# 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 :-)
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
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.
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
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
30
# 27-Apr-98 snh Translation into perl, fix existing CA bug.

# default openssl.cnf file has setup as per the following
