What is the password for your test files?

I can't seem to read your unencrypted files using openssl either:

jas at mocca:~$ openssl pkcs8 -inform pem -in test-pem-unencrypt.pkcs8 
Error reading key
19169:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:647:Expecting: ENCRYPTED PRIVATE KEY
jas at mocca:~$ openssl pkcs8 -inform der -in test-der-unencrypt.pkcs8 
Error reading key
19178:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag:tasn_dec.c:1294:

jas at mocca:~$ 

How did you generate the files?
