-Perl 5.18 we can only recommend use of the default or SIPHASH. All
-the others are known to have security issues and are for research

+Since Perl 5.18 we have included support for multiple hash functions,
+although from time to time we change which functions we support,
+and which function is default (currently SBOX+STADTX on 64 bit builds
+and SBOX+ZAPHOD32 for 32 bit builds). You can choose a different
+algorithm by defining one of the following symbols during configure.
+Note that there security implications of which hash function you choose
+to use. The functions are listed roughly by how secure they are believed
+to be, with the one believed to be most secure at release time being 
PERL_HASH_FUNC_SIPHASH.
 
     PERL_HASH_FUNC_SIPHASH

-Perl 5.18 randomizes the order returned by keys(), values(), and each(),
-and allows controlling this behavior by using of the PERL_PERTURB_KEYS
-option. You can disable this option entirely with the define:
+    PERL_HASH_FUNC_SIPHASH13
+    PERL_HASH_FUNC_ZAPHOD32
+    PERL_HASH_FUNC_STADTX
+
+In addition, these, (or custom hash functions), may be "fronted" by the
+SBOX32 hash function for keys under a chosen size. This hash function is
+special in that it has proven theoretical security properties, and is very
+fast to hash, but which by nature is restricted to a maximum key length,
+and which has rather expensive setup costs (relatively speaking), both in
+terms of performance and more importantly in terms of memory. SBOX32
+requires 1k of storage per character it can hash, and it must populate that
+storage with 256 32-bit random values as well. In practice the RNG we use
+for seeding the SBOX32 storage is very efficient and populating the table
+required for hashing even fairly long keys is negligble as we only do it
+during startup. By default we build with SBOX32 enabled, but you change that
+by setting
+
+   PERL_HASH_USE_SBOX32_ALSO
+
+to zero in configure. By default Perl will use SBOX32 to hash strings 24 bytes
+or shorter, you can change this length by setting
+
+    SBOX32_MAX_LEN
+
+to the desired length, with the maximum length being 256.
+
+As of Perl 5.18 the order returned by keys(), values(), and each() is
+non-deterministic and distinct per hash, and the insert order for
+colliding keys is randomized as well, and perl allows for controlling this
+by the PERL_PERTURB_KEYS environment setting. You can disable this behavior

+  People who have theories as to how one should live tend to forget the
+  limitations of nature. If your way of life involves constant
+  restraint of impulse for the sake of some one supreme aim that you
+  have set yourself, it is likely that the aim will become increasingly
+  distasteful because of the efforts that it demands; impulse, denied
+  its normal outlets, will find others, probably in spite; pleasure, if
+  you allow yourself any at all, will be dissociated from the main
+  current of your life, and will become Bacchic and frivolous. Such
+  pleasure brings no happiness, but only a deeper despair.
