Examples with SealedAndSigned bisq.common.crypto.SealedAndSigned used on opensource projects

Example 1 with SealedAndSigned

use of bisq.common.crypto.SealedAndSigned in project bisq-desktop by bisq-network.

the class MainViewModel method checkCryptoSetup.

    // and if the unlimited Strength for cryptographic keys is set.
    // If users compile themselves they might miss that step and then would get an exception in the trade.
    // To avoid that we add here at startup a sample encryption and signing to see if it don't causes an exception.
