Hash algorithm, английский
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.
Information alert, английский
An alert that indicates that the data source and its protected namespace elements are doing well. examples of these types of messages are the completion (either successful or not) of long running tasks that would normally be followed by further action on the part of the administrator or interesting changes in the namespace (for example, new shares or volumes on protected servers).
