The RAR5 file format removed comments for each file (though archive comment still remains), authenticity verification, and specialized compression algorithms for text and multimedia files. Options added in v5.0 include 256-bit BLAKE2 file-hashing algorithm instead of default 32-bit CRC32, duplicate file detection, NTFS hard and symbolic links, and Quick Open record to allow large archives to be opened faster. Maximum path length for files in RAR and ZIP archives is increased to 2,048 characters. AES encryption, when used, is in CBC mode and was increased in strength from 128- to 256-bit. The RAR5 file format increased the maximum dictionary size to 1 GB 11 different compression directory sizes from 1 MB to 1 GB are available, with the default in version 5 increased from 4 MB to 32 MB, typically improving compression ratio. WinRAR versions before 5.0 do not support RAR5 archives only older versions of WinRAR run on Windows versions prior to Windows Vista, and cannot open RAR5 archives. Support for the archive format RAR5, using the same RAR file extension as earlier versions, was added in version 5.0 the older RAR file format has since been referred to as RAR4. WinRAR and the RAR file format have evolved over time. Related programs include the command-line utilities "RAR" and "UNRAR" and versions for macOS, Linux, FreeBSD, Windows CE, and MS-DOS. An Android application called "RAR for Android" is also available. WinRAR supports creating encrypted, multi-part and self-extracting archives. To enable the user to test the integrity of archives, WinRAR embeds CRC32 or BLAKE2 checksums for each file in each archive. It can create and view archives in RAR or ZIP file formats, and unpack numerous archive file formats. WinRAR is a trialware file archiver utility for Windows, developed by Eugene Roshal of win.rar GmbH. Trialware ( nagware for individual users) It can be helpful when unpacking a non-solid archive containing files encrypted with different passwords.Arabic, Armenian, Azerbaijani, Basque, Belarusian, Bulgarian, Burmese, Catalan, Chinese Simplified, Chinese Traditional, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, Galician, Georgian, German, Greek, Hebrew, Hungarian, Indonesian, Italian, Japanese, Korean, Lithuanian, Mongolian, Norwegian, Persian, Polish, Portuguese, Brazilian Portuguese, Romanian, Russian, Serbian Cyrillic, Slovak, Slovenian, Spanish, Colombian Spanish, Swedish, Thai, Turkish, Ukrainian, Uzbek, Vietnamese Name of unpacking file is now included into WinRAR incorrect password warning for RAR5 archives. When using "File/Change drive" command, WinRAR saves the last folder of previous drive and restores it if that drive is selected again later.ħ. Previous versions ignored -ri and set the priority to low in the presence of -ibck switch.Ħ. If -ibck -ri switches are used together, WinRAR process sets the priority specified in -ri switch. It can be useful if only the archive type or total information is needed.ĥ. Switch -idn hides archived names also in 'v' and 'l' commands. In the past this extended error information was available in WinRAR, but not in SFX archives.Ĥ. Now this message is followed by a detailed reason like access denied or file being used by another process. Where appropriate, SFX archive displays the additional line with detailed error information provided by operating system.įor example, previously such archive would display "Cannot create file" message alone. We would like to express our gratitude to Igor Sak-Sakovskiy for bringing this issue to our attention.ģ. In limiting the practical application of this attack. Such attack is only possible if the intruder has managed to spoof or otherwise control user's DNS records. This is done to prevent a malicious web page from executing existing files on a user's computer. It also implements additional checks within the web notifier. WinRAR uses https instead of http in the web notifier window, home page and themes links. We are thankful to Jacob Thompson - Mandiant Advantage Labs for reporting this issue.Ģ. We already prohibited extracting contents of such malformed archives in WinRAR 6.01. It is done to prevent possible attacks with inclusion of ZIP archive into the signature body. ZIP SFX module refuses to process SFX commands stored in archive comment if such comment is resided after beginning of Authenticode digital signature.
