CatCrypto include a series of hashing and encryption functions and more functions in progress!

CatCrypto also contains Swift bindings of Argon2, the password-hashing function that won the Password Hashing Competition (PHC).

Content

Requirements

  • Swift 4+
  • iOS 8.0+
  • macOS 10.10+
  • tvOS 9.0+
  • watchOS 2.0+

Support Functions

Upcoming Functions

  • Advanced Encryption Standard (AES)
  • Data Encryption Standard (DES)
  • Triple DES (3DES)

Usage

Context

Context contains inputs and configures for function crypto.

Change hash length with SHA-2 function crypto:

let sha2Crypto = CatSHA2Crypto()
sha2Crypto.context.hashLength = .bit384

Hashing

Hash function used to map data of arbitrary size to data of fixed size.

Simply hashing string with MD6 function crypto:

let md6Crypto = CatMD6Crypto()
md6Crypto.context.hashLength = .bit512
print(md6Crypto.hash(password: "CatCrypto").hexStringValue())

// 3ad3003383633c40281bb5185424ee56a5a1c6dfa3a0e7c3a9e381c58d253323e146feb3f04cb9ebcde47186e042ce63109b8d19f3ca760ea00c90654eb2b272

Verification

Some hash function support to verify their hashed value.

Verifing with Argon2 function crypto:

let hash = "$argon2i$v=19$m=4096,t=3,p=1$Q2F0Q3J5cHRv$Ad6gXMVLvZ3uQOeTi6nCmU4Ns2/nPDfPD5B3yyebv8k"
let argon2Crypto = CatArgon2Crypto()
argon2Crypto.context.mode = .argon2i
argon2Crypto.context.salt = "CatCrypto"
print(argon2Crypto.verify(hash: hash, password: "CatCrypto").boolValue())

// true
