器件型号：CC2745R10-Q1工具/软件：
您好：
我的环境如下：
板：CC2745R10-Q1
调试器：XDS110
SDK：SimpleLink Lowpower f3 ver.9.10.00.83
IDE：IAR Embedded Workbench for ARM 9.60.3.7274
由于密钥库中可存储的密钥数量有限、
相同的密钥即可实现多种功能。
这是可能的吗？ 如果是、请告诉我如何操作。
在下面的测试代码中、
导入密钥时未指定算法：
PSA_set_key_algorithm (&attributes、PSA_ALG_none)；
我只想在使用时指定算法、
PSA_RAW_KEY_Agreement (PSA_ALG_ECDH、KEY_ID、‥
PSA_SIGN_HASH (KEY_ID、PSA_ALG_ECDSA (PSA_ALG_SHA_256)、‥μ s
这不起作用 (PSA_IMPORT_KEY 返回的错误代码–135)。
