Usage

Hash

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);

File 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);

Symmetric Encrypt

// 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

Get Key String And Encryption

- (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]);
