RIPEMD create hash online

Complete a RIPEMD output on the Input data. This cryptographic hash function is a message digest algorithm. Short for RACE Integrity Primitives Evaluation Message Digest, it was published first in the mid 1990’s. Unlike the more popular SHA-1 and SHA-2 which were created by the NSA, RIPEMD is a child of an open academic collaboration, created as an European Union project. It was designed to be impenetrable to then existing methods of cryptanalysis.

Choose from the 128, 169, 256, and 320-bit versions from the drop-down. Performance is similar to SHA-1 and design is similar to MD4.

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.
