OpenSSL

As explained in Building Web APIs with ASP.NET Core

OpenSSL is an open-source toolkit and command-line tool for cryptography, certificates, and related security files.

OpenSSL is an open-source command-line toolkit for cryptography, certificates, and related security files. In a Windows deployment, it converts PEM and KEY certificate files into a PFX file that IIS can import. section 12.3.5

Use OpenSSL for the IIS certificate-import workflow:

Install Win64 OpenSSL v3.0.5 Light, whose basic features are sufficient for this conversion. section 12.3.5
Open a command prompt, move to the folder containing the PEM and KEY files, and run the PKCS#12 export command. section 12.3.5
Enter and remember an export password, then use the generated PFX file in IIS and delete the unnecessary PEM and KEY files locally. section 12.3.5

Convert PEM and KEY files to PFX

"C:\Program Files\OpenSSL-Win64\bin\openssl.exe" pkcs12 -export -out mybglist_origin.pfx -in mybglist_origin.pem -inkey mybglist_origin.key section 12.3.5

"C:\Program Files\OpenSSL-Win64\bin\openssl.exe" pkcs12 
   -export -out mybglist_origin.pfx 
   -in mybglist_origin.pem -inkey mybglist_origin.key

Open the supplied listing to inspect the complete Windows command used for certificate conversion. section 12.3.5

self-signed certificateproduces · A self-signed certificate is a digital certificate whose signature is created by the same entity and key identified by the certificate rather than by a certificate authority.
TLSimplements · Transport Layer Security (TLS) is a cryptographic protocol that protects network communications through confidentiality, integrity, and authentication of communicating endpoints.
certificateuses · A digital certificate is a digitally signed credential that binds an identity to a public key and supports authentication or secure communication.
