Those examples aren't equivalent. For the PKCS#8 blob you are first
using openssl to convert from an encrypted PKCS#8 PEM to unencrypted
DER, presumably because you haven't added decryption support (or base64
decode) to keyctl yet.
For the TPM example though, you are also showing the *generation* of
the key, and importing it into the TPM. And then I'm confused by the
'openssl asn1parse' line there... what is that actually doing? If I run
it on a '-----BEGIN TSS KEY BLOB-----' file I have lying around, I get
no output at all.
