str: parser name type: next hasher class.
-
classmethod
GetHasherNames
()[source]¶ Retrieves the names of all loaded hashers.
Returns: hasher names. Return type: list[str]
-
classmethod
GetHasherNamesFromString
(hasher_names_string)[source]¶ Retrieves a list of a hasher names from a comma separated string.
Takes a string of comma separated hasher names transforms it to a list of hasher names.
Parameters: hasher_names_string (str) – comma separated names of hashers to enable, the string ‘all’ to enable all hashers or ‘none’ to disable all hashers. Returns: - names of valid hashers from the string, or an empty list if no
- valid names are found.
Return type: list[str]
-
classmethod
GetHashers
(hasher_names)[source]¶ Retrieves instances for all the specified hashers.
Parameters: hasher_names (list[str]) – names of the hashers to retrieve. Returns: hashers. Return type: list[BaseHasher]
-
