How to change a .p12 file to .key file

问题

I have a .p12 file, I can also transfer it to a .pem file, but how to transfer it as a .key file?

回答1:

openssl pkcs12 -in out.p12 -nodes -out private.key -nocerts

openssl will ask you for a password, then store the unencrypted private key into the file private.key
