Well I ran the command openssl asn1parse -in ca.key I got a bunch of numbers, a hex dump, and something that says 'rsaEncryption' but I don't see anything that looks like ASN.1, DER or PEM. You were right that I want the output to stay the same as the original. My key is human readable. It does have MII at the start but it also has ----Begin Private Key---- at the beginning. Any more steps to follow to find out what type of key this is? > Date: Tue, 6 Jan 2015 00:23:35 -0500 > From: noloader at gmail.com > To: openssl-users at openssl.org > Subject: Re: [openssl-users] Need help encrypting my ca.key > > On Tue, Jan 6, 2015 at 12:04 AM, jack seth <bird_112 at hotmail.com> wrote: > > Thanks for the response.
