您应该使用 NAChloride（libsodium/NaCl）而不是它。这个用于高级加密。
以下使用 Apple 的 CommonCrypto 框架：
以下实现自包含的参考 C 库：
pod "NACrypto"NSData *mac1 = [NAHMAC HMACForKey:key data:data algorithm:NAHMACAlgorithmSHA2_512];
NSData *mac2 = [NAHMAC HMACForKey:key data:data algorithm:NAHMACAlgorithmSHA3F_512];// Nonce should be 16 bytes
// Key should be 32 bytes
NAAES *AES = [[NAAES alloc] initWithAlgorithm:NAAESAlgorithm256CTR];
NSData *encrypted = [AES encrypt:message nonce:nonce key:key error:&error];// Nonce should be 16 bytes
// Key should be 32 bytes
NATwoFish *twoFish = [[NATwoFish alloc] init];
NSData *encrypted = [twoFish encrypt:message nonce:nonce key:key error:&error];NSData *digest1 = [NADigest digestForData:data algorithm:NADigestAlgorithmSHA2_256];
NSData *digest2 = [NADigest digestForData:data algorithm:NADigestAlgorithmSHA3F_512];
// Directly use Keccak
NSData *sha = [NAKeccak SHA3ForData:data digestBitLength:512];NSData *key = [NASecRandom randomData:32 error:&error];
[NAKeychain addSymmetricKey:key applicationLabel:@"NACrypto" tag:nil label:nil];
NSData *keyOut = [NAKeychain symmetricKeyWithApplicationLabel:@"NACrypto"];NSData *data = [@"deadbeef" na_dataFromHexString];
[data na_hexString]; // @"deadbeef";
