Hi~
Method processing takes a long time.

It always takes over 3 seconds to run ( restoreKeyPairFrom, verify method )
I would like to know release optimization Config info.

my Xcode build Settings.

• Complilation Mode : wholemodule
• SWIFT_OPTIMIZATION_LEVEL (debug) : -Onone
• append User-Define option
  SWIFT_WHOLE_MODULE_OPTIMIZATION = YES

Do you have any more settings info?

Hello!
Your lib perfectly matches to my goals, but I have trouble with Message from your example:
let message = Message(hex: "243F6A8885A308D313198A2E03707344A4093822299F31D0082EFA98EC4E6C89" An error occurred： Cannot invoke initializer for type 'Message' with an argument list of type '(hex: String)'

How could I init Message with some String?

Hello!
I see the minimum supported iOS version 11.2 in the .podspec file. Why? 🤔
Because our project needs to support iOS 10.0.

English is not my native language; please excuse typing errors.

I just need to use pk to verify, but there are only recover keypair function to verify

Hi, I'm still using your library for my project and it works great, the the app which I'm porting from Android to iOS is communicating with a 3rd Party endpoint and in one of the recent updates they switched from Secp256K1 to Secp521R1. Do you have plans to add this curve Algo?

Hi,

I'm currently porting my Android app to iOS and I stumbled across your library which seems to perfectly meet my requirements. I'm not sure if I do something wrong but I'm not able to create a public key from Data. I have created a Unit test to check if the output of some crypto functions is the same as in my Android app. Therefore I use following uncompressed public key. Below the uncompressed public key in hex representation

04F40AF135A4889436CEE52B5C73A33EC5AD0BE0952F57F4F0ED0C80B0BEDA7CA643789393A5947E9FAA3F6795C9AA09A96325DFE850BFC3F1DB62A50ABFB0FFF7

Once converted the hex string to Data I use following function calls

let decodedFromUncompressed = try AffinePoint<Secp256k1>.init(data: publicKeyBytes)
return PublicKey<Secp256k1>.init(point: decodedFromUncompressed)

This leads to an error here

Upon further investigation I saw that the call

let yData = y.as256bitLongData()

returned 0 despite the value is not 0. It seems the as256bitLongData uses internally a function called asHexStringLength64 which returns following strange hex value

0-789393A5947E9FAA3F6795C9AA09A96325DFE850BFC3F1DB62A50ABFB0FFF7

The function fills up the missing values with 0 but seems to ignore the '-' sign. Is this the root cause of the error, did I misunderstand something or is there another way to get a PublicKey from uncompressed Data?
