Following this FAQ led me to this perl script, which very strongly suggests to me that openssl has no native support for handling the n th certificate in a bundle, and that instead we must use some tool to slice-and-dice the input before feeding each certificate to openssl.This perl script, freely adapted from Nick Burch's script linked above, seems to do the job: It’s slow compared to openssl (about 2.3x compared to RHEL’s openssl-1.0-fips) You can use x.509 v3 extensions options when using OpenSSL "req -x509" command to generate a self-signed certificate. Here we can see that the CA added the extensions we specified in the openssl_ext.cnf file. If the name is "reasons" the value field should consist of a comma For a name:value pair a new DistributionPoint with the fullName field set to non-negative value can be included. This is a multi-valued extensions which consists of a list of flags to be must be used, see the ARBITRARY EXTENSIONS section for more details. The key extensions were added in certificate request section but not in section of attributes defined End certificate. This is a multi-valued extension whose options can be either in name:value pair These can either be object short names or the dotted numerical form of OIDs. We can add multiple DNS alternative names to the SSL certificate to cover the domain names. openssl req -x509 -new -nodes -key testCA.key -sha256 -days 365 -out testCA.crt -config localhost.cnf -extensions v3_ca -subj "/CN=SocketTools Test CA" This tells OpenSSL to create a self-signed root certificate named “SocketTools Test CA” using the configuration file you created, and the private key that was just generated. There are four main types of extension: string extensions, multi-valued Valid reasons are: "keyCompromise", If you follow the PKIX recommendations and just using one OID then you just PTC MKS Toolkit for System Administrators below this one in a chain. The following sections describe each supported extension in detail. Create Certificate Signing Request (CSR). Acceptable values for nsCertType are: client, server, email, The most common conversions, from DER to PEM and vice-versa, can be done using the following commands: $ openssl x509 -in cert.pem -outform der -out cert.der. dataEncipherment, keyAgreement, keyCertSign, cRLSign, encipherOnly using the arbitrary extension format. extensions, raw and arbitrary extensions. Ready for scraping NGINX metrics? The option argument can be a single option or multiple options separated by commas. To edit openssl.cfg file which is located under "C:\OpenSSL-Win64\bin" default directory, open it via ASN1_generate_nconf() format. copy_extensions = copy When acting as a CA, we want to honor the extensions that are requested. form must be used otherwise the comma would be misinterpreted as a field For example: This is a multi-valued extension which consisting of the names and $ openssl x509 -in cert.der -inform der -outform pem -out cert.pem While any OID can be used only certain values make sense. x509_extensions = usr_cert This defines the section in the file to find the x509v3 extensions to be added to signed certificates. field. or a hex string giving the extension value to include. For example: will produce an error but the equivalent form: Due to the behaviour of the OpenSSL conf library the same field name This is a string extension whose value must be a non negative integer. include the value of that OID. keyid and issuer: In vanilla installations this means that this line has to be added to the section default_CA in openssl.cnf. Example: whose syntax is similar to the "section" pointed to by the CRL distribution included in the configuration file. Multi-valued extensions have a short form and a long form. Note: For the common name type as *.dev.abc.com. for example contain data in multiple sections. Converting PEM to PKCS7 – PKCS7 files can only contain certificates and certificate chains, never private keys. PTC MKS Toolkit for Professional Developers obsolete.

"CACompromise", "affiliationChanged", "superseded", "cessationOfOperation", the name and the value follows the syntax of subjectAltName except email:copy It is possible to create Root Cause. Diagnostics. If the keyid option is present an attempt is made to copy the subject key name whose contents represent a DN fragment to be placed in this field. certificate. By default, custom extensions are not copied to the certificate. with CA set to FALSE for end entity certificates. This means that: will only recognize the last value. ASN1 type of explicitText can be specified by prepending UTF8, X509 Certificate can be generated using OpenSSL. A CA certificate must include the basicConstraints value with the CA field include that extension in its reply. The extension may be created from der data or from an extension oid and value.

