Not sure if this is needed but here are some additional commands I am using to generate the rest of the Intermediate CA:Ĭreating Intermediate CA private key: openssl genrsa -aes256 -out private/ 4096Ĭreating Intermediate CSR: openssl req -config intermediateca. How can I get error output for this issue?.Openssl responds with: Enter pass phrase for C:/Certificates/RootCA/private/:Īnd when I enter the password, nothing happens after that.Ī good answer to this question would have two parts: Generate the private key using a strong encryption algorithm such as 4096-bit AES256. out C:/Certificates/IntermediateCA/public/ Create an OpenSSL configuration file called caintermediate. in C:/Certificates/IntermediateCA/csr/ ^ The command it is failing on is: openssl ca -config rootca.cnf -extensions v3_intermediate_ca ^ No error message and no certificates are made. Using OpenSSL on Windows 10 to Generate a CSR & Private Key Before you can create an SSL certificate, you must generate a certifiate-signing request (CSR). Invalid certificate policies in leaf certificates are silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. This guide is not meant to be comprehensive. Security Advisory Description CVE-2023-0465 Applications that use a non-default option when verifying certificates may be vulnerable to an attack from a malicious CA to circumvent certain checks. We designed this quick reference guide to help you understand the most common OpenSSL commands and how to use them. We can create a self-signed certificate with just a private key: openssl req -key domain.key -new -x509 -days 365 -out domain.crt. OpenSSL is an open-source command line tool that is commonly used to generate private keys, create CSRs, install your SSL/TLS certificate, and identify certificate information. ![]() The -days option specifies the number of days that the certificate will be valid. I am trying to use a Root CA to sign a CSR for an Intermediate certificate and OpenSSL asks for my password and then after that nothing happens. openssl x509 -signkey domain.key -in domain.csr -req -days 365 -out domain.crt.
