近期公司項目需要用到Rsa加解密,特此編寫了此demo

};
//類方法,初始化設置公私鑰Tag
+ (instancetype)sharedInstancePrivateTag:(NSData*)privateTag publicTag:(NSData*)publicTag;
//臨時創建后臨時更改公私鑰tag
- (void) setPrivateTag:(NSData*)privateTag publicTag:(NSData*)publicTag;
//create Rsa generateKeys publicKey and privateKey
- (RSA_SATAUS)createRSA_generate_keys;
//encrypt someDataString use privateKey
- (RSA_SATAUS)encryptBeforeEncryptDataIn:(NSData*)encryptDataIn EncryptDataOut:(NSData**)encryptDataOut;
//decode SomeEncryptData use publicKey
- (RSA_SATAUS)decodeBeforeEncryptDataIn:(NSData*)encryptDataIn DecodeRncryptDataOut:(NSData**)decodeEncryptDataOut;
//del public and private keys Use KyesTag;
- (RSA_SATAUS)deleteRsaKeys;

此demo 對類進行封裝,封裝系統加解密方法,實現數據的加解密.
公鑰私鑰存儲在keychain中,方法調用簡單詳情參照demo來完成.
如有錯誤請批評指出.
