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.

let message = Message(hex: "243F6A8885A308D313198A2E03707344A4093822299F31D0082EFA98EC4E6C89"
An error occurred：
Cannot invoke initializer for type 'Message' with an argument list of type '(hex: String)'

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~
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?

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?

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