Question

Can any one able to tell me how to encrypt and decrypt a xml file using openssl. I can able to create privatekey using the Linux command

openssl genrsa -out private.pem 1024 

And got my private key as private.pem. Created public key using

openssl rsa -in private.pem -out public.pem -outform PEM -pubout

got my public key as public.pem

Now what I want is I want to encrypt the XML file using this public key and again want to decrypt using my private key.

Answer 1

Try:

$ openssl rsautl -encrypt -inkey public.pem -pubin -in file.xml -out file.xml.encrypted
