infinity waiting when rsa sign

[cwangfr]

Hi, I have a strange problem here. When I use the RSA SignPSS feature, there is an infinite wait.
I use Android Studio, use usb cable connect with my Samsung Tab7.
If I start program on device, keep usb cable connect, the function always ok,
but, when I start program, and then disconnect the usb cable, the signPSS could not return result.
here is my code :

final _pkcs12KeyPair = await RSA.convertPKCS12ToKeyPair(
    (await rootBundle.loadString('assets/key.base64')), "miipos");
var signature = await RSA.signPSS(
    value, Hash.SHA512, SaltLength.AUTO, _pkcs12KeyPair.privateKey); // always waiting there, never return the result signature

var result = signature.replaceAll("+", "-").replaceAll("/", "_");
debugPrint(result);
debugPrint("****** end sign ******");

thanks

Hi @zaqzaq163 , @cwangfr thanks for report this issue, please could you provide a full example to help me to reproduce it here

Hi @jerson, I use IOS device, when I transfer code from swift to objective-c and submit to testflight, signPKCS1v15 can't return result and wait infinitely

@zaqzaq163 which version are you using?

[zaqzaq163]

I have tested version 3.5.3 and 3.5.6, it doesn't work

Hi @zaqzaq163 I'm still trying to reproduce it, but I couldn't, could you provide me a full example with a sample private key or a pkcs12 and the arguments you are using

@zaqzaq163 I just released a new version, please take a look when you get a chance https://pub.dev/packages/fast_rsa/versions/3.5.7 if doesn't work either please send me a full example to try to reproduce it here, thank you.
