I am relatively new to Swift and i\'m stuck encrypting using HMAC and SHA1. I Found the following answer https://stackoverflow.com/a/24411522/4188344 but i can\'t work out h

Answer 1

I have checked the above answers and found it so lengthy.

Solution: I got third party: IDZSwiftCommonCrypto

Use pod: pod 'IDZSwiftCommonCrypto'

and use the following function to achieve desired output:

func getHMacSHA1(forMessage message: String, key: String) -> String? {
    let hMacVal = HMAC(algorithm: HMAC.Algorithm.sha1, key: key).update(string: message)?.final()
    if let encryptedData = hMacVal {
        let decData = NSData(bytes: encryptedData, length: Int(encryptedData.count))
        let base64String = decData.base64EncodedString(options: .lineLength64Characters)
        print("base64String: \(base64String)")
        return base64String
    } else {
        return nil
    }
}
