CAの内容

 #!/bin/sh
 #
 # CA - wrapper around ca to make it easier to use ... basically ca requires
#      some setup stuff to be done before you can use it and this makes
#      things easier between now and when Eric is convinced to fix it :-)
#
# CA -newca ... will setup the right stuff
# CA -newreq ... will generate a certificate request
# CA -sign ... will sign the generated request and output
#
# At the end of that grab newreq.pem and newcert.pem (one has the key
# and the other the certificate) and cat them together and that is what
# you want/need ... I'll make even this a little cleaner later.
#
#
# 12-Jan-96 tjh    Added more things ... including CA -signcert which
#                  converts a certificate to a request and then signs it.
# 10-Jan-96 eay    Fixed a few more bugs and added the SSLEAY_CONFIG
#                  environment variable so this can be driven from
#                  a script.
# 25-Jul-96 eay    Cleaned up filenames some more.
# 11-Jun-96 eay    Fixed a few filename missmatches.
# 03-May-96 eay    Modified to use 'ssleay cmd' instead of 'cmd'.
# 18-Apr-96 tjh    Original hacking
