84 | * | |
85 | * However, the invariant being prototyped is that objects be | |

87 | * be legitimately implemented using 128-hash values for bucket and | |
88 | * object components, together with a cluster-resident cryptographic | |
89 | * key. Since an MD5 or SHA-1 key is 128 bits and the (fast), | |
90 | * non-cryptographic CityHash128 hash algorithm takes a 128-bit seed, | |
91 | * speculatively we could use that for the final hash computations. | |
