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 (). While already supported with "openssl ca", basic signing does not support the "copy_extension" mode. The text was updated successfully, but these errors were encountered: It is not really a bug, it is a security concern. Copy your default openssl.cnf file to a temporary openssl-san.cnf file ; Edit the openssl-san.cnf file to add addtl. (It would be even more nice, if it would allow "... = copy:subjectAltName", but that is another story ...). # openssl x509 extfile params . Sometimes we only need a lightweight tool and don't want to configure openssl.cnf. OpenSSL "x509 -fingerprint" - Print Certificate Fingerprint How to print out MD5 and SHA-1 fingerprints of a certificate using OpenSSL "x509" command? $ 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. Copy and paste the following OpenSSL commands into the configuration file. Yes, you can configure the copy_extensions of openssl.cnf and then use "openssl ca" to achieve this effect. Why is this problem not fixed yet? to your account. Already on GitHub? Extensions in certificates are not transferred to certificate requests and vice versa. While in certain cases some can be interchanged the best practice is to identify how your certificate is encoded and then label it correctly. 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. 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. Normal certificates should not have the authorisation to sign other certificates. If critical is true the extension is marked critical. * this file except in compliance with the License. X509 V3 certificate extension configuration format . 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. Of course, I am not the first person to encounter this problem. 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. privacy statement. 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 … share | improve this question | follow | edited Apr 23 '17 at 18:20. dizel3d. By clicking “Sign up for GitHub”, you agree to our terms of service and https://www.openssl.org/docs/man1.1.1/man1/x509.html. The oid may be either an OID or an extension name. There is a lot of confusion about what DER, PEM, CRT, and CER are and many have incorrectly said that they are all interchangeable. Have a question about this project? In fact, you can also add extensions to "openssl x509" by using the -extfile option. Note: Netscape communicator chokes on V2 CRLs # so this is commented out by default to leave a V1 CRL. 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. Copy and paste the following OpenSSL commands into the configuration file. Please give me a reason. The text was updated successfully, but these errors were encountered: Successfully merging a pull request may close this issue. 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. 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. Extensions are defined in the openssl.cfg file. 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: Creates an X509 extension.. BUGS According to the config file, certificate will be created using some code. Create a configuration file using the vi openssl_ext.conf command. Create a configuration file using the vi openssl_ext.conf command. There isn't a function to get all extensions. In vanilla installations this means that this line has to be added to the section default_CA in openssl.cnf. Ruby is an interpreted object-oriented programming language often used for web development. @levitte to your account. Basic signing might be neccessary when the "openssl ca" magic is too much and cannot be turned off in certain usecases. I think it is different from "openssl ca". The curve objects have a unicode name attribute by which they identify themselves.. And BTW, that's great job of finding the complaints. The following are 30 code examples for showing how to use OpenSSL.crypto.X509Extension (). distinguished_name = dn-param [dn-param] # DN fields . distinguished_name = dn-param [dn-param] # DN fields . openssl req -new -x509 -sha256 -days 3650 -config ssl.conf -key ssl.key -out ssl.crt openssl. It also offers many scripting features to process plain text and serialized files, or manage system tasks. "openssl x509" is a more lightweight certificate operation tool. The syntax of configuration files is described in config(5). Sign up for a free GitHub account to open an issue and contact its maintainers and the community. X509 V3 extensions options in the configuration file are: Typically the application will contain an option to point to an extension section. ST = CA . 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. Since there are a large number … Sign in Just as there is a copy_extensions option in openssl.cnf, we should also add the copy_extensions option to the x509 command. I need to see them and validate them with the owner of the certificate. prompt = no . Delete the # if it is there. To make openssl copy the requested extensions to the certificate one has to specify copy_extensions = copy for the signing. It would be nice to support the existing "copy_extensions = copy" feature also in for "openssl x509". Download and setup openssl. Why does the x509 command not copy extension in certificate request. 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 … Transferring extensions from certificates to certificate requests and vice versa. The file openssl.cnf that comes with the installation contains configuration information used by the openssl commands. The job of a CA is to look at the request and verify all extensions before putting them into the cert. We’ll occasionally send you account related emails. privacy statement. We’ll occasionally send you account related emails. C = US . extensions = extend [req] # openssl req params . 1. # crlnumber must also be commented out to leave a V1 CRL. C = US . 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. The extension may be created from der data or from an extension oid and value. It's very disappointing. # openssl x509 extfile params . This should be done using special certificates known as Certificate Authorities (CA). You signed in with another tab or window. X509 Certificate can be generated using OpenSSL. Including v3 extensions via copy_extensions in the config file should also produce an x509v3 certificate. extensions = extend [req] # openssl req params . To add extension to the certificate, first we need to modify this config file. ST = CA . 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. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Download and unzip openSSL tool in an empty directory. The problem encountered by so many people is only because of a small bug here. Have a question about this project? 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" … This has just hit me as well. You can obtain a copy @@ -240,8 +240,9 @@ static int trust_1oid(X509_TRUST *trust, X509 *x, int flags) Documentation for openSSL tool is available here. 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. # "openssl x509" utility, name here the section containing the # X.509v3 extensions to use: ... # copy_extensions = copy # Extensions to add to a CRL. I find it less painful to use than parsing output of ‘openssl x509’ somewhat stricter in extension parsing compared to openssl; Disadvantages. x509v3_config - X509 V3 certificate extension configuration format. The first thing we have to understand is what each type of file extension is. By default, custom extensions are not copied to the certificate. 161 1 1 gold badge 1 1 silver badge 5 5 bronze badges. OpenSSL itself does not copy anyextensions from PKCS #10 requests to X.509 certificates; all extensions for certificates must be explicitly declared. After my search, I found that many people have raised this question. DESCRIPTION The x509 command is a multi purpose certificate utility. DESCRIPTION. Yes, you can configure the copy_extensions of openssl.cnf and then use "openssl ca" to achieve this effect. Already on GitHub? By clicking “Sign up for GitHub”, you agree to our terms of service and It would be nice to support the existing "copy_extensions = copy" feature also in for "openssl x509". Support "copy_extensions" also with x509 CSR signing. O = VMware (Dummy Cert) OU = Horizon Workspace (Dummy Cert) CN = hostname … Why does the x509 command not copy extension in certificate request? prompt = no . You are right, of course, we should not copy extensions unconditionally. 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. Next we set subjectKeyIdentifier to hash - this means the method for finding the SKI is to hash the public key. 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 :"<
