Encrypting a Zip File - WinZip

WinZip applications support 128- and 256-bit key AES encryption, which provides much greater cryptographic security than the traditional Zip 2.0 encryption method used in earlier versions of WinZip.WinZip 12.0 introduced customizable password policies to configure password complexity requirements when using encryption in WinZip. Setting a minimum password length and a required mixture of letters, numbers, and/or characters are user defined options (see Password Policy). The options that can be specified are upper case letters, lower case letters, numerals, and symbols.With WinZip Enterprise, System Administrators can customize the MSI installation of WinZip to set and lock down password policy requirements that meet their organization's needs for password complexity. Additionally, WinZip Enterprise can be deployed to take advantage of the Windows FIPS 140-2 validated cryptographic modules.WinZip's advanced encryption (FIPS-197 certified) uses the Rijndael cryptographic algorithm which, in 2001, was specified by the National Institute of Standards and Technology (NIST) in Federal Information Processing Standards (FIPS) Publication 197 as the Advanced Encryption Standard (AES).When properly implemented as a key component of an overall security protocol, AES permits a very high degree of cryptographic security, yet is fast and efficient in operation.WinZip's AES encryption is just as easy to use as traditional Zip 2.0 encryption: all you have to do is select the encryption method and specify your password.In addition to AES encryption technology, WinZip provides a number of usability enhancements that make it easier for you to use encryption. Most noticeably, you can easily encrypt the contents of an existing Zip file. If you are using version 14 or later, WinZip will recognize Intel-based computers with built-in AES encryption and use the available hardware support to make encryption operations two to three times faster.Those to whom you send AES-encrypted Zip files will need a compatible Zip file utility to decrypt the files. The full specification for creating WinZip-compatible AES-encrypted Zip files is published in order to enable other Zip file utility vendors to provide support for the format.

Composition of the password and the measures you take to ensure that your password is not disclosed to unauthorized third parties. Please read about encryption passwords and about password policy standards defined in the WinZip configuration.Note that the Zip file format extension used by WinZip to store AES-encrypted files is supported by WinZip 9.0 or later and is supported by some other Zip file utilities. Because the technical specification for WinZip's AES format extension is available on the WinZip web site, we anticipate that other Zip file utilities will add support for this format extension.Standard Zip 2.0 encryption: this older encryption technique provides a measure of protection against casual users who do not have the password and are trying to determine the contents of the files. However, the Zip 2.0 encryption format is known to be relatively weak, and cannot be expected to provide protection from individuals with access to specialized password recovery tools.You should not rely on Zip 2.0 encryption to provide strong security for your data. If you have important security requirements for your data, you should instead consider using WinZip's AES encryption, described above.The only advantage of Zip 2.0 encryption over the more secure AES encryption is that it is supported by most Zip file utilities, including earlier versions of WinZip. Files that you encrypt using this technique can be extracted by anyone who knows the correct password and has access to almost any Zip file utility. Additionally, Zip 2.0 encryption is supported by WinZip Self-Extractor 2.2

Salt values.As part of the process outlined in RFC 2898 a pseudorandom function must be called; WinZip uses the HMAC-SHA-1 function for this purpose, since it is a well-respected algorithm that has been in wide use for this purpose for several years. The PBKDF2 function repeatedly calls HMAC-SHA-1, which produces a 160-bit hash value as a result, mixing the outputs in a fairly complicated way, eventually yielding a 128- or 256-bit encryption key as a result.Note that, if you are using 256-bit AES encryption, the fact that HMAC-SHA-1 produces a 160-bit result means that regardless of the password that you specify, the search space for the encryption key is unlikely to reach the theoretical 256-bit maximum, and cannot be guaranteed to exceed 160 bits. This is discussed in section B.1.1 of the RFC 2898 document.Information for software developersZip file utility developers who wish to provide WinZip-compatible AES encryption support in their own products can find complete technical information on the WinZip web site.Using EncryptionEncryption PasswordsPassword Policy in your WinZip configurationWipe Feature.

Or later and by WinZip Self-Extractor Personal Edition (included with WinZip); the AES encryption method described above is only supported by WinZip Self-Extractor 3.0 or later.Limitations to be aware ofWinZip's AES encryption facility represents a significant advance on the previous Zip 2.0 encryption, and it can help meet the need that many WinZip users have for preventing their confidential information from being viewed by unauthorized individuals. There are, however, some limitations that you should be aware of:Encryption applies only to the contents of files stored within a Zip file. Information about an encrypted file, such as its name, date, size, attributes, CRC, and compression ratio, is stored in unencrypted form in the Zip file's directory and can be viewed, without a password, by anyone who has access to the Zip file.WinZip's encryption method is not the same thing as an authentication method for the Zip file. WinZip encryption is intended to prevent someone who doesn't know the correct password from finding out the contents of your encrypted data. The password is not needed for actions that do not involve decryption of the encrypted contents of data stored within a Zip file. In particular, encrypted files can be deleted from a Zip file, or can be renamed within a Zip file, and new, unencrypted, files can be added to a Zip file, without a password.WinZip uses password-based encryption, and even a strong encryption algorithm like AES is of little or no benefit if the passwords you use are weak, or you
