Digital Certificates Code Signing Certificate

Hi Folks,

We had received signed certificate in .PFX format good to install this on windows machine. To import this certificate in to my application and subsequently regenerate jar files i need .crt format.

Can anyone guide me to convert .PFX certificate to .CRT format.

Thanks,

Hi rparthas,

The fast route (only use the public files to convert, never upload you private-key to anyone):

Or a version with command-line tools:

I tried the command :

openssl pkcs12 -in Code-Sign.pfx -clcerts -nokeys -out adkeystore.crt

Later ran the import command as :

hostname-username$ adjkey -import -file adkeystore.crt -trustcacerts
