The first question that comes to my mind is: where did you stumble across it? Unlikely that you made it, otherwise you'd know what that means. Did you find it on educational website? Also unlikely, because it'd explain you what that means. So, my conclusion is that someone sold it to you?
There's no standard I know with 98 characters long private keys.
A coworker asked me If there is a better way to find someone on Google (She is a secretary. sometimes our boss asks her to contact someone in particular) and Ive decided to teach Google Dorking to her. While I was teaching her, Ive stumbled across a file that cointained some infos (and this private Key). I was curious because I never saw a Private Key that long and searching about It, I found nothing. Ive decided to post It here because maybe this could be a really strong encoding metod there is worth to use.
I didn't tried the finderouter, but Ive found in the Apple website a cryptography called "SECG" that has 97 characters. Do you know something about It?
The first thing you need to determine is the encoding. You can't determine if or how the data is encrypted before you determine the encoding.
I miswrited It, srry. English isn't my Native language and I may mess up with some words. Anyway, "SECG" is a encoding method that produces 97 characters long private keys.
