Examples with DecryptedDataTuple io.bisq.network.crypto.DecryptedDataTuple used on opensource projects

Example 1 with DecryptedDataTuple

use of io.bisq.network.crypto.DecryptedDataTuple in project bisq-api by mrosseel.

the class MainViewModelHeadless method checkCryptoSetup.

    // To avoid that we add here at startup a sample encryption and signing to see if it don't causes an exception.
