+.Sh DESCRIPTION
+.Fn d2i_PKCS8_PRIV_KEY_INFO
+and
+.Fn i2d_PKCS8_PRIV_KEY_INFO
+decode and encode an ASN.1
+.Vt PrivateKeyInfo
+structure defined in RFC 5208 section 5.
+.Pp
+.Fn d2i_PKCS8_PRIV_KEY_INFO_bio ,
+.Fn i2d_PKCS8_PRIV_KEY_INFO_bio ,
+.Fn d2i_PKCS8_PRIV_KEY_INFO_fp ,
+and
+.Fn i2d_PKCS8_PRIV_KEY_INFO_fp
+are similar except that they decode or encode using a
+.Vt BIO
+or
+.Vt FILE
+pointer.
+.Pp
+For details about the semantics, examples, caveats, and bugs, see
+.Xr ASN1_item_d2i 3 .
+.Pp
+These functions all use unencrypted DER format.
+To store private keys in encrypted form, consider
+.Xr d2i_PKCS8PrivateKey_bio 3
+or
+.Xr PEM_write_PKCS8PrivateKey 3 .
+.Sh RETURN VALUES
+.Fn d2i_PKCS8_PRIV_KEY_INFO ,
+.Fn d2i_PKCS8_PRIV_KEY_INFO_bio ,
+and
+.Fn d2i_PKCS8_PRIV_KEY_INFO_fp
+return a
+.Vt PKCS8_PRIV_KEY_INFO
+object or
+.Dv NULL
+if an error occurs.
+.Pp
+.Fn i2d_PKCS8_PRIV_KEY_INFO
+returns the number of bytes successfully encoded or a negative value
+if an error occurs.
+.Pp
+.Fn i2d_PKCS8_PRIV_KEY_INFO_bio
+and
+.Fn i2d_PKCS8_PRIV_KEY_INFO_fp
+return 1 for success or 0 if an error occurs.
