PKCS #8: Private-Key Information Syntax Standard
This standard describes syntax for private-key information, including a private key for some public-key algorithm and a set of attributes. The standard also describes syntax for encrypted private keys. The intention of including a set of attributes is to provide a simple way for a user to establish trust in information such as a distinguished name or a top-level certification authority's public key.
This module is provided as a service to implementors, but that in case there is any discrepancy between it and the v1.2 doc itself, the doc takes presedence.
