I need to to ECDSA sign a QByteArray and to recover the public key from it. Is there something in Qt which I can use for this purpose?

Not my area, but is https://doc.qt.io/qt-5/qsslkey.html#QSslKey-1 what you are looking for? https://doc.qt.io/qt-5/qssl.html#KeyAlgorithm-enum has QSsl::Dsa and QSsl::Ec.

@JonB Thanks, but this is not what I'm looking for. I would like to retrieve the public key from an ECDSA signature.