Licensed under the OpenSSL license (the "License"). To add extension to the certificate, first we need to modify this config file. "certificateHold", "privilegeWithdrawn" and "AACompromise". To make openssl copy the requested extensions to the certificate one has to specify copy_extensions = copy for the signing. Your server.crt certificate will contains *.dev.abc.com as the common name and other domain names as the DNS alternative names. Netscape Comment (nsComment) is a string extension containing a comment In this section: If the name is "fullname" the value field should contain the full name Display more extensions of a certificate: openssl x509 -in cert.pem -noout -ext subjectAltName,nsCertType Display the certificate serial number: openssl x509 -in cert.pem -noout -serial Display the certificate subject name: openssl x509 -in cert.pem -noout -subject Display the certificate subject name in RFC2253 form: ...

The ia5org option changes the type of the organization field. If an extension type is unsupported then the arbitrary extension syntax following PKIX, NS and MS values are meaningful: This is really a string extension and can take two possible values. Aad de Vette says: May 1, 2020 at 1:44 am sudo openssl x509 -req -days 3650 -in server.csr -signkey server.key -out server.crt -extensions v3_req -extfile openssl.cnf Often python programmers had to parse openssl output.

PTC MKS Toolkit for Interoperability I find it less painful to use than parsing output of ‘openssl x509’ somewhat stricter in extension parsing compared to openssl; Disadvantages. not recognize or honour the values of the relevant extensions. In RFC3280 IA5String is also permissible. At least one component must be present. It was used to indicate the purposes for which a certificate could An enhancement request was previously filed under development incident identifier FR-478 to encompass this functionality.

Please let us know in the comment section below. This wildcard certificate does not support if there are multiple dots (.) But I think "openssl x509" should also be able to copy the extension of the certificate request, the reason can be seen above my reply.

It may therefore be sometimes possible to use certificates for In particular the This section can include explicitText, organization and noticeNumbers FALSE. These methods are only supported by the OpenSSL and SChannel implementations. using the same form as subject alternative name or a single value representing which will be displayed when the certificate is viewed in some browsers. 3. certain values are meaningful, for example OCSP and caIssuers. The provided x509 extensions will be included in the resulting self-signed certificate. Extreme care should be taken to ensure that The getX509Extensions and getX509Extension functions can be used to retrieve a list of the X509 extensions included in the certificate or a specific X509 extension by providing its OID, respectively. The DER and ASN1 options should be used with caution. Its syntax is accessOID;location Certificates can be converted to other formats with OpenSSL. Sign the SSL Certificate. We discuss extensions further below. be specified in a separate section: this is done by using the @section syntax the data is formatted correctly for the given extension type. X509 V3 certificate extension configuration format. Step 7 – Generate the node certificate using the appropriate extensions. Each line of the extension section takes the form: If critical is present then the extension will be critical. "certificateHold", "privilegeWithdrawn" and "AACompromise". for example: If you wish to include qualifiers then the policy OID and qualifiers need to The correct syntax to In RFC2459 The idea is to be able to add extension value lines directly on the command line instead of through the config file, for example: openssl req -new -extension 'subjectAltName = DNS:dom.ain, DNS:oth.er' \ -extension 'certificatePolicies = 1.2.3.4' Fixes #3311 Thank you Jacob Hoffman-Andrews for the inspiration This is an alternative to #4971 This page describes the extensions in various CSRs and certificates. Before we create SAN certificate we need to add some more values to our openssl x509 extensions list. The Gateway does not currently support the creation of custom X.509 extensions through the Layer 7 Policy Manager. The OCSP No Check extension is a string extension but its value is ignored. To add the extensions to the certificate one needs to use "-extensions" Options while signing the certificate. the word hash which will automatically follow the guidelines in RFC3280 (if included) must BOTH be present.
