digest) from a variable length message input. Most hash algorithms have a
|
||||
state which is updated by the hash core function from a block of fixed size
|
||||
from the message. A "lastBlock" function is used to add the last block which
|
||||
is not required to have the fixed length. An addition function is then used
|
||||
to transform the state into the final hash value.
|

||||
Implemented hash functions:

\subsection MACs Message-Authentification-Codes (MACs)
|
||||
Message-Authentification-Codes work like hash function but take an additional
|
||||
key. The produced output is also called MAC and is highly dependant on the
|
||||
key. They can be thought of symmetric signatures.
|
||||

Implemented MAC functions:

\subsection PRNGs Pseudo-Random-Number-Generators (PRNGs)
|
||||
PRNGs produce pseudo random output determinated by the input. They aim to
|
||||
produce an arbitrary length of good cryptographically secure random if the
|
||||
input has enough entropy. PRNGs differ in the way they accept input. Some
|
||||
are seeded only once, other (like the implemented) maintain an entropy pool
|
||||
to which input can be added at virtually any time.
|
||||
