   5     [gentls_cert] Update message digest
   6
   7     Debian Buster updated /etc/ssl/openssl.cnf to default to
   8
   9     MinProtocol = TLSv1.2
  10     CipherString = DEFAULT@SECLEVEL=2
  11
  12     gentls_cert currently uses SHA1 as message digest. According to OpenSSL
  13     documentation this only offers 80 bit of security. 80 bits is enough for
  14     security level 1, but not 2.
  15
  16     The OpenSSL default MD nowadays is SHA256. This commit updates
  17     gentls_cert to use it.
  18
  19     Issue was reported on the FS mailing list. The certificates created by
  20     gentls_cert caused "md too weak" errors and clients were unable to
  21     connect.
