 PKCS #8 Format
 ~~~~~~~~~~~~~~
 
-PKCS #8 is a serialization format originally standardized by RSA and
-currently maintained by the IETF in :rfc:`5208`. It supports password based
-encryption and additional key metadata attributes.

 Traditional OpenSSL Format
 ~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-The "traditional" PKCS #1 based serialization format used by OpenSSL.
-It supports password based symmetric key encryption. Commonly found in
-OpenSSL based TLS applications. It is usually found in PEM format with a
-header that mentions the type of the serialized key. e.g.
-``-----BEGIN RSA PRIVATE KEY-----``.
