A X509 V3 extensions options in the configuration file allows you to add extension properties into x.509 v3 certificate when you use OpenSSL commands to generate CSR and self-signed certificates. It is unclear that -extensions (or x509_extensions) must be used in order to create an x509v3 certificate. https://www.openssl.org/docs/man1.1.1/man1/x509.html. It would be nice to support the existing "copy_extensions = copy" feature also in for "openssl x509". x509_extensions = usr_cert # The extentions to add to the cert # Comment out the following two lines for the "traditional" # (and highly broken) format. Already on GitHub? You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. The file openssl.cnf that comes with the installation contains configuration information used by the openssl commands. If critical is true the extension is marked critical. It's very disappointing. BUGS Please give me a reason. to your account. Ruby is an interpreted object-oriented programming language often used for web development. Download and unzip openSSL tool in an empty directory. Create a configuration file using the vi openssl_ext.conf command. It's probably better to use the openssl ca command... @richsalz OpenSSL "x509 -fingerprint" - Print Certificate Fingerprint How to print out MD5 and SHA-1 fingerprints of a certificate using OpenSSL "x509" command? $ openssl x509 -inform der -in cert.der -out cert.pem Converting Certificate from PEM to DER $ openssl x509 -outform der -in cert.pem -out cert.der Converting Certificate Chain from PKCS #7 to PEM $ openssl pkcs7 -print_certs -in cert_chain.p7b -out cert_chain.pem Decoding Certificate $ openssl asn1parse -in test.pem If critical is true the extension … Note: Netscape communicator chokes on V2 CRLs # so this is commented out by default to leave a V1 CRL. OpenSSL::X509::Extension.new(oid, value, critical) Creates an X509 extension. Have a question about this project? Copy and paste the following OpenSSL commands into the configuration file. 1. 3. Normal certificates should not have the authorisation to sign other certificates. This is very valuable, which avoids the need for a meaningless secondary extension addition in the x509 command and avoids the need to create a separate configuration file for -extfile. In fact, you can also add extensions to "openssl x509" by using the -extfile option. While already supported with "openssl ca", basic signing does not support the "copy_extension" mode. Successfully merging a pull request may close this issue. Sign in This should be done using special certificates known as Certificate Authorities (CA). The text was updated successfully, but these errors were encountered: It is not really a bug, it is a security concern. # crlnumber must also be commented out to leave a V1 CRL. To make openssl copy the requested extensions to the certificate one has to specify copy_extensions = copy for the signing. You can obtain a copy @@ -240,8 +240,9 @@ static int trust_1oid(X509_TRUST *trust, X509 *x, int flags) I need to see them and validate them with the owner of the certificate. extensions = extend [req] # openssl req params . Make the following modifications to the [CA_default] section: Ensure that the line copy_extensions = copy does not have a # at the beginning of the line. prompt = no . Next we set subjectKeyIdentifier to hash - this means the method for finding the SKI is to hash the public key.

These examples are extracted from open source projects. "openssl x509" is a more lightweight certificate operation tool. Extensions in certificates are not transferred to certificate requests and vice versa. By clicking “Sign up for GitHub”, you agree to our terms of service and DESCRIPTION. By clicking “Sign up for GitHub”, you agree to our terms of service and I think it is different from "openssl ca". In fact, you can also add extensions to "openssl x509" by using the -extfile option. Why does the x509 command not copy extension in certificate request. Perhaps one way around this is to add a couple of flags to the ca command. Basic signing might be neccessary when the "openssl ca" magic is too much and cannot be turned off in certain usecases. Create a configuration file using the vi openssl_ext.conf command. extensions = extend [req] # openssl req params . Sign in * this file except in compliance with the License. OpenSSL itself does not copy anyextensions from PKCS #10 requests to X.509 certificates; all extensions for certificates must be explicitly declared. O = VMware (Dummy Cert) OU = Horizon Workspace (Dummy Cert) CN = hostname … X509 V3 extensions options in the configuration file are: Documentation for openSSL tool is available here. The curve objects are useful as values for the argument accepted by Context.set_tmp_ecdh() to specify which elliptical curve should be used for ECDHE key exchange. Have a question about this project? Delete the # if it is there. privacy statement. There isn't a function to get all extensions. WIP : Added first draft of common component for handling certificates and related secrets. 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. X509 Certificate can be generated using OpenSSL. 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. 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. Including v3 extensions via copy_extensions in the config file should also produce an x509v3 certificate. To add extension to the certificate, first we need to modify this config file. The job of a CA is to look at the request and verify all extensions before putting them into the cert. Already on GitHub? Blindly copying extensions without some explicit direction to do so would be an issue -- for example, if the config didn't specify SAN values, but the cert request had them then the cert could be bogus. Several OpenSSL commands can add extensions to a certificate or certificate request based on the contents of a configuration file and CLI options such as -addext. prompt = no . Thus when using "openssl x509" instead, from each CSR, a openssl.config has to be created manually by duplicating the CSR fields before signing, which makes it even more risky and error prone than using the "copy_extensions". In vanilla installations this means that this line has to be added to the section default_CA in openssl.cnf. openssl x509 -outform der -in certificate.pem -out certificate.der Convert a PKCS#12 file (.pfx .p12) containing a private key and certificates to PEM openssl pkcs12 -in keyStore.pfx … Typically the application will contain an option to point to an extension section. We’ll occasionally send you account related emails. privacy statement. The oid may be either an OID or an extension name. The first thing we have to understand is what each type of file extension is. