83 | * The current 64-bit, non-cryptographic hash used here is intended | |

85 | * | |
86 | * However, the invariant being prototyped is that objects be | |
87 | * identifiable by their hash components alone. We believe this can | |
88 | * be legitimately implemented using 128-hash values for bucket and | |
89 | * object components, together with a cluster-resident cryptographic | |
90 | * key. Since an MD5 or SHA-1 key is 128 bits and the (fast), | |
91 | * non-cryptographic CityHash128 hash algorithm takes a 128-bit seed, | |
92 | * speculatively we could use that for the final hash computations. | |
