二、代码示例

(参考)optee_ctest :https://github.com/OP-TEE/optee_client

1、cipher 对称加解密

case编号 : xtest_tee_test_4003

ADBG_CASE_DEFINE(regression, 4003, xtest_tee_test_4003,
		"Test TEE Internal API cipher operations");
调用次序:
ta_crypt_cmd_allocate_operation
ta_crypt_cmd_allocate_transient_object
ta_crypt_cmd_set_operation_key

ta_crypt_cmd_cipher_init
ta_crypt_cmd_cipher_update
ta_crypt_cmd_cipher_do_final

ta_crypt_cmd_free_operation

2、Asymmetric 非对称加解密

case编号 : xtest_tee_test_4006

ADBG_CASE_DEFINE(regression, 4006, xtest_tee_test_4006,
		"Test TEE Internal API Asymmetric Cipher operations");
