<para>
This function does not generate cryptographically secure values, and <emphasis>must not</emphasis>

</para>
<para>
If cryptographically secure randomness is required, the <classname>Random\Randomizer</classname> may be
used with the <classname>Random\Engine\Secure</classname> engine. For simple use cases, the <function>random_int</function>
and <function>random_bytes</function> functions provide a convenient and secure <acronym>API</acronym> that is backed by
the operating system’s <acronym>CSPRNG</acronym>.
</para>
</caution>'>
<!ENTITY caution.mt19937-tiny-seed '<caution xmlns="http://docbook.org/ns/docbook">
<para>
Because the Mt19937 (“Mersenne Twister”) engine accepts only a single 32 bit integer as the
seed, the number of possible random sequences is limited to just 2<superscript>32</superscript>
(i.e. 4,294,967,296), despite Mt19937’s huge period of 2<superscript>19937</superscript>-1.
</para>
<para>
When relying on either implicit or explicit random seeding, duplications will appear
much earlier. Duplicated seeds are expected with 50% probability after less than
80,000 randomly generated seeds according to the birthday problem. A 10% probability
of a duplicated seed happens after randomly generating roughly 30,000 seeds.
</para>
<para>
This makes Mt19937 unsuitable for applications where duplicated sequences must not happen with
more than a negligible probability. If reproducible seeding is required, both the
<classname>Random\Engine\Xoshiro256StarStar</classname> and <classname>Random\Engine\PcgOneseq128XslRr64</classname>
engines support much larger seeds that are unlikely to collide randomly. If reproducibility
is not required, the <classname>Random\Engine\Secure</classname> engine provides cryptographically
secure randomness.

When using versions of the GD library lower than 2.0.18, a <literal>space</literal> character,
rather than a semicolon, was used as the 'path separator' for different font files.
Unintentional use of this feature will result in the warning message:
