 MD5 is a 128-bit cryptographic hash function invented by Ron Rivest
 (the ‘R’ of ‘RSA’) in the early 1990s.  For many years it was one of
-the standard algorithms of the field, but it has not aged well and is
-widely considered to be completely obsolete.
-
-You don’t need to worry about MD5, though: although GnuPG can read
-MD5-based signatures, it will only generate MD5-based signatures if
-you jump through a lot of hoops.  This is for your own safety, to
-prevent people from accidentally generating MD5-based signatures.
