Class Wallet

java.lang.Object

org.web3j.crypto.Wallet

public class Wallet
extends java.lang.Object

Ethereum wallet file management. For reference, refer to Web3 Secret Storage Definition or the Go Ethereum client implementation.

Note: we don't use the Bouncy Castle Scrypt implementation SCrypt, as the following parameter assertion results in failure of the Ethereum reference Scrypt test vector:

 
 // Only value of r that cost (as an int) could be exceeded for is 1
 if (r == 1 && N > 65536)
 {
     throw new IllegalArgumentException("Cost parameter N must be > 1 and < 65536.");
 }
