Objective-C实现Diffie—Hellman密钥交换

Diffie-Hellman密钥交换是一种安全的密钥交换协议，允许两方在不安全的信道上共同生成一个共享的秘密密钥。下面是一个用Objective-C实现Diffie-Hellman密钥交换的示例。

完整源码示例
我们将创建一个名为DiffieHellman的类来实现Diffie-Hellman密钥交换。

创建DiffieHellman类

DiffieHellman.h


#import <Foundation/Foundation.h>

@interface DiffieHellman : NSObject

@property (nonatomic, strong) NSNumber *privateKey;
@property (nonatomic, strong) NSNumber *publicKey;
@property (nonatomic, strong) NSNumber *sharedSecret;

- (instancetype)initWithPrivateKey:(NSNumber *)privateKey base:(NSNumber *)base prime:(NSNumber *)prime;
- (NSNumber *)generatePublicKey;
- (NSNumber *)generateSharedSecretWithOtherPublicKey:(NSNumber *)otherPublicKey;

@end

DiffieHellman.m


#import "DiffieHellman.h"

@implementation DiffieHellman

- (instancetype)initWithPrivateKey:(NSNumber *)privateKey base:(NSNumber *)ba
