Table of Contents

Prototype: hash(input, algorithm)

Return type: string

Description: Return the hash of input using the hash algorithm.

Hash functions are extremely sensitive to input. You should not expect to get the same answer from this function as you would from every other tool, since it depends on how whitespace and end of file characters are handled.

Arguments:

  • input: string, in the range: .*
  • algorithm: one of
    • md5
    • sha1
    • sha256
    • sha384
    • sha512

Example:

body common control
{
      bundlesequence => { "example" };
}

bundle agent example

{
  vars:

      "md5" string => hash("Cfengine is not cryptic","md5");
      "sha256" string => hash("Cfengine is not cryptic","sha256");
      "sha384" string => hash("Cfengine is not cryptic","sha384");
      "sha512" string => hash("Cfengine is not cryptic","sha512");

  reports:

      "Hashed to: md5 $(md5)";
      "Hashed to: sha256 $(sha256)";
      "Hashed to: sha384 $(sha384)";
      "Hashed to: sha512 $(sha512)";

}

Output:

R: Hashed to: md5 2036af0ee58d6d9dffcc6507af92664f
