Class CertRequest

java.lang.Object

COM.claymoresystems.cert.CertRequest

public class CertRequest
extends java.lang.Object

Generate various kinds of certificate signing requests.

The three main interfaces are
makeSPKACRequest()
makePKCS10Request()
makeSelfSignedCert()

You can access these in a primitive fashion through the main() function but this gives you a mostly hardcoded DN with PKCS10 and self-signed (you can choose the CN). makeSimpleDN() offers a way to construct a fairly simple DN from a simpler construct than the standard X509Name. At some point we may expose simpler functionality at the command line.

Method Detail

generateKey

public static java.security.KeyPair generateKey(java.lang.String type,
                                int size,
                                java.lang.String password,
                                java.io.BufferedWriter keyfile,
                                boolean newParams)
                                         throws java.security.NoSuchAlgorithmException,
                                                java.security.NoSuchProviderException,
                                                java.io.IOException

Generate a key pair

Parameters:

type - DSA or RSA

size - the length

password - the password to use to encrypted the key

keyfile - the keyfile to store the key in

newParams - generate new parameters if using DSA--by default Sun uses fixed precomputed params

Returns:

the keypair

Throws:

java.security.NoSuchAlgorithmException - if you choose a key we don't know about

java.security.NoSuchProviderException - internal errors

java.io.IOException - encoding errors

makeSPKACRequest

public static byte[] makeSPKACRequest(java.security.KeyPair p)
                               throws java.io.IOException

Make a Netscape Signed Public Key and Cert request

Parameters:

p - the keypair to make it with

Returns:

the SPKAC as a bytestring

Throws:

java.io.IOException - for errors

makePKCS10Request

public static byte[] makePKCS10Request(java.security.KeyPair p,
                       X509Name name)
                                throws java.io.IOException

Make a PKCS10 CSR

Parameters:

p - the keypair to make it with

name - the subject name as an X509Name

Returns:

the CSR as a bytestring

Throws:

java.io.IOException - for errors

makeSelfSignedCert

public static byte[] makeSelfSignedCert(java.security.KeyPair p,
                        X509Name name,
                        int lifetime)
                                 throws java.io.IOException

Make a Self-signed cert

Parameters:

p - the keypair to make it with

the - name to use

the - lifetime in seconds

Returns:

the CSR as a bytestring

Throws:

java.io.IOException - for errors

makeSimpleDN

public static X509Name makeSimpleDN(java.util.Vector rdns)

fitSignature
