KeyChainManager

KeychainManager is a Swift library that provides a convenient way to securely store and retrieve data in the keychain. It allows you to save and retrieve email and password values associated with unique keys. The library utilizes the Security framework to interact with the keychain.

Installation

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.

Once you have your Swift package set up, adding KeyChainManager as a dependency is as easy as adding it to the dependencies value of your Package.swift.

dependencies: [
    .package(url: "https://github.com/abbasjoyia99/KeyChainManager.git", .upToNextMajor(from: "2.0.1"))
]

Manually

If you prefer not to use any of the aforementioned dependency managers, you can integrate KeychainManager into your project manually.

1 Download zip file
2 Open KeyChainManager/Sources/KeyChainManager
3 Drag and drop KeyChainManager.swift file into project

Usage

To use the KeychainManager library, follow these steps:

1 Import the KeychainManager module in the file where you want to use it:

import KeychainManager

Generic Data

Saving Generic Data

To save data securely in the keychain, use the saveData(data:forKey:) method:

let keychain = KeychainManager.shared
let email = "[email protected]"

// Save the email securely in the keychain
let success = keychain.saveData(data: email, forKey: "userEmail")

if success {
    print("Email saved successfully.")
} else {
    print("Failed to save email.")
}

Retrieving Generic Data

To retrieve data from the keychain, use the getData(type:forKey:) method:

let keychain = KeychainManager.shared

// Retrieve the saved email from the keychain
if let email: String = keychain.getData(type: String.self, forKey: "userEmail") {
    print("Retrieved email: \(email)")
} else {
    print("Email not found in the keychain.")
}

Updating Generic Data

To update existing data in the keychain, use the updateData(data:forKey:) method:

let keychain = KeychainManager.shared
let newEmail = "[email protected]"

// Update the email in the keychain
let success = keychain.updateData(data: newEmail, forKey: "userEmail")

if success {
    print("Email updated successfully.")
} else {
    print("Failed to update email.")
}

Deleting Generic Data

To delete data from the keychain, use the deleteData(forKey:) method:

let keychain = KeychainManager.shared

// Delete the email from the keychain
let success = keychain.deleteData(forKey: "userEmail")

if success {
    print("Email deleted successfully.")
} else {
    print("Failed to delete email.")
}

2 Save data securely in the keychain:

let key = "emailKey"
let email = "[email protected]"

let success = KeychainManager.shared.saveEmail(email: email, forKey: key)
if success {
    print("Email saved successfully!")
} else {
    print("Failed to save email.")
}

3 Retrieve data securely from the keychain:

let key = "emailKey"

if let email = KeychainManager.shared.getEmail(forKey: key) {
    print("Retrieved email: \(email)")
} else {
    print("Email not found in the keychain.")
}

4 Update data in the keychain:

let key = "emailKey"
let newEmail = "[email protected]"

let success = KeychainManager.shared.updateEmail(newEmail: newEmail, forKey: key)
if success {
    print("Email updated successfully!")
} else {
    print("Failed to update email.")
}

5 Delete data from the keychain::

let key = "emailKey"

let success = KeychainManager.shared.deleteEmail(forKey: key)
if success {
    print("Email deleted successfully!")
} else {
    print("Failed to delete email.")
}
