java.security.NoSuchProviderException No such provider: BC

[mhimehdi]

Hi Kass, in some cases you may have the exception NoSuchProviderException BC, you'd better surround your code with try/catch statement and handle this exception by adding this portion of the code: Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider()); https://github.com/CryptoKass/NoobChain-Tutorial-Part-2/blob/a40ba474e090ce4af62b7230373d7446dcf20d3a/src/noobchain/Wallet.java#L21
