+commit 70d1cbafe4ab0176cd9fc01f740e34cd1bae326b
+Author: Sebastian Kemper <sebastian_ml@gmx.net>

+
+    [gentls_cert] Update message digest
+    
+    Debian Buster updated /etc/ssl/openssl.cnf to default to
+    
+    MinProtocol = TLSv1.2
+    CipherString = DEFAULT@SECLEVEL=2
+    
+    gentls_cert currently uses SHA1 as message digest. According to OpenSSL
+    documentation this only offers 80 bit of security. 80 bits is enough for
+    security level 1, but not 2.
+    
+    The OpenSSL default MD nowadays is SHA256. This commit updates
+    gentls_cert to use it.
+    
+    Issue was reported on the FS mailing list. The certificates created by
+    gentls_cert caused "md too weak" errors and clients were unable to
+    connect.
