&lt;p&gt;brcypt is not available in libc's crypt() method on Debian 9. I would like to have used it for dovecot password storage (&lt;a class="reference external" href="https://wiki2.dovecot.org/Authentication/PasswordSchemes"&gt;https://wiki2.dovecot.org/Authentication/PasswordSchemes&lt;/a&gt;).&lt;/p&gt;
&lt;p&gt;Reasons:&lt;/p&gt;
&lt;ul class="simple"&gt;
&lt;li&gt;Debian does not want to differ from upstream glibc (&lt;a class="reference external" href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=149452"&gt;https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=149452&lt;/a&gt;)&lt;/li&gt;
&lt;li&gt;glibc does not want to include it because it is not on the list of NIST-recommended algorithms&lt;ul&gt;
&lt;li&gt;&lt;a class="reference external" href="https://sourceware.org/bugzilla/show_bug.cgi?id=2100"&gt;https://sourceware.org/bugzilla/show_bug.cgi?id=2100&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a class="reference external" href="https://akkadia.org/drepper/sha-crypt.html"&gt;https://akkadia.org/drepper/sha-crypt.html&lt;/a&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;/li&gt;
&lt;/ul&gt;
&lt;p&gt;We shall use SHA-512 instead.&lt;/p&gt;
&lt;/div&gt;

 &lt;/div&gt;
