Construct a hash filter.

len | the output length of this filter. Leave the default value 0 if you want to use the full output of the hashfunction hash. Otherwise, specify a smaller value here so that the output of the hash algorithm will be cut off. |

request | the name of the hash algorithm to use |
len | the output length of this filter. Leave the default value 0 if you want to use the full output of the hashfunction hash. Otherwise, specify a smaller value here so that the output of the hash algorithm will be cut off. |
