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.

Constructor Summary
`SHA256KeyHashingScheme()`

Method Summary
`String` `hash(String key)` Maps a storage key to a cache key.

Constructor Detail

### SHA256KeyHashingScheme

    public SHA256KeyHashingScheme()

Method Detail

### 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
