Can create RSA key pairs of bit lenght 512,1024, 2048 (2048 is added in version 1.2). Graphical interface OpenSSL interface Generate security certificate OpenSSL Interface GUI Security. For a 32-bit system, replace OpenSSL-Win64 with OpenSSL-Win32. Generate Certificates with OpenSSL on Windows Server 2019. You are now ready to use OpenSSL on Windows Server 2019 to generate certificates. Start by exporting OPENSSLCONF. Set OPENSSLCONF=C: OpenSSL-Win64 bin openssl.cfg. For a 32-bit system, replace OpenSSL-Win64 with OpenSSL. If you're not sure how, you can always put openssl-wizard in the same folder as openssl.exe. If you don't need to run openssl, you can still click the copy button to copy the openssl command to the clipboard. Sections RSA Key. Generate an RSA key of specified length,.


An RSA key is a private key based on RSA algorithm, used for authentication and an symmetric key exchange during establishment of an SSL/TLS session.

The RSA private key in PEM format (the most common format for X.509 certificates, CSRs and cryptographic keys) can be generated from the command line using the openssl genpkey utility.

Cool Tip: Check whether an SSL Certificate or a CSR match a Private Key using the OpenSSL utility from the command line! Read more →
