Not necessarily. This may be a side-effect of performance improvements elsewhere. If you can show a realistic workload (not encryption) that is getting considerably slow, report it. It'll probably get a high priority. Encryption won't get high priority. > Ekke do you use prebuilt binaries or do you compile them yourself? > > If you compile yourself you can bisect and find the cause.

Re: [Interest] Qt 5.12 Beta 3 slows down ext Javascript library (RSA encrypt)
Still there is a performance regression somewhere and while the C++ solution is most performant the cause of this regression can hit other parts of Qml stack. Ekke do you use prebuilt binaries or do you compile them yourself? If you compile yourself you can bisect and find the cause.

Then get a 400x improvement by trying the C++ part again. OpenSSL is easy on Android, since you'll have to deploy it anyway alongside your application. On iOS and macOS, you shouldn't use OpenSSL. You should use Apple's API, whatever it is.

Thanks, Thiago for the hint - that was the first thing I tried, but
couldn't figure out HowTo make it work on Android and iOS.
It's only used when password has changed and must be entered: then
password must be RSA encrypted and base64 sent to server
so I was happy to find a JS solution which was implemented easy for
Android / iOS:
function doEncrypt() {
var rsa = new MyRsa.RSAKey();
rsa.setPublic(dataServer.modulusHex(), "10001")
var res = rsa.encrypt(pwText.text)
if(res) {
return MyRsa.linebrk(res, 64)
} else {
return ""
}
}
unfortunately now with 5.12 Beta it slows down by 20x.
on Android per ex. from 80 ms to 1700 ms (acceptable for my customer)
but iOS now is too slow

Re: [Interest] Qt 5.12 Beta 3 slows down ext Javascript library (RSA encrypt)
created a example app and now noticed, the app doesn't freeze,
but the exection of encrypt() slows down from
5 sec (Qt 5.11.2) to
92 sec (Qt 5.12 Beta3)
will open a bug report
