2 、Functions by Category 函數分類總結
二、代碼示例
(參考)optee_ctest :https://github.com/OP-TEE/optee_client
1、cipher 對稱加解密
case編號 : xtest_tee_test_4003
ADBG_CASE_DEFINE(regression, 4003, xtest_tee_test_4003,"Test TEE Internal API cipher operations"); 調用次序: ta_crypt_cmd_allocate_operation ta_crypt_cmd_allocate_transient_object ta_crypt_cmd_set_operation_keyta_crypt_cmd_cipher_init ta_crypt_cmd_cipher_update ta_crypt_cmd_cipher_do_finalta_crypt_cmd_free_operation2、Asymmetric 非對稱加解密
case編號 : xtest_tee_test_4006
ADBG_CASE_DEFINE(regression, 4006, xtest_tee_test_4006,"Test TEE Internal API Asymmetric Cipher operations");總結
