Function Documentation

alts_unseal_crypter_create()

grpc_status_code alts_unseal_crypter_create	(	gsec_aead_crypter *	gc,
		bool	is_client,
		size_t	overflow_size,
		alts_crypter **	crypter,
		char **	error_details
	)

This method creates an alts_crypter instance used to perform an unseal operation, given a gsec_aead_crypter instance and a flag indicating if the created instance will be used at the client or server side. It takes ownership of gsec_aead_crypter instance.

• gc: a gsec_aead_crypter instance used to perform AEAD decryption.
• is_client: a flag indicating if the alts_crypter instance will be used at the client (is_client = true) or server (is_client = false) side.
• overflow_size: overflow size of counter in bytes.
• crypter: an alts_crypter instance to be returned from the method.
• error_details: a buffer containing an error message if the method does not function correctly. It is legal to pass nullptr into error_details, and otherwise, the parameter should be freed with gpr_free.

On success of creation, the method returns GRPC_STATUS_OK. Otherwise, it returns an error status code along with its details specified in error_details (if error_details is not nullptr).
