If you are uploading encrypted Zip files to Amazon or Azure, it's possible that file names and paths are being extracted and indexed, perhaps by Cortana in OneDrive, even though you intend to keep the contents of the Zip files 100% private.
#Zip or tar better for mac archive#
Imagine capturing an archive that contained files like "DivorceAttorneys.xls" or "\Contracts\2016\Panama-Gov\OffShoreAccounts.pdf". Beyond the compatibility problem, file names and folder paths are "metadata" which can be very revealing all by themselves, even if the file contents are encrypted.
However, there is a compatibility problem: Zip with AES is not supported by many operating systems or other archival tools for example, Windows File Explorer does not support AES-encrypted Zip files and probably never will.Ī third problem with AES-encrypted Zip files is that some vendors will encrypt the names and paths of files inside the Zip archive, while others do not. Zip archives can also be encrypted with 256-bit AES, which is much more secure.
When compatibility across operating systems and archival tools is more important than security, then use the Zip format (not 7z) either with no encryption or with ZipCrypto/PKZIP encryption (not AES). ZipCrypto/PKZIP encryption should never be used when security is the primary concern. The original ZipCrypto/PKZIP method is the most widely compatible, but is fatally flawed ( overview and academic paper on the problems). Zip archives can be encrypted with the original "ZipCrypto" stream cipher (also known as the PKZIP cipher) or with AES. Both the Zip and 7z archive formats can be encrypted with a user-supplied passphrase. Most importantly, 7-Zip supports archive encryption. Unlike the old Zip archives, modern 7-Zip archives (in 7z format) can be up to 16,000,000 TB in size! Archive Encryption (Zip Format) It supports a wide variety of formats (like 7z, zip, tar, wim, iso, rar, and rpm) and can be run from the command line or as a graphical application. Is there a better alternative? 7-Zip Is Better (and Free)ħ-Zip is a free, open source, cross-platform, very fast, archive file manager. However, these cmdlets do not support encryption, are relatively slow, cannot handle other archive formats, cannot peek at file listings inside of Zip archives without doing extraction, and cannot handle files larger than 2 GB (which is a big problem for archiving log files).įor this article, it's the lack of encryption support which is the real deal-killer.
