Re: OpenSSL Ca

Hi Anton,

I don't know if my article can help you, but you can find what I wrote
here about OpenSSL CA and Thunderbird (I am sorry for my poor English)
here: http://www.homeworks.it/Html/OpenSSL_PKI_Articolo_Eng.html#InstEMailCert

Bye,

Alex

Hi,
  
  
  I'm trying to create a private CA with openssl for my
enterprise. I have generated the CA private key and certificate. I have
created a key pair and a certificate signing request from a windows pc
using kleopatra (key management utility that comes with winpgp). I
signed the request with the CA's key and sent the signed certificate to
the windows pc and imported the certificate. I exported the public key
which I sent to my laptop. I imported the certificate of my CA into my
mail client and trusted it. I then imported the public key as exported
from the windows pc. It is imported but instead of being put into the
People category it's sent in the Others section as it apparently does
not fit in any of the other categories. I am therefore unable to send
encrypted mail to the windows pc using it's public key as my client
will not use it to encrypt.
  
  
  The following are the commands I used in order to get to this
point:
  
  
  In order to generate the private key and ca certificate:
  
  
  # openssl req -config openssl.my.cnf -new -x509 -extensions
v3_ca -keyout private/myca.key -out certs/myca.crt -days 1825
  
  
  I converted the request from DER to PEM format using:
  
  
  openssl
req -in datareq.p10 -inform der -out datareq.csr
  
  
  In order to sign the request:
  
  
  # openssl ca -config openssl.my.cnf -policy policy_anything -in
datareq.csr
  
  
  I'm at a loss at the moment so any help would be appreciated.
  
  
  Thanks ,
  
  
  Anton

Article on PKI and OpenSSL

2008-09-30 Thread Alessandro Tani

Hello,

my name is Alessandro Tani, together with my colleague Iarno Pagliani, 
we made a guide 
(http://www.homeworks.it/Html/OpenSSL_PKI_Articolo_Eng.html) on how to 
create a PKI infrastructure with OpenSSL on Debian platform, to provide 
digital certificates for programs like Postfix, Courier, Apache and 
people to be able to digitally sign and encrypt their emails. We'd love 
to know your opinion about the article we have achieved. We apologize 
right now for our English, if you find errors or inaccuracies, both in 
the article and in the language, we would be very grateful if you could 
have the report. We will immediately fix the inaccuracies.


You can find our article on URL: 
http://www.homeworks.it/Html/OpenSSL_PKI_Articolo_Eng.html


Thank you very much,

Alessandro Tani

How to insert a particular x509v3 extension

2008-05-04 Thread Alessandro Tani

Hi,

I would like to add a particular x509v3 extension to a certificate 
PKCS#12 to sign email address, the particular extension is Object 
Identifier followed by an OID number. For example:


Object Identifier (2.16.840.1.113733.1.6.10)

The OID 2.16.840.1.113733.1.6.10 is an example inspired by VeriSign.

Thank you very much,

Alex
