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

# Tim Hudson

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

# demoCA ... where everything is stored cp_pem() {
