HashSignaturen
HashSignaturen, also known as cryptographic hashes or digital signatures based on hashing, are a fundamental concept in modern cryptography and computer security. They are used to verify the integrity and authenticity of digital data. A hash function takes an input of any size and produces a fixed-size output, known as a hash value or digest. This process is designed to be a one-way function, meaning it is computationally infeasible to reverse the process and derive the original data from its hash.
The key properties of a good cryptographic hash function are: determinism (the same input always produces the
In the context of digital signatures, a sender first computes the hash of a message. This hash
