### About Adler 32 create hash online tool

Adler 32 is a so called checksum algorithm. It produces an Adler-32 output for the value that you enter in the Input window. It was invented by Mark Adler, an American mathematician.

The final checksum is obtained by calculating 2 16 bit checksums, A and B and connecting the bits into a single 32 bit result. In this algorithm, A means the sum of all bytes plus one, B is the total all the values from each step in A. When Adlerr-32 is run, A is 1 and B is 0. The sums are done modulo 65521(which is a prime number, the largest one that does not exceed 216 ) The order in which the bytes are stored is called the big endian, with B occupying 2 most significant bytes. This coding however has some flaws, the most significant of which are the fact that it has a problem with coding short messages and that it can be easily forged. The message length problem was discovered by one Jonathan Stone in 2001. Susceptibility to forgery makes it inefficient when it comes to coding messages that can be intentionally modified.

Produce an Adler-32 output for the value that you enter in the Input window. Adler-32 is a checksum algorithm. It was invented by Mark Adler.

A checksum or hash sum is computed from data to detect errors introduced during transmission or storage. Data integrity is checked by comparing with a stored valued. If the checksums are the same, the data was probably not altered.

Checksum is related to hash functions. A checksum normally is not for security related applications.

Hash keying is also known as convergent encryption. This keying and encryption is a cryptosystem that produces ciphertext from plain text.

Cloud computer is one area where hash keying has an application. This is because with hash keying you complete operations without giving the provider access to encryption tools. This process was developed in the mid 1990’s. In 2011 Bitcasa – a cloud storage provider

announced use of hash keying, giving the system promotion. A cryptographic hash function is an algorithm that takes data and provides a hash value. The message or value to be encoded is the data while the hash value is called a digest or message digest.

The cryptographic hash function has several important properties. One property is that it is easy to compute the hash value. Another property is that it is not feasible to generate a message with a hash. Another is that it is not feasible to modify the message and not change the hash. Finally, it is not feasible to have the same hash for different messages.

Authentication and digital signatures are two of many information security applications involving cryptographic hash. The hash functions can also be useful for fingerprinting, identification of duplicate data, detection of data corruption, and creation of hash tables. Cryptographic hash values are sometimes called hash values or checksums or digital fingerprints. Security provided by a hash algorithm depends on it being able to produce a unique value. A collision occurs when you get the same hash value for different data. A strong hash value is resistant to computational attacks. With a weak hash it could be possible to produce a collision. A broken hash is where collisions occurred.
