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. Zip password recovery online decryption service takes place on our servers, so there is no need to install additional software. If you have important security requirements for your data, you should instead consider using WinZip's AES encryption, described above. You should not rely on Zip 2.0 encryption to provide strong security for your data. 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. Legacy (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. The Zip file format extension used by WinZip to store AES-encrypted files is not supported by versions of WinZip prior to 9.0 and is not yet supported by some other Zip file utilities. The security of your data depends not only on the strength of the encryption method but also on the strength of your password, including factors such as length and composition of the password, and the measures you take to ensure that your password is not disclosed to unauthorized third parties. 256-bit AES is stronger than 128-bit AES, but both of them can provide significantly greater security than the standard Zip 2.0 method described below.Īn advantage of 128-bit AES is that it is slightly faster than 256-bit AES, that is, it takes less time to encrypt or decrypt a file.
These numbers refer to the size of the encryption keys that are used to encrypt the data. WinZip supports AES encryption in two different strengths: 128-bit AES and 256-bit AES.
This encryption method, also known as Rijndael, has been adopted by NIST as a Federal Information Processing Standard. Government's National Institute of Standards (NIST). The ZIP file format permits a number of compression algorithms.ĪES encryption: AES is the Advanced Encryption Standard, which is the result of a three-year competition sponsored by the U.S. A ZIP file contains one or more files that have been compressed, to reduce file size, or stored as is.
The ZIP file format is a data compression and archive format. Press here for ZIP Password Recovery / Decryption Online
