ios - Multipeer Connectivity 框架中使用的加密？

Question

嘿，我在 ios 中为聊天应用程序使用多对等连接框架。此框架是否支持任何加密。我想了解此框架中使用的加密，如 AES 或 RSA 加密系统？我的发现或研究:

是的，MCSession.h类中有一个加密选项

 // Encryption preference.
typedef NS_ENUM (NSInteger, MCEncryptionPreference) {
MCEncryptionOptional = 0,                   // session preferred encryption but will accept unencrypted connections
MCEncryptionRequired = 1,                   // session requires encryption
MCEncryptionNone = 2,                       // session should not be encrypted
} NS_ENUM_AVAILABLE (10_10, 7_0);

调用这个方法:

- (instancetype)initWithPeer:(MCPeerID *)myPeerID
        securityIdentity:(nullable NSArray *)identity
    encryptionPreference:(MCEncryptionPreference)encryptionPreference NS_DESIGNATED_INITIALIZER;
