[%CFEngine_function_prototype(filename, algorithm, hash)%]

Description: Compute the hash of file filename using the hash algorithm and test if it matches hash.

[%CFEngine_function_attributes(filename, algorithm, hash)%]

hash is an ASCII representation of the hash for comparison.

{
classes:

  "matches" expression => hashmatch("/etc/passwd","md5","c5068b7c2b1707f8939b283a2758a691");

  matches::

    "File has correct version";

}
