Applications . Cryptocurrency: Cryptographic hash functions are widely used in cryptocurrencies to pass transaction information anonymously.For example, Bitcoin uses the SHA-256 cryptographic hash ...

Hash functions are algorithms that determine how information is encrypted. For example, Secure Hashing Algorithm 256 (SHA-256) goes through a process to encrypt the input it receives by: ...

Perceptual hash functions are designed to return answers for images or sounds that a human might feel are similar. That is, small changes in the media don’t affect the output.

Additionally, a hash is supposed to be unique: no two (different) pieces of data should result in the same hash. If either of these things is no longer true, a hash function is considered to be broken ...

Hashing is a one-way cryptographic function while encryption is designed to work both ways. Encryption algorithms take input and a secret key and generate a random looking output called a ...

Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature.

For more than six years, the SHA1 cryptographic hash function underpinning Internet security has been at death's door.Now it's officially dead, thanks to the submission of the first known instance ...

Hash functions are cryptography’s most widely used primitives, in that they are a fundamental building block used for a wide variety of constructions. The recent attacks of Joux, ...
