11 - Openssl For Windows
openssl req -new -key private.key -out request.csr Interactive prompts for distinguished name. Use -subj for non-interactive scripting:
openssl genpkey -algorithm RSA -out private.key -pkeyopt rsa_keygen_bits:2048 Alternative legacy: openssl genrsa -out private.key 2048 openssl for windows 11
Import-PfxCertificate -FilePath C:\path\to\bundle.pfx -CertStoreLocation Cert:\LocalMachine\My -Password (ConvertTo-SecureString "YourPassword" -AsPlainText -Force) For DER (.cer) as trusted root: openssl req -new -key private
openssl s_client -starttls smtp -connect mail.example.com:587 4.5.1 Compute SHA-256 Hash openssl for windows 11
# In WSL terminal sudo apt update sudo apt install openssl -y openssl version Access Windows files: openssl req -new -key /mnt/c/Users/YourName/key.pem ...
openssl verify -CAfile root.crt -untrusted intermediate.crt server.crt Windows 11 native tools (certlm.msc, certmgr.msc) prefer PKCS#12 (.pfx/.p12) or DER (.cer). OpenSSL bridges the gap.
