   3 # CA - wrapper around ca to make it easier to use ... basically ca requires
   4 #      some setup stuff to be done before you can use it and this makes
   5 #      things easier between now and when Eric is convinced to fix it :-)
   6 #
   7 # CA -newca ... will setup the right stuff
   8 # CA -newreq[-nodes] ... will generate a certificate request
   9 # CA -sign ... will sign the generated request and output
  10 #
  11 # At the end of that grab newreq.pem and newcert.pem (one has the key
  12 # and the other the certificate) and cat them together and that is what
  13 # you want/need ... I'll make even this a little cleaner later.
  14 #

  16 # 12-Jan-96 tjh    Added more things ... including CA -signcert which
  17 #                  converts a certificate to a request and then signs it.
  18 # 10-Jan-96 eay    Fixed a few more bugs and added the SSLEAY_CONFIG
  19 #                  environment variable so this can be driven from
  20 #                  a script.
  21 # 25-Jul-96 eay    Cleaned up filenames some more.
  22 # 11-Jun-96 eay    Fixed a few filename missmatches.
  23 # 03-May-96 eay    Modified to use 'ssleay cmd' instead of 'cmd'.
