Class SHA256KeyHashingScheme

  • All Implemented Interfaces:

    public class SHA256KeyHashingScheme
    extends java.lang.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.

        public java.lang.String hash​(java.lang.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
        key - what the higher-level HTTP cache wants to use as its key for looking up cache entries
        a cache key suitable for use with memcached
