OpenSSL. The following sections describe how to use OpenSSL to generate a CSR for a single host name. If you want to generate a CSR for multiple host names, we recommend using the Cloud Control Panel or the MyRackspace Portal. Install OpenSSL. Check whether OpenSSL is installed by using the following command: CentOS® and Red Hat® Enterprise
The basicConstraints, keyUsage and extended key usage extensions are now used instead. Acceptable values for nsCertType are: client, server, email, objsign, reserved, sslCA, emailCA, objCA. Arbitrary Extensions. If an extension is not supported by the OpenSSL code then it must be encoded using the arbitrary extension format. Self-signed certificates and keyUsage extension. Must non-CA, self-signed certificates have the "keyCertSign" bit set in the keyUsage extension to be "valid?" If I don't have the bit set and execute # See the POLICY FORMAT section of the `ca` man page. countryName = optional stateOrProvinceName = optional localityName = optional organizationName = optional organizationalUnitName = optional commonName = supplied emailAddress = optional [req ] # Options for the `req` tool (`man req`). default_bits = 2048 distinguished_name = req Jun 23, 2020 · openssl genrsa -out dev.deliciousbrains.com.key 2048 Then we create a CSR: openssl req -new -key dev.deliciousbrains.com.key -out dev.deliciousbrains.com.csr You’ll get all the same questions as you did above and, again, your answers don’t matter. Jun 22, 2020 · The official documentation on the openssl_certificate module. openssl_dhparam – Generate OpenSSL Diffie-Hellman Parameters The official documentation on the openssl_dhparam module. openssl_pkcs12 – Generate OpenSSL PKCS#12 archive The official documentation on the openssl_pkcs12 module. openssl_privatekey – Generate OpenSSL private keys I want to use OpenSSL to create a CSR and submit it to my CA (which uses Microsoft PKI) and receive certificates that can be used for both Server Auth and Client Auth. I'm not clear on a couple of things, which may simply be a a link between keyUsage and nsCertType.
# This is typical in keyUsage for a client certificate. # keyUsage = nonRepudiation, digitalSignature, keyEncipherment # This will be displayed in Netscape's comment listbox. nsComment = "OpenSSL Generated Certificate" # PKIX recommendations harmless if included in all certificates. subjectKeyIdentifier=hash: authorityKeyIdentifier=keyid,issuer

#openssl ca -policy policy_anything -config -out windows_server.crt -extensions some_ext -extfile some_extensions.txt -infiles cert_request.csr provided, you have created a file named "some_extensions.txt" on the same directory and it has got the required extensions the windows box required. id-ce-keyUsage This extension indicates the purpose for which the certified public key is used. This extension may, at the option of the certificate issuer, be either critical or non-critical. >> OpenSSL has Key Encipherment (e0) as a Key Usage, while a certificate >> generated through MS Certificate Server has Key Encipherment (a0). > > What do you get in the keyUsage extension when you do: > > openssl x509 -in cert.pem -noout -text > openssl shows "Key Encipherment" for both certifcates. Is the e0/a0 issue a MS undocumented "feature"? Type openssl req -new -key privkey.pem -out request.csr This command generates a CSR in the PEM format in your current working directory. When you are prompted for the x509 Common Name attribute information, type your fully-qualified domain name (FQDN). Use other information as appropriate. # cd /root/ca # openssl req -config openssl.cnf \-key private/ca.key.pem \-new -x509 -days 7300-sha256 -extensions v3_ca \-out certs/ca.cert.pem Enter pass phrase for ca.key.pem: secretpassword You are about to be asked to enter information that will be incorporated into your certificate request.
