# 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. |

# 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'. |
