Example usage for org.bouncycastle.asn1 ASN1InputStream ASN1InputStream

Introduction

In this page you can find the example usage for org.bouncycastle.asn1 ASN1InputStream ASN1InputStream.

Prototype

public ASN1InputStream(InputStream input, int limit, boolean lazyEvaluate) 

Source Link

Document

Create an ASN1InputStream where no DER object will be longer than limit, and constructed objects such as sequences will be parsed lazily.

/**
