Class SHA256KeyHashingScheme

java.lang.Object
  org.apache.http.impl.client.cache.memcached.SHA256KeyHashingScheme

All Implemented Interfaces:

KeyHashingScheme

public class SHA256KeyHashingScheme
extends Object
implements KeyHashingScheme

This is a KeyHashingScheme based on the SHA-256 algorithm. The hashes produced are hex-encoded SHA-256 digests and hence are always 64-character hexadecimal strings.

hash

public String hash(String key)

Description copied from interface: KeyHashingScheme

Maps a storage key to a cache key. The storage key is what the higher-level HTTP cache uses as a key; the cache key is what we use as a key for talking to memcached.

Specified by:

hash in interface KeyHashingScheme

Parameters:

key - what the higher-level HTTP cache wants to use as its key for looking up cache entries

Returns:

a cache key suitable for use with memcached
