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 ... 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#
15#
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'.
24# 18-Apr-96 tjh    Original hacking
