Removing your Podfile. Which version you use depends on which version of Xcode and Swift you are currently using. Please refer to the list below:. To calculate a message digest you create an instance of Digest , call update one or more times with the data over which the digest is being calculated and finally call final to obtain the digest itself.
Calculating a keyed-Hash Message Authentication Code HMAC is very similar to calculating a message digest, except that the initialization routine now takes a key as well as an algorithm parameter. To encrypt a large file or a network stream use StreamCryptor. The StreamCryptor class does not accumulate the encrypted or decrypted data, instead each call to update produces an output buffer. The example below shows how to use StreamCryptor to encrypt and decrypt an image file.
The following example derives a byte key:. Input Calendars Picker Switch Text. Add a comment. Sorted by: Reset to default. Highest score default Date modified newest first Date created oldest first.

Apple platforms offer a comprehensive set of low-level APIs for developing cryptographic solutions within your apps. The Common Crypto library supports symmetric encryption, hash-based message authentication codes, and digests. The CryptoTokenKit framework provides first-class access for working with smart cards and other cryptographic devices in macOS. Both the Security framework and Common Crypto rely on the corecrypto library to provide implementations of low-level cryptographic primitives.
This is also the library submitted for validation of compliance with U. Visit the Security Certifications and Compliance Center for up-to-date information on corecrypto validations. Although corecrypto does not directly provide programming interfaces for developers and should not be used by iOS, iPadOS, or macOS apps, the source code is available to allow for verification of its security characteristics and correct functioning.

View in English. Face ID and Touch ID These secure ways to unlock, authenticate, and pay let users quickly access your app with just a glance or a touch of their finger. Making secure connections A range of APIs on Apple platforms enables your apps to employ secure network connections and to benefit from OS-level security policies. Protecting user data Apple platforms provide a variety of features for protecting user data.
Purpose strings Purpose strings let you statically declare the sensitive data and resources your app employs. API guidance for using purpose strings Information Property List Key Reference Copying and pasting sensitive data Take advantage of privacy options when allowing users to copy and paste sensitive data in your apps on iPhone or iPad. UIPasteboard Class Reference. Keychain and iCloud Keychain Keychain and iCloud Keychain provide a secure repository for sensitive user data, such as certificates, keys, passwords, and notes.
App Sandbox. All these keys are going to be saved in the Keychain using the TouchID protection. Note: if the device doesn't support TouchID an Application Password is required to protect these keys. If you use the default options you can simply call the aeEncryptData:completion:failure: method with your plaintext data.
If you don't want to generate random keys, you can use a simple text password with the aeEncryptData:password:completion:failure: method. This alleviates the headache of saving IVs and Salts. If you use the default options you can simply call the aeDecryptData:completion:failure: method with your ciphertext:. Decrypting with your own keys using the aeDecryptData:symmetricKey:hmacKey:completion:failure: method:.
And of course you can decrypt using a password with the aeDecryptData:password:completion:failure: method:. Note that these methods provide confidentiality but not integrity against active attacks. Also while using this methods you need to remember to save the correspongind IVs and Salts. If you use the default options you can simply call the encryptData:completion:failure: method with your plaintext data remember to save the returned IV for decryption :.
You can also encrypt with your own key using the encryptData:withKey:completion:failure: method:. Same as with AEAD, if you don't want to generate a random key, you can use a simple text password with the encryptData:withPassword:completion:failure: method be aware of the fact that in this case you also need to save the salt for decryption :. If you use the default options you can simply call the decryptData:iv:completion:failure: method with your ciphertext and the iv returned during encryption:.
Decrypting with your own key using the decryptData:withKey:iv:completion:failure: method:. Decrypting using a password with the decryptData:withPassword:iv:salt:completion:failure: method:. Again, this is a learning experiment, if you find issues or want to add more features I'll be happy to merge your pull requests :.
Why am I creating this library then? Short answer: I want to learn. Although this library is not intended to be used in real world applications maybe in the future? That being said, if you find any issues please let me know, I'll fix them and we can all learn from it.

This oft quoted wisdom isn't really applicable in your case since you are just wrapping Apple's API instead of implementing crypto from scratch. You have to be careful about your wrapper introducing new vulnerabilities i. As you mentioned, it is always a good idea to have code reviewed by someone. I'm not much of a Objective-C person and I haven't read through all of your code, but so far your abstraction looks pretty clean to me - nice work!
Resource links. Travis setup. Added hashing SHA method. Added documentation to IRCrypto header file. Source code tar. Fixed keychain item attributes for saved keys.
Compute and compare cryptographically secure digests. · Use public-key cryptography to create and evaluate digital signatures, and to perform key exchange. Apple CryptoKit was released with iOS 13 and is built on top of Apple's native cryptographic library corecrypto. The Swift framework provides a strongly typed. Apple's new CryptoKit API provides you the ability to authenticate and encrypt data sent and received by your app, if your app needs more.
