NACrypto 1.1.0

You want to add pod 'NACrypto', '~> 1.1' similar to the following to your Podfile:

target 'MyApp' do
  pod 'NACrypto', '~> 1.1'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try NACrypto

You should be using NAChloride (libsodium/NaCl) instead. This is for advanced crypto only.

The following use Apple's CommonCrypto framework:

HMAC: SHA1, SHA2
Digest: SHA2
AES (256-CTR)

The following are implemented from included reference C libraries:

HMAC: SHA3, Keccak
Digest: SHA3, Keccak
TwoFish (CTR)

Podfile

pod "NACrypto"

HMAC (SHA1, SHA2, SHA3, Keccak)

NSData *mac1 = [NAHMAC HMACForKey:key data:data algorithm:NAHMACAlgorithmSHA2_512];
NSData *mac2 = [NAHMAC HMACForKey:key data:data algorithm:NAHMACAlgorithmSHA3F_512];

AES (256-CTR)

// 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];

TwoFish (CTR)

// 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];

Digest (SHA2, SHA3, Keccak)

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];

Keychain Utils

NSData *key = [NASecRandom randomData:32 error:&error];
[NAKeychain addSymmetricKey:key applicationLabel:@"NACrypto" tag:nil label:nil];
NSData *keyOut = [NAKeychain symmetricKeyWithApplicationLabel:@"NACrypto"];

NSData Utils

NSData *data = [@"deadbeef" na_dataFromHexString];
[data na_hexString]; // @"deadbeef";
