Password Recovery of RAR, BZIP, and GZIP Archives Using GPU
Mikuš, Dávid ; Holkovič, Martin (referee) ; Hranický, Radek (advisor)
This thesis describes cryptographic protection and the implementation of file password of RAR, GZIP, BZIP formats. For password recovery multi platform Wrathion tool is used, the tool can obtain a password from an encrypted file by using its modules and password generators. The module provides parsing of input file and storing data, which are later used for password validation. To accelerate calculations, graphics card and OpenCL framework is used. The core of thesis is the implementation of Wrathion's modules for password recovery of the formats denoted above and measuring the speed and comparision with competeting tools.
Analysis of the Possibility of Password Break through for RAR, ZIP and 7z Formats
Prustoměrský, Milan ; Přikryl, Zdeněk (referee) ; Hruška, Tomáš (advisor)
This Thesis deals with analysis of the possiblity of password breakthrough for common compression formats and password extraction from self-extraction archives used for malicious software. Structure of compression programs, ciphers and connection between cipher and archives is described. Common and specialized attacks on archives and ciphers are described. Structure of self-extracting archives and password location is used to create extractor of passwords in self-extracting archives.
