public class Wallet
extends Object

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

Note: the Bouncy Castle Scrypt implementation SCrypt, fails to comply with the following Ethereum reference Scrypt test vector:

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