Class NetscapeCertRequest

java.lang.Object

iaik.x509.NetscapeCertRequest

All Implemented Interfaces:

CertRequest

public class NetscapeCertRequest
extends java.lang.Object
implements CertRequest

This class represents a certificate request coming from Netscape Navigator 3.0 and 4.x.

This class only can be used for parsing an already existing NetscapeCertRequest, supplied in DER or PEM encoded format. Therefore this class provides two constructors for creating a NetscapeCertRequest from an InputStream, or from byte array supplying the PEM or DER encoded request. The given data is decoded and "translated" into a "SignedPublicKeyAndChallange" ASN.1 data structure as defined by the Netscape Certificate Specifications:

 SignedPublicKeyAndChallenge ::= SEQUENCE {
    publicKeyAndChallenge PublicKeyAndChallenge,
    signatureAlgorithm AlgorithmIdentifier,
    signature BIT STRING
 }
 

where:

 PublicKeyAndChallenge ::= SEQUENCE {
    spki SubjectPublicKeyInfo,
    challenge IA5STRING
 }
 

For obtaining the public key from this "SignedPublicKeyAndChallange" structure, use the getPublicKey method. The self-signed "SignedPublicKeyAndChallange" structure can be verified using the verify method.

Constructor Detail

NetscapeCertRequest

public NetscapeCertRequest(java.io.InputStream is)
                    throws java.io.IOException,
                           CodingException

Creates a NetscapeCertRequest from an InputStream supplying the PEM or DER encoded request.

From the request derived from the given input stream the "SignedPublicKeyAndChallange" ASN.1 data structure is created.

Parameters:

is - the input stream from where to read the PEM/DER encoded cert request

Throws:

java.io.IOException - if an I/O error occurs.

CodingException - if the CertRequest could not be parsed

NetscapeCertRequest

public NetscapeCertRequest(byte[] arr)
                    throws CodingException

Creates a NetscapeCertRequest from a byte array supplying the PEM or DER encoded request.

From the request derived from the given byte array the "SignedPublicKeyAndChallange" ASN.1 data structure is created.

Parameters:

arr - the array containing the DER/PEM encoded CertRequest

Throws:

CodingException - if the CertRequest could not be parsed

Method Detail

verify

public boolean verify()
               throws java.security.SignatureException

Verifies the self signed certificate request.

Specified by:

verify in interface CertRequest

Returns:

true if the cert request is OK, false if not

Throws:

java.security.SignatureException - if the cert request could not be verified

getPublicKey

public java.security.PublicKey getPublicKey()
                                     throws java.security.InvalidKeyException

Returns the public key from this "SignedPublicKeyAndChallange" structure.

Specified by:

getPublicKey in interface CertRequest

Returns:

the public key from this "SignedPublicKeyAndChallange" structure

Throws:

java.security.InvalidKeyException - if the public key from this "SignedPublicKeyAndChallange" structure cannot not be created
