This thesis concerns with hash functions and their usage in authentication. It presents basics of hash functions theory and construction elements. In particular the thesis focuses on LMHash, MD4, MD5 and SHA family hash functions, which are compared from the security point of view. The thesis describes in general the most frequently used hash function attacks, points out the weaknesses of current construction and mentions the future perspective of hash functions. Furthermore the thesis outlines the area authentication and describes usage of hash functions in the area. Practical part of the thesis contains an implements of a general authentication framework implemented in programming language C#.
