## org.bouncycastle.asn1.cmp
Class Challenge

    java.lang.Object
      org.bouncycastle.asn1.ASN1Object

All Implemented Interfaces:
  ASN1Encodable, Encodable

public class Challenge
extends ASN1Object

Challenge ::= SEQUENCE { owf AlgorithmIdentifier OPTIONAL, -- MUST be present in the first Challenge; MAY be omitted in -- any subsequent Challenge in POPODecKeyChallContent (if -- omitted, then the owf used in the immediately preceding -- Challenge is to be used). witness OCTET STRING, -- the result of applying the one-way function (owf) to a -- randomly-generated INTEGER, A. [Note that a different -- INTEGER MUST be used for each Challenge.] challenge OCTET STRING -- deprecated -- the encryption (under the public key for which the cert. -- request is being made) of Rand encryptedRand [0] EnvelopedData OPTIONAL } Rand ::= SEQUENCE { int INTEGER, -- the randomly-generated INTEGER A (above) sender GeneralName -- the sender's name (as included in PKIHeader) }
