示例

要运行示例项目，请克隆仓库，然后首先从示例目录中运行 pod install。

要求

最低 iOS 目标是 iOS 10。

安装

YFEncrypt 通过 CocoaPods 提供。要安装它，只需将以下行添加到 Podfile 中即可。

pod 'YFEncrypt'

用法

哈希

MD5

NSLog(@"%@", [@"hello, world!" yf_md5String]);

Hmac SHA512

YFHashEncrypt *encryptor = [[YFHashEncrypt alloc] initWithType:YFHashTypeSHA512];
encryptor.contentData = [@"hello, world!" dataUsingEncoding:NSUTF8StringEncoding];
encryptor.keyData = [@"hmac key" dataUsingEncoding:NSUTF8StringEncoding];
NSString *result = [encryptor getHashString];
NSLog(@"result: %@", result);

文件 SHA256

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"private" ofType:@"pem"];
YFHashEncrypt *encryptor = [[YFHashEncrypt alloc] initWithType:YFHashTypeSHA256];
encryptor.filePath = filePath;
NSString *fileResult = [encryptor getHashString];
NSLog(@"fileResult: %@", fileResult);

对称加密

// random key
NSData *aes256KeyData = [NSData yf_randomDataWithLength:32];
NSString *aesKey = [aes256KeyData yf_base64Encode];
NSLog(@"aesKey: %@", aesKey);

NSString *testString = @"hello, world!";
YFSymmetricEncrypt *encryptor = [[YFSymmetricEncrypt alloc] initWithType:YFSymmetricEncryptTypeAES];

// encryption
NSData *resultData = [encryptor operationData:[testString dataUsingEncoding:NSUTF8StringEncoding] keyData:aes256KeyData isEncrypt:YES];
NSLog(@"encryptResult: %@", [resultData yf_base64Encode]);

NSString *result = [encryptor encryptString:testString withKey:aesKey];
NSLog(@"encryptResult: %@", result);

result = [testString yf_AESEncryptByKey:aesKey];
NSLog(@"encryptResult: %@", result);

// decryption
NSData *decryptData = [encryptor operationData:resultData keyData:aes256KeyData isEncrypt:NO];
NSLog(@"decryptResult: %@", [[NSString alloc] initWithData:decryptData encoding:NSUTF8StringEncoding]);

decryptData = [encryptor decryptString:result withKey:aesKey];
NSLog(@"decryptResult: %@", [[NSString alloc] initWithData:decryptData encoding:NSUTF8StringEncoding]);

decryptData = [result yf_AESDecryptByKey:aesKey];
NSLog(@"decryptResult: %@", [[NSString alloc] initWithData:decryptData encoding:NSUTF8StringEncoding]);

RSA

获取密钥字符串和加密

- (void)verifyRSAEncrypt:(YFRSAEncrypt *)encryptor {
    NSLog(@"public key: %@", [encryptor getPublicKey]);
    NSLog(@"private key: %@", [encryptor getPrivateKey]);
    
    NSString *result = [encryptor encryptData:[@"hello" dataUsingEncoding:NSUTF8StringEncoding] isPublicKey:YES];
    NSLog(@"encryptResult: %@", result);
    
    NSData *decryptData = [encryptor decryptString:result isPublicKey:NO];
    NSLog(@"decryptResult: %@", [[NSString alloc] initWithData:decryptData encoding:NSUTF8StringEncoding]);
}

加载 P12 和 DER 文件

YFRSAEncrypt *encryptor = [[YFRSAEncrypt alloc] init];
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"p" ofType:@"p12"];
[encryptor loadP12File:filePath password:@"123456"];

filePath = [[NSBundle mainBundle] pathForResource:@"rsacert" ofType:@"der"];
[encryptor loadDerFile:filePath];

[self verifyRSAEncrypt:encryptor];

加载密钥字符串

NSString *privateKey = @"-----BEGIN RSA PRIVATE KEY-----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-----END RSA PRIVATE KEY-----";

YFRSAEncrypt *encryptor = [[YFRSAEncrypt alloc] init];
[encryptor loadPublicKey:publicKey];
[encryptor loadPrivateKey:privateKey];

[self verifyRSAEncrypt:encryptor];

加载 Pem 文件

YFRSAEncrypt *encryptor = [[YFRSAEncrypt alloc] init];

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"private" ofType:@"pem"];
[encryptor loadPrivateKeyFromPemFile:filePath];

filePath = [[NSBundle mainBundle] pathForResource:@"public" ofType:@"pem"];
[encryptor loadPublicKeyFromPemFile:filePath];

[self verifyRSAEncrypt:encryptor];
