You will now have a Private Key and CSR, the CSR contents are used to submit the request to Entrust to issue the certificate. … It can encrypt the data packet even before it leaves your computer. Assuming you have access to a Linux server with OpenSSL you can easily and quickly generate the private key and certificate request with very little hassle. Now let’s generate a SHA 256 certificate request using the private key we generated above. openssl genrsa -out key.pem 2048 openssl req -new-sha256-key key.pem -out csr.csr openssl req -x509-sha256-days 365 -key key.pem -in csr.csr -out certificate.pem openssl req -in csr.csr -text-noout | grep-i "Signature. And then use something like this to force it to use the public key I want when making the certificate. During the generation of the CSR, you are prompted for several pieces of information. technology, networking, virtualization and IP telephony. Filed Under: Linux Tagged With: ASA, CERTIFICATE, Cisco, CSR, OPENSSL, PEM, PKCS12, SHA256, SSL. ”, https://www.cisco.com/c/en/us/support/docs/security-vpn/public-key-infrastructure-pki/200339-Configure-ASA-SSL-Digital-Certificate-I.html. Step 3: Generating a Self-Signed Certificate  As mentioned above, you must send the CSR to Certificate Authority, such as Verisign, that verifies the identity of the requestor and issues a signed certificate.Or you can use self-sign the CSR if you either do not plan to have your certificate signed by a CA or you want to just test it only while the CA is signing your certificate.This example uses a self-signed certificate method by using the openssl tool to generate a temporary certificate that generates an error in the client browser to the effect that the signing certificate authority is unknown and not trusted. We need to generate the following pieces: Let’s start by creating a directory just for this specific certificate, makes it easier to track all the files we’ll have when we’re complete. b) This command prompts for the following X.509 attributes of the certificate.Enter appropriate information based on the environment; for example: Country Name (2 letter code) [GB]: For example: US or CA.State or Province Name (full name) [Berkshire]: For example: CaliforniaLocality Name (eg, city) [Newbury]: For example: BerkeleyOrganization Name (eg, company) [My Company Ltd]: For example: BlueCoatOrganizational Unit Name (eg, section) []:For example: ITCommon Name (eg, your name or your server's hostname) []:For example: bluecoat.comEmail Address []:For example: [email protected]Please enter the following 'extra' attributesto be sent with your certificate requestA challenge password []:An optional company name []: c) The server.csr generates in Blue Coat Reporter 9\utilities\ssl and you can use this CSR to submit to CA to issue a signed certificate.

If you generate the csr in this way, openssl will ask you questions about the certificate to generate like the organization details and the Common Name (CN) that is the web address you are creating the certificate for, e.g mydomain.com. In this Openssl tutorial session, I will take you through the steps to generate and install certificate on Apache Server in 8 Easy Steps. Since we’re working with a Cisco ASA we need to combine the private key, certificate and any intermediate certificate authorities into a single PKCS12 file so we can upload that file into our Cisco ASA. Note: Replace “server” with the domain name you intend to secure. openssl req -new -newkey rsa:2048 -nodes -out request.csr -keyout private.key. CSRs can be used to request SSL certificates from a certificate authority. This will fire up OpenSSL, instruct it to generate a certificate signing request, and let it know to use a key we are going to specify – the one we just created, in fact.Note that a certificate signing request always has a file name ending in .csr. If it uses encrypted key, openssl asks for  pass phrase.a) Double-click the openssl tool under Blue Coat Reporter 9\utilities\ssl and enter the following command:openssl >genrsa -des3 -out server.key 1024 oropenssl >genrsa -des3 -out server.key 2048 b) After pressing Enter, you are asked to enter a pass phrase for the server.key. However in some cases you may prefer to generate the CSR outside of the appliance and get it signed by the CA. OpenSSL CSR Wizard.
