+Subject: [PATCH] t/op/taint.t: Perform SHA-256 algorithm by crypt() if default
+ one is disabled
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The crypt(3) call may return NULL. This is the case on FIPS-enabled
+platforms. Then "tainted crypt" test would fail.
+
+See RT#121591 for similar fix in t/op/crypt.t.
