思考:
????下面 三個(gè)宏分別是什么含義？
????????? TEE_ALG_RSAES_PKCS1_V1_5
????????? TEE_ALG_RSASSA_PKCS1_V1_5_SHA256
????????? TEE_ALG_RSAES_PKCS1_OAEP_MGF1_SHA256

例如在下面的一個(gè)示例中，如果是加解密則使用的TEE_ALG_RSAES_PKCS1_V1_5，如果是簽名驗(yàn)簽則使用的是TEE_ALG_RSASSA_PKCS1_V1_5_SHA256

switch (mode){case TEE_MODE_ENCRYPT:case TEE_MODE_DECRYPT:alg = TEE_ALG_RSAES_PKCS1_V1_5;break;case TEE_MODE_SIGN:case TEE_MODE_VERIFY:alg = TEE_ALG_RSASSA_PKCS1_V1_5_SHA256;break;}

上述的ES、SSA分別是什么含義呢？ OAEP 、MGF1、PSS分別又是什么含義呢？

RSAES : RSA Encryption Scheme <參考這里>
RSASSA : RSA Signature Scheme with Appendix <參考這里>
OAEP : Optimal Asymmetric Encryption Padding — 加解密使用的padding
PSS : probabilistic signature scheme — 簽名驗(yàn)簽使用的
MGF : mask generation function
