10. One Asymmetric Key and the Textual Encoding of PKCS #8 Private Key Info​

Unencrypted PKCS #8 Private Key Information Syntax structures (PrivateKeyInfo), renamed to Asymmetric Key Packages (OneAsymmetricKey), are encoded using the "PRIVATE KEY" label. The encoded data MUST be a BER (DER preferred; see Appendix B) encoded ASN.1 PrivateKeyInfo structure as described in PKCS #8 [RFC5208], or a OneAsymmetricKey structure as described in [RFC5958]. The two are semantically identical and can be distinguished by version number.
