You need a Passphrase to protect your secret key.

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.

You can probably fix the "Illegal byte sequence" warnings by adding charset utf-8 to ~/.gnupg/gpg.conf.
