OTFUtilities

This is TheraForge's Utilities framework that provide various helper function.

OTFUtilities implements the functions required to perform e2e encryption using swift Sodium.

Master Key

Create a Master Key by using generateMasterKey funcion and pass email addrress and password.

let masterKey = swiftSodium.generateMasterKey(email: "your email address", password: "your password")

Create a Default Storage Key by using generateDefaultStorageKey funcion and pass your master key.

let defaultStorageKey = swiftSodium.generateDefaultStorageKey(masterKey: "your master key")

Create a Confidential Storage Key by using generateConfidentialStorageKey function and pass your master key.

let confidentialStorageKey = swiftSodium.generateConfidentialStorageKey(masterKey: "your master key")

Create a File Key by using generateDeriveKey function and pass your default storage key.

let fileKey = swiftSodium.generateDeriveKey(key: "your default storage key")

Create a GenericHash With Key by using generateGenericHashWithKey function and pass your document bytes and your file key.

let hashKeyUsingKey = swiftSodium.generateGenericHashWithKey(message: "your document bytes", fileKey: "your file key")

Create a GenericHash Without Key by using generateGenericHashWithoutKey function and pass your document bytes.

let hashKeyUsingKey = swiftSodium.generateGenericHashWithoutKey(message: "your document bytes")

You can save the key in your keychain by using saveKey function.

swiftSodium.saveKey(key: "your key bytes", keychainKey: "key name")

You can load the key from your keychain by using loadKey function.

swiftSodium.loadKey(keychainKey: "your key name")

You can encrypt your key by using encryptKey function and pass key bytes and recipient Public Key.

let encryptkey : Bytes? = swiftSodium.encryptKey(bytes: "key in bytes", publicKey: "recipient Public Key")

You can encrypt your key by using decryptKey function and pass encrypyted key bytes, recipient Public Key and recipient Secret Key.

let decrryptedKey =  swiftSodium.decryptKey(bytes: "encrypyted key bytes", publicKey: "recipient Public Key", secretKey: "recipient Secret Key")

You can encrypt your document by using encryptFile function and pass Push Stream Object and document in bytes.

let encryptedFile = swiftSodium.encryptFile(pushStream: "Push Stream Object", fileBytes: "document in bytes")

You can encrypt your document by using decryptFile function and pass Push Stream Header, file key and encrypted document in bytes.

guard let (file, tag) = swiftSodium.decryptFile(secretKey: "file key", header: "push stream header", encryptedFile: "encrypted File key")

you can create hexString To Data by using hexStringToData function.

let data = swiftSodium.hexStringToData(string: "hexString")
