New Certification Authority - CA


Primeiramente gostaria de salientar que não sou o autor principal do conteúdo deste artigo. A minha intenção é de mostrar o que outros autores tem realizado (referenciando links para o conteúdo original) neste blog até como um guia pessoal para uso próprio e ainda compartilhar minhas anotações e pequenas modificações que realizo no conteúdo, desejando que possa ajudar mais alguém em algum lugar.
First and foremost, I take no credit for any of this post’s content. I am really just taking what others have done (which I have links to bellow) and am putting it on my blog for a personal reference and hopefully the small changes that I made to their guides will help someone somewhere.

Script baseado no arquivo /usr/lib/ssl/misc/CA.sh do pacote openssl_1.0.1e-2_i386.deb da distribuição do debian wheezy abaixo:

#!/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
