http://stackoverflow.com – I'm new in linux. Recently we were asked to enable SSL for one of our projects in the sandbox, and I did using with the following command: yum install mod_ssl openssl openssl genrsa -out ca.key 2048 openssl req -new -key ca.key -out ca.csr openssl x509 -req -days 365 -in ca.csr -signkey ca.key -out ca.crt cp ca.crt /etc/pki/tls/certs cp ca.key /etc/pki/tls/private/ca.key cp ca.csr /etc/pki/tls/private/ca.csr When we need to deploy the product, we need a valid/trusted certificate so one of our guys bought the certificate using my actual CSR file. What I got from him is a .CER file, i thou (HowTos)

I'm trying to generate a CSR with godaddy.

php, openssl and GOST 8 weeks 5 days ago

I'm trying to sign an S/MIME with PHP, using a pair of GOST-encrypted certificate and a private key.

When using openssl itself from a console everything is fine:

/usr/local/openssl/bin/openssl cms -sign -in file.txt -out signedfile.txt -signer p12.pem (signedfile.txt is created)

/usr/local/openssl/bin/openssl cms -verify -in signedfile.txt -out signedddata.txt -no_signer_cert_verify -issuer_che

hi folks,

I have Apache 2.2.8 running on Red Hat Enterprise Linux Server release 5 (Tikanga).

I have installed a purchased certificate on my server. Upon restarting httpd, I get the following error:

# /etc/init.d/httpd start Apache/2.2.8 mod_ssl/2.2.8 (Pass Phrase Dialog)

We went through the steps of revoking an SSL Certificate used by our OpenLDAP server and renewing it but we are unable to start slapd.

Here are the commands we used:

openssl verify hostname_domain_com_cert.pem

We got back that the certificate was expired but "OK"

We revoked the certificate we'd been using:

openssl ca -revoke /etc/ssl/certs/hostname_domain_com_cert.pem

Revoking worked

Windows XP keeps using the snakeoil certificate that Ubuntu shipped with, despite the fact that it has never been used in any virtual host ever.

The certificate is located at

/etc/ssl/certs/ssl-cert-snakeoil.pem

I'm not sure where the key is.

I have a valid certificate installed on a server and when using the -CApath option with OpenSSL, the certificate chain is valid. However if I don't provide the -CApath option I receive this:

19:self signed certificate in certificate chain

When I try Google's HTTPS port without -CApath, OpenSSL returns:

20:unable to get local issuer certificate

What's the difference between the two?

I installed an recompiled both Apache and PHP5, but it seems I am doing something wrong and unable to omit the old openssl. How can I configure and recompile to use only the new one?

From my phpinfo():

Apache/2.4.2 (Unix) OpenSSL/0.9.8o

OpenSSL support enabled OpenSSL Library Version OpenSSL 0.9.8o 01 Jun 2010 OpenSSL Header Version OpenSSL 1.0.1 14 Mar 2012

I have a confusion to choose the best way for upgrading the OpenSSL on my Linux machine.

1*Through the yum Update.*

# yum update

I know this will update the entire packages. But If I want to specifically update OpenSSL

Can I use # yum update OpenSSL

Hello,

I'm trying to decode an IV and a session key that are encrypted with my private key.
