oe_result_t oe_get_seal_key_by_policy ( oe_seal_policy_t  seal_policy, uint8_t *  key_buffer, size_t *  key_buffer_size, uint8_t *  key_info, size_t *  key_info_size  ) Get a symmetric encryption key derived from the specified policy and coupled to the enclave platform. Parameters seal_policy The policy for the identity properties used to derive the seal key. key_buffer The buffer to write the resulting seal key to. key_buffer_size The size of the key_buffer buffer. If this is too small, this function sets it to the required size and returns OE_BUFFER_TOO_SMALL. When this function success, the number of bytes written to key_buffer is set to it. key_info Optional buffer for the enclave-specific key information which can be used to retrieve the same key later, on a newer security version. key_info_size The size of the key_info buffer. If this is too small, this function sets it to the required size and returns OE_BUFFER_TOO_SMALL. When this function success, the number of bytes written to key_info is set to it. Return values OE_OK The seal key was successfully requested. OE_INVALID_PARAMETER At least one parameter is invalid. OE_BUFFER_TOO_SMALL The key_buffer or key_info buffer is too small. OE_UNEXPECTED An unexpected error happened.
