Function Documentation

check_signature_with_pki()

check_signature_with_pki_status_t check_signature_with_pki	(	const buffer_t	hash,
		const uint8_t *	expected_key_usage,
		const cx_curve_t *	expected_curve,
		const buffer_t	signature
	)

Checks a signature using the PKI certificate.

This function retrieves the PKI certificate information from the OS, verifies that the key usage and curve match the expected values, and then checks the signature against the provided hash.

Parameters

hash	Buffer containing the hash to verify.
expected_key_usage	Expected key usage value of the loaded certificate or NULL.
expected_curve	Expected elliptic curve of the loaded certificate or NULL.
signature	Buffer containing the signature to verify.

Returns

Status of the signature check (see check_signature_with_pki_status_t).
