And BTW, that's great job of finding the complaints. Including v3 extensions via copy_extensions in the config file should also produce an x509v3 certificate. Documentation for openSSL tool is available here. Already on GitHub? In fact, you can also add extensions to "openssl x509" by using the -extfile option. We’ll occasionally send you account related emails. 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 would be nice to support the existing "copy_extensions = copy" feature also in for "openssl x509". 3. Download and setup openssl. The syntax of configuration files is described in config(5). 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 oid may be either an OID or an extension name. Basic signing might be neccessary when the "openssl ca" magic is too much and cannot be turned off in certain usecases. The text was updated successfully, but these errors were encountered: It is not really a bug, it is a security concern. 161 1 1 gold badge 1 1 silver badge 5 5 bronze badges. The job of a CA is to look at the request and verify all extensions before putting them into the cert. I need to see them and validate them with the owner of the certificate. # openssl x509 extfile params . extensions = extend [req] # openssl req params . $ 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. Add -copy_extensions option to x509 utility. Have a question about this project? # crlnumber must also be commented out to leave a V1 CRL. However, when libressl is called with the echo form above, I get the following errors: There isn't a function to get all extensions. If critical is true the extension is marked critical. 1. 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. Copy and paste the following OpenSSL commands into the configuration file. You signed in with another tab or window. It would be nice to support the existing "copy_extensions = copy" feature also in for "openssl x509". Extensions in certificates are not transferred to certificate requests and vice versa. I find it less painful to use than parsing output of ‘openssl x509’ somewhat stricter in extension parsing compared to openssl; Disadvantages. X509 V3 certificate extension configuration format . asked Apr 21 '17 at 17:00. dizel3d dizel3d. Create a configuration file using the vi openssl_ext.conf command. 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. Use a text editor to edit the openssl_local.cfg file that was created by the above copy command. This has just hit me as well. In fact, you can also add extensions to "openssl x509" by using the -extfile option. It also offers many scripting features to process plain text and serialized files, or manage system tasks. Elliptic curves¶ OpenSSL.crypto.get_elliptic_curves ¶ Return a set of objects representing the elliptic curves supported in the OpenSSL build in use. To make openssl copy the requested extensions to the certificate one has to specify copy_extensions = copy for the signing. 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. Copy your default openssl.cnf file to a temporary openssl-san.cnf file ; Edit the openssl-san.cnf file to add addtl. 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. While already supported with "openssl ca", basic signing does not support the "copy_extension" mode. It's very disappointing. When i set the same text as i found in other extension, i don't have the same value in the asn1_string : STACK_OF (X509_EXTENSION)* sk_ext = cert->cert_info->extensions; X509_EXTENSION *ex2 =sk_X509_EXTENSION_value(sk_ext, 1); cout << "B :"<value->data) << endl; I get : A :43413A54525545 B :30030101FF But this value must be the same (value = "CA:TRUE", A is the … The first thing we have to understand is what each type of file extension is. Why does the x509 command not copy extension in certificate request? OpenSSL::X509::Extension.new(oid, value, critical) Creates an X509 extension. Why does the x509 command not copy extension in certificate request. You signed in with another tab or window. Next we set subjectKeyIdentifier to hash - this means the method for finding the SKI is to hash the public key. I think it is different from "openssl ca". 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". O = VMware (Dummy Cert) OU = Horizon Workspace (Dummy Cert) CN = hostname … If critical is true the extension … Transferring extensions from certificates to certificate requests and vice versa. 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 … (It would be even more nice, if it would allow "... = copy:subjectAltName", but that is another story ...). 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 … * this file except in compliance with the License. The file openssl.cnf that comes with the installation contains configuration information used by the openssl commands. privacy statement. Download and unzip openSSL tool in an empty directory. By default, custom extensions are not copied to the certificate. C = US . Sometimes we only need a lightweight tool and don't want to configure openssl.cnf. The extension may be created from der data or from an extension oid and value. 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. 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 (). Have a question about this project? These examples are extracted from open source projects. The curve objects have a unicode name attribute by which they identify themselves.. Already on GitHub? Ruby is an interpreted object-oriented programming language often used for web development. BUGS 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". Copy and paste the following OpenSSL commands into the configuration file. Since there are a large number … It is unclear that -extensions (or x509_extensions) must be used in order to create an x509v3 certificate. to your account. In vanilla installations this means that this line has to be added to the section default_CA in openssl.cnf. WIP : Added first draft of common component for handling certificates and related secrets. While in certain cases some can be interchanged the best practice is to identify how your certificate is encoded and then label it correctly. You can obtain a copy @@ -240,8 +240,9 @@ static int trust_1oid(X509_TRUST *trust, X509 *x, int flags) 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" … 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. Delete the # if it is there. Perhaps one way around this is to add a couple of flags to the ca command. You are right, of course, we should not copy extensions unconditionally. 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. x509v3_config - X509 V3 certificate extension configuration format. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. to your account. # "openssl x509" utility, name here the section containing the # X.509v3 extensions to use: ... # copy_extensions = copy # Extensions to add to a CRL. Sign in Why is this problem not fixed yet? After my search, I found that many people have raised this question. "openssl x509" is a more lightweight certificate operation tool. Typically the application will contain an option to point to an extension section. OpenSSL itself does not copy anyextensions from PKCS #10 requests to X.509 certificates; all extensions for certificates must be explicitly declared. To add extension to the certificate, first we need to modify this config file. prompt = no . Rewrite comment about OpenSSL extension handling, The x509 and req apps should copy X.509 extensions when converting formats, Fail-exit if there are unknown extensions. # openssl x509 extfile params . We’ll occasionally send you account related emails. Just as there is a copy_extensions option in openssl.cnf, we should also add the copy_extensions option to the x509 command. 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. Create a configuration file using the vi openssl_ext.conf command. privacy statement. Successfully merging a pull request may close this issue. 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. 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. x509_extensions = usr_cert # The extentions to add to the cert # Comment out the following two lines for the "traditional" # (and highly broken) format. 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. Several of the OpenSSL utilities can add extensions to a certificate or certificate request based on the contents of a configuration file. By clicking “Sign up for GitHub”, you agree to our terms of service and 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. prompt = no . distinguished_name = dn-param [dn-param] # DN fields . DESCRIPTION The x509 command is a multi purpose certificate utility. Please give me a reason. ST = CA . Note: Netscape communicator chokes on V2 CRLs # so this is commented out by default to leave a V1 CRL. 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. Extensions are defined in the openssl.cfg file. openssl information : DESCRIPTION. openssl req -new -x509 -sha256 -days 3650 -config ssl.conf -key ssl.key -out ssl.crt openssl. Sign in distinguished_name = dn-param [dn-param] # DN fields . X509 V3 extensions options in the configuration file are: 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. Normal certificates should not have the authorisation to sign other certificates. By clicking “Sign up for GitHub”, you agree to our terms of service and O = VMware (Dummy Cert) OU = Horizon Workspace (Dummy Cert) CN = hostname … Yes, you can configure the copy_extensions of openssl.cnf and then use "openssl ca" to achieve this effect. This should be done using special certificates known as Certificate Authorities (CA). The following are 30 code examples for showing how to use OpenSSL.crypto.X509Extension (). DESCRIPTION. C = US . extensions = extend [req] # openssl req params . According to the config file, certificate will be created using some code. Support "copy_extensions" also with x509 CSR signing.