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Get the information and services for the issuer from the certificate's authority information access extension exteension, as described in RFC5280 Section 4.2.2.1. It also offers many scripting features to process plain text and serialized files, or manage system tasks. Obviously only need to add a -copy_extensions option to solve this problem perfectly. The problem encountered by so many people is only because of a small bug here. The text was updated successfully, but these errors were encountered: Successfully merging a pull request may close this issue. X509 V3 certificate extension configuration format . The following are 30 code examples for showing how to use OpenSSL.crypto.X509Extension (). Support "copy_extensions" also with x509 CSR signing. In the above section all the x509 extension that are required should be specified in usr_cert section in openssl.cnf [ usr_cert ] basicConstraints=CA:FALSE nsCertType = client, server, email keyUsage = nonRepudiation, digitalSignature, keyEncipherment extendedKeyUsage = serverAuth, clientAuth, codeSigning, emailProtection nsComment = "OpenSSL Generated Certificate" … The OpenSSL x509man pageprovides some commentary: Extensions in certificates are not transferred to certificate requests and vice versa. You are right, of course, we should not copy extensions unconditionally. After my search, I found that many people have raised this question. I find it less painful to use than parsing output of ‘openssl x509’ somewhat stricter in extension parsing compared to openssl; Disadvantages. C = US . While in certain cases some can be interchanged the best practice is to identify how your certificate is encoded and then label it correctly. Transferring extensions from certificates to certificate requests and vice versa. We’ll occasionally send you account related emails. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Why is this problem not fixed yet? Download and setup openssl. It would be nice to support the existing "copy_extensions = copy" feature also in for "openssl x509". name_opt = ca_default # Subject Name options: cert_opt = ca_default # Certificate field options # Extension copying option: use with caution. There is a lot of confusion about what DER, PEM, CRT, and CER are and many have incorrectly said that they are all interchangeable. Sometimes we only need a lightweight tool and don't want to configure openssl.cnf. The syntax of configuration files is described in config(5). x509v3_config - X509 V3 certificate extension configuration format. Copy your default openssl.cnf file to a temporary openssl-san.cnf file ; Edit the openssl-san.cnf file to add addtl. Extensions are defined in the openssl.cfg file. required parameters [req] req_extensions = v3_req [ v3_req ] # Extensions to add to a certificate request basicConstraints = CA:FALSE keyUsage = nonRepudiation, digitalSignature, keyEncipherment subjectAltName = @alt_names [alt_names] DNS.1 = server1.example.com DNS.2 … And BTW, that's great job of finding the complaints. Yes, you can configure the copy_extensions of openssl.cnf and then use "openssl ca" to achieve this effect. @levitte You could copy the extensions one at a time into a STACK_OF (X509_EXTENSION) using the X509 APIs and then pass the duplicates stack to X509_REQ_add_extensions (). # "openssl x509" utility, name here the section containing the # X.509v3 extensions to use: ... # copy_extensions = copy # Extensions to add to a CRL. # openssl x509 extfile params .

From what I understand of openssl (and, reading through the lines, libressl), the copy_extensions = copy in this section should cause the extensions in the CSR to be copied to the output x509 certificate. ST = CA . O = VMware (Dummy Cert) OU = Horizon Workspace (Dummy Cert) CN = hostname … $ openssl req -x509 -sha256 -nodes -newkey rsa:4096 -keyout example.com.key -days 730 -out example.com.pem Creating your own CA and using it to sign the certificates. The curve objects have a unicode name attribute by which they identify themselves.. It can be used to display certificate information, convert certificates to various forms, sign certificate requests like a "mini CA" or edit certificate trust settings. I have a number of SAN entries in my existing cert that need to go across, and even using -extfile with the -x509toreq command doesn't work after I pulled those out. By default, custom extensions are not copied to the certificate. Just as there is a copy_extensions option in openssl.cnf, we should also add the copy_extensions option to the x509 command. Several of the OpenSSL utilities can add extensions to a certificate or certificate request based on the contents of a configuration file. openssl information : DESCRIPTION. The first x509 extension we set is basicConstraints, and we provide it a value of CA:false which, as you might have guessed, says the certificate cannot be used as a CA. C = US . Yes, you can configure the copy_extensions of openssl.cnf and then use "openssl ca" to achieve this effect. Add -copy_extensions option to x509 utility. DESCRIPTION The x509 command is a multi purpose certificate utility. The extension may be created from der data or from an extension oid and value.The oid may be either an OID or an extension name. According to the config file, certificate will be created using some code. to your account. Thus when using "openssl x509" instead, from each CSR, a openssl.config has to be created manually by duplicating the CSR fields before signing, which makes it even more risky and error prone than using the "copy_extensions". However, when libressl is called with the echo form above, I get the following errors: https://stackoverflow.com/questions/33989190/subject-alternative-name-is-not-copied-to-signed-certificate, https://stackoverflow.com/questions/6194236/openssl-version-v3-with-subject-alternative-name, https://stackoverflow.com/questions/30977264/subject-alternative-name-not-present-in-certificate, https://security.stackexchange.com/questions/150078/missing-x509-extensions-with-an-openssl-generated-certificate, https://security.stackexchange.com/questions/158166/how-to-add-altname-from-csr-file-to-crt-file-using-openssl-x509-req, https://security.stackexchange.com/questions/74345/provide-subjectaltname-to-openssl-directly-on-the-command-line, https://www.linuxquestions.org/questions/linux-software-2/get-subjectaltname-into-certificate-my-own-ca-4175479553/, https://forum.ivorde.com/openssl-certificate-authority-ca-how-to-copy-x509-extensions-from-csr-to-signed-pem-t19421.html, https://stackoverflow.com/questions/25900812/certificate-is-not-including-san-names-using-openssl, http://openssl.6102.n7.nabble.com/subjectAltName-removed-from-CSR-when-signing-td26928.html, https://mta.openssl.org/pipermail/openssl-users/2016-January/002759.html.
