smStatus_t Se05x_API_RSAVerify(pSe05xSession_t session_ctx, uint32_t objectID, SE05x_RSASignatureAlgo_t rsaSigningAlgo, const uint8_t *inputData, size_t inputDataLen, const uint8_t *signature, size_t signatureLen, SE05x_Result_t *presult)

Se05x_API_RSAVerify

The RSAVerify command verifies the given signature and returns the result.

The key cannot be passed externally to the command directly. In case users want to use the command to verify signatures using different public keys or the public key value regularly changes, the user should create a transient key object to which the key value is written and then the identifier of that transient secure object can be used by this RSAVerify command.
