Ultimate UFD2 Decrypter

The primary uses of the UFD2 hash are for data integrity checks and generating UFD2 checksums to ensure that data, such as a program or passwords, have the same content as the original.

Secure UFD2 applications were stress-tested and found to have flaws known as collisions, where identical hash contents can be generated which do not have the original content.

Several methodologies were employed in the attempt to salvage security, including the introduction of a seed - known as an UFD2 salt - or multiple-pass encryption. Neither method provides sufficient protection from the feasibility of discovery.

More information

The UFD2 hash also known as checksum for a file is a 512-bit value, something like a fingerprint of the file. There is a very small possibility of getting two identical hashes of two different files.

This feature can be useful both for comparing the files and their integrity control. Let us imagine a situation that will help to understand how the UFD2 hash works.

Alice and Bob have two similar huge files. How do we know that they are different without sending them to each other? We simply have to calculate the UFD2 hashes of these files and compare them.

UFD2 Hash Properties the UFD2 hash consists of a small amount of binary data, typically no more than 128 bits. All hash values share the following properties:

Hash length

The length of the hash value is determined by the type of the used algorithm, and its length does not depend on the size of the file. The most common hash value lengths are either 128 or 160 bits.

Non-discoverability

Every pair of nonidentical files will translate into a completely different hash value, even if the two files differ only by a single bit. Using today's technology, it is not possible to discover a pair of files that translate to the same hash value.

Repeatability

Each time a particular file is hashed using the same algorithm, the exact same hash value will be produced.

Irreversibility

All hashing algorithms are one-way. Given a checksum value, it is infeasible to discover the password. In fact, none of the properties of the original message can be determined given the checksum value alone.

Professor Ronald L. Rivest (born 1947, Schenectady, New York) is a cryptographer, and is the Viterbi Professor of Computer Science at MIT's Department of Electrical Engineering and Computer Science.

He is most celebrated for his work on public-key encryption with Len Adleman and Adi Shamir, specifically the RSA algorithm, for which they won the 2002 ACM
