Personally Identifiable Information ( PII). An encrypted Zip file, however, is useless to malicious actors because they cannot decrypt the contents.Įncrypted Zip files are especially useful when your files contain sensitive information, such as: Once the recipient downloads the encrypted Zip file, they can decompress the contents back to their original state without degrading the data quality.ĭuring the time it takes to email a file or upload it to the cloud, cybercriminals could potentially intercept and steal the data. Compressed Zip files transmit in one-tenth of the time of their uncompressed counterparts. Reducing the file size also increases transfer and download speeds. Zip files reduce file size through lossless compression, which removes data redundancies without impacting the overall file quality. When you encrypt a Zip file, its contents are locked down and accessible only to specific, authorized users. Zip files can store hundreds of files and folders in a single location. Why You Need to Encrypt Zip Files for Your Business In this article, we will look at the benefits and uses of encryption for Zip files and detail the steps for encrypting your Zip files with WinZip® Enterprise. In addition to saving disk space, some compression tools also encrypt data at the file level, enhancing your data protection strategies. Zip is an archive file format that can compress one or more files and/or folders into a single, smaller file. 
Without the correct key, the encrypted data cannot be transformed back into readable plaintext.Įncryption is an important security measure for all your digital content, including Zip files. Using complex algorithms, encryption scrambles information into an undecipherable format known as cyphertext. When storing or transmitting data files over networks, encryption prevents unauthorized access by malicious actors. Encryption adds an additional layer of protection for sensitive or confidential information.
