1 function
"A piece of code that operates as a single logical unit. A function is called by name, accepts optional input parameters, and returns a status and optional output parameters. Many programming languages support functions." -
2 pseudo-random function
"A function that takes a key, label, and seed as input, then produces an output of arbitrary length." -
3 hash function
"An algorithm that produces a hash value of some piece of data, such as a message or session key. With a good hash algorithm, changes in the input data can change every bit in the resulting hash value; for this reason, hashes are useful in detecting any modification in a data object, such as a message. Furthermore, a good hash algorithm makes it computationally infeasible to construct two independent inputs that have the same hash. Typical hash algorithms include MD2, MD4, MD5, and SHA-1." -
4 cryptographic digest
The result of a one-way hash function that takes a variable-length input string and converts it to a fixed-length output string. This fixed-length output string is probabilistically unique for every different input string and thus can act as a fingerprint of a file. It can be used to determine whether a file was tampered with. -
5 hash
"A fixed-size result that is obtained by applying a one-way mathematical function (sometimes called a hash algorithm) to an arbitrary amount of data. If there is a change in the input data, the hash changes. The hash can be used in many operations, including authentication and digital signing." -
6 message digest
"A fixed-size result that is obtained by applying a one-way mathematical function (sometimes called a hash algorithm) to an arbitrary amount of data. If there is a change in the input data, the hash changes. The hash can be used in many operations, including authentication and digital signing." -
7 hash code
"A fixed-size result that is obtained by applying a one-way mathematical function (sometimes called a hash algorithm) to an arbitrary amount of data. If there is a change in the input data, the hash changes. The hash can be used in many operations, including authentication and digital signing." -
8 PRF
"A function that takes a key, label, and seed as input, then produces an output of arbitrary length."
