Convert a PEM certificate file and a private key to PKCS#12 (.pfx.Note: Add -nocerts to only convert the private key, or add -nokeys to convert only the certificates. p12) including the private key and certificate(s) to PEM openssl pkcs12 -in keyStore.pfx -out keyStore.pem -nodes To make sure that the files are compatible, you can print and compare the values of the SSL Certificate modulus, the Private Key modulus and the CSR modulus. Convert a PEM file to DER openssl x509 -outform der -in certificate.pem -out r From the Linux command line, you can easily check whether an SSL Certificate or a CSR match a Private Key using the OpenSSL utility.der) to PEM openssl x509 -inform der -in certificate.cer -out certificate.pem A PEM file for Apache can, for example, be converted to a PFX (PCKS#12) file for use with Tomcat or IIS. This is sometimes necessary to make certificates or private keys suitable for different types of servers or software. With the commands below files can be converted to another format. openssl s_client -connect Convert certificates using OpenSSL All certificates (also intermediate certificates) should be displayed. openssl x509 -noout -modulus -in certificate.crt | openssl md5 openssl rsa -noout -modulus -in privateKey.key | openssl md5 openssl req -noout -modulus -in CSR.csr | openssl md5 Check the MD5 hash of the public key to check if it is equal to what is in the CSR or private key.Please also use our online SSL Check LINK tool to check the certificate. With error messages like 'the Private Key does not match the Certificate' or 'the Certificate is not Trusted' you can use one of the following commands. p12) openssl pkcs12 -info -in keyStore.p12 Check a certificate openssl x509 -in certificate.crt -text -noout.Check a private key openssl rsa -in privateKey.key -check.Check a CSR openssl req -text -noout -verify -in CSR.csr.Our online Tools LINK can also be used for this purpose. Use the following commands to check the information of a certificate, CSR or private key. Remove a password from a private key openssl rsa -in privateKey.pem -out newPrivateKey.pemĬheck the CSR, Private Key or Certificate using OpenSSL.Generate a self-signed certificate openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout privateKey.key -out certificate.crt.Generate a CSR based on an existing certificate openssl x509 -x509toreq -in MYCRT.crt -out CSR.csr -signkey privateKey.key.Generate a CSR for an existing private key openssl req -out CSR.csr -key privateKey.key -new.Generate a new private key and CSR (Windows) openssl req -out CSR.csr -pubkey -new -keyout privateKey.key -config.Generate a new private key and CSR (Unix) openssl req -utf8 -nodes -sha256 -newkey rsa:2048 -keyout server.key -out server.csr openssl req -out CSR.csr -pubkey -new -keyout privateKey.key.To do this, open up your PowerShell console and run choco install OpenSSL.Lightas shown below.The following commands show how to create CSRs, certificates and private keys, in addition to a few other tasks using OpenSSL. Installing OpenSSL on Windows 10 with PowerShell and ChocolateyĪssuming you have installed Chocolatey using the installation instructions, your first task is to install OpenSSL on Windows 10. PowerShell ISE, Visual Studio Code or any text editor of your choiceĪll screenshots in this guide were taken from Windows 10 build 1909 and PowerShell 7. Chocolatey – A package manager for Windows installed.Windows PowerShell 5.1 (comes with Windows) or PowerShell 7.A Windows system with Local Administrator rights – The tutorial will be using Windows 10.While OpenSSL historically is a Linux OS utility, you can use it with Windows OS as well. OpenSSL is an open-source command-line tool that is commonly used to generate private keys, create CSRs, install our SSL/TLS certificate, and identify. This will display all bundled certs in the file cert-bundle. This allows to chain multiple openssl commands like this: while openssl x509 -noout -text do : done < cert-bundle.pem. In this article, you are going to learn using a hands-on approach. The openssl command (several of its subcommands, including openssl x509) is polite with its data stream: once it read data, it didnt read more than it needed.
