brp_Pki_StoreX509RootCert()

brp_errcode brp_Pki_StoreX509RootCert	(	brp_protocol	protocol,
		unsigned	SecLevel,
		brp_buf	Cert,
		size_t	Cert_len
	)

Every security level that should be usable with the PKI must be provided with a root certificate. The certificate chain provided in the Pki.PfsAuthHostCert command will be verified against this root certificate.

The root certificates must comply with the following limitations:

• Certificates have to be X.509 v3 certificates.
• Only ECC P-256 and SHA256 are allowed as signing algorithms.
• The length of the tags containing the Issuer Unique Identifier and the Subject Unique Identifier must not exceed 128 Bytes.
• The only allowed extension is basicConstraints (indicating the certificate is a CA certificate)
• The validity period always has to be from "Jan 1 00:00:00 2000 GMT" to "Jan 19 02:14:07 2038 GMT".

A sample certificate matching all these limitations is the following:

Furthermore, the access conditions mask of the security llevel running the Pki.StoreX509RootCert command has to allow setting the corresponding key (SEC_SETKEY1, SEC_SETKEY2 or SEC_SETKEY3 bit of the access condition mask must be set).

This command needs a long timeout, since the ECC operations may take up to 15 seconds.

[in]	SecLevel	Security level (1-3), for which the root certificate should be stored.
