Try reading the docs to the applications, rsa, dsa and pkcs8 they give
more info and the source helps.
Mostly it is just b64 encoded DER stuff. OpenSSL understands PKCS#8 and
can generate or convert to that format in both encrypted and unencrypted
forms.
The only undocumented form is the 'traditional' PEM encoded encrypted
form which is a weird PKCS#5 variant with IV and salt stuff in the
header but the various utilities and functions can convert that.
