Server key does not appear to be valid [SOLVED]

[mezcal]

Hi all,

From OpenSSL 1.0 change log:

Make PKCS#8 the default write format for private keys, replacing the traditional format. This form is standardised, more secure and doesn't include an implicit MD5 dependency. [Steve Henson]

However, the pfSense 1.2.3 needs the private key file in the previous, traditional format.

Solution:

openssl rsa -in server.key -out server.key

That`s it.
