium. It is very important that sensitive information not be sent in e-mails, either in the e-mail subject/body or as an unsecuredattachment. This article explains how to secure an e-mail attachment byencrypting it and adding a password using a tool called WinZip.
There are two levels of security on a password-protected zip file: the encryption security and the password. There are currently two standard levels of encryption for zip files, 128 and 256 bits, with 256-bit encryption far superior to the 128-bit version. Fortunately, the major zip utilities support this level of encryption.
What immediately comes to mind for me is that PGP Zip offers public key encryption and its advantages in exchanging encrypted files with others. I consider public key encryption potentially more secure, since it's decryption requires possession of both the required private key and it's passphrase; while conventional encryption requires only the passphrase for decryption.
The above is really a discussion of symmetric encryption (first part of above) and asymmetric encryption (the latter part). While AES may be considered the best symmetric algorithm for symmetric encryption, there are other good ones that can be used, so that info is not complete. The asymmetric discussion above is also not fully correct. With asymmetric encryption used in PGP, the data is actually symmetrically encrypted (PGP defaults to using AES). It is then the randomly generated AES symmetric key used for the data encryption that is encrypted to a public key of the recipient. The recipient uses his/her private key to decrypt the AES key, and the AES key is then used to decrypt the data. So, in either case, symmetric encryption is used (because it is so much faster than asymmetric encryption. And the public key encryption is used as a secure way of transmitting the symmetric (in this case, AES) key.
Another feature that sets WinRAR apart from the other alternatives to WinZip is the function that allows users to estimate the size of the files to be packed as a zipped archive in advance. This proves to be a very big advantage if, for example, you want to zip a number of large files and drag them onto a USB stick or a CD. With WinRAR, you can choose the encryption method and protect your archives with a password as required.
To ensure that the sent files arrive safely with the recipient, the files can be encrypted using AES (advanced encryption standard) with up to 256 bits. The archives can only be unpacked by entering a defined password. With the file archiver, you can also create simple self-extracting archives. The receiver can open these even if they have not installed a packing program on their computer.
In terms of compression rate and speed, 7-Zip is an efficient and fast WinZip alternative. The ZIP and GZIP archives created with 7-Zip can be up to 10 percent smaller than other WinZip alternatives, depending on the form of encryption. In terms of speed, 7-Zip also performs better than many other similar applications. Only when it comes to in-house file formats (such as RAR files in WinRAR), do competitors have a small lead in terms of speed.
