Package org.xrpl.xrpl4j.crypto.signing

Class SingleKeySignatureService

java.lang.Object

org.xrpl.xrpl4j.crypto.signing.AbstractSignatureService

org.xrpl.xrpl4j.crypto.signing.SingleKeySignatureService

All Implemented Interfaces:

SignatureService, TransactionSigner, TransactionVerifier

public class SingleKeySignatureService
extends AbstractSignatureService
implements SignatureService

A SignatureService that holds a single private key, in-memory, using BouncyCastle as the underlying crypto implementation.

WARNING: This implementation _might_ be appropriate for Android use, but should likely not be used in a server-side context. In general, prefer an implementation that offers a higher level of security.
