Holds a hash digest and provides from string / to string conversion and comparison. The kAny algorithm may not be used in functions! The algorithm has to be changed beforehand. This class is not used directly, but used as base clase of Md5, Sha1, ...

The alternative path is used to symlink the root catalog from the webserver root to the data directory. This way, the data directory can be protected while the root catalog remains accessible.

Generate the standard relative path from the hexified digest to be used in CAS areas or cache directories. Throughout the entire system we use one directory level (first to hex digest characters) for namespace splitting. Note: This method appends the internal hash suffix to the path.

Generates an arbitrary path representation of the digest. Both number of directory levels and the hash-digits per level can be customized. Further- more an arbitrary hash suffix can be provided. Note: This method is mainly meant for internal usage but stays public for historical reasons.
| dir_levels | the number of namespace splitting directory levels |
| digits_per_level | each directory level's number of hex-digits |
| hash_suffix | the hash suffix character to be appended |

Produces a relative path representation of the digest without appending the hash suffix. See Digest<>::MakePath() for more details.
