priv pub key encoding - Githubissues

Hey, this looks like unicode (utf8?), do you have any pointers on how I can generate this?

    public_key: {
        der: "\x30\x59\x30\x13\x06\x07\x2a\x86\x48\xce\x3d\x02\x01\x06\x08\x2a\x86\x48\xce\x3d\x03\x01\x07\x03\x42\x00\x04\x07\xf8\x51\xaf\xaa\x8c\x56\x83\x90\x31\xb7\x80\xe3\xd6\x1a\xf7\x2f\x36\x06\x71\xec\xdd\x3b\xbe\x7e\x36\x6f\x0d\x1c\x1c\x60\x0b\x7f\xf5\x9f\xff\xe5\x24\x49\x34\x56\xf2\x4b\x10\x5f\xbf\x08\x1f\xf9\x0e\xcf\x35\xb5\x8a\x8a\x8b\x30\x0a\x54\xb7\xbf\x1d\x4d\xb9"
    }

            der: "\x30\x81\x87\x02\x01\x00\x30\x13\x06\x07\x2a\x86\x48\xce\x3d\x02\x01\x06\x08\x2a\x86\x48\xce\x3d\x03\x01\x07\x04\x6d\x30\x6b\x02\x01\x01\x04\x20\x84\x33\x84\xfa\x1c\x30\xf8\x12\xf3\xe7\x38\x8f\x52\xe0\xd9\xd3\x5a\x05\x20\x6f\xfa\xe7\xe9\xc7\xea\x23\xc5\x32\x01\x79\xd4\x85\xa1\x44\x03\x42\x00\x04\x07\xf8\x51\xaf\xaa\x8c\x56\x83\x90\x31\xb7\x80\xe3\xd6\x1a\xf7\x2f\x36\x06\x71\xec\xdd\x3b\xbe\x7e\x36\x6f\x0d\x1c\x1c\x60\x0b\x7f\xf5\x9f\xff\xe5\x24\x49\x34\x56\xf2\x4b\x10\x5f\xbf\x08\x1f\xf9\x0e\xcf\x35\xb5\x8a\x8a\x8b\x30\x0a\x54\xb7\xbf\x1d\x4d\xb9"

Here's how we do it. I'll take recommendations for improvements too. I hope this helps!
