Constructor Summary

CSR(PublicKey pubKey, PrivateKey privKey)
Constructs a Certificate Signing Request for the keypair using a default DUMMY_DN (="C=X, O=Y, CN=Z").

CSR(String subjectDN, PublicKey pubKey, PrivateKey privKey)
Constructs a Certificate Signing Request for the given keypair using specified subjectDN.

Method Summary

private String	bytetoString(byte[] bytes) returns a String representation of the given byte[] array.
String	hash() Returns the SHA1 hash for the DER encoded CSR.
String	pemString() Returns a PEMstring for the CSR as a URL encoded (UTF-8) String.

CSR

public CSR(String subjectDN,
           PublicKey pubKey,
           PrivateKey privKey)
    throws NoSuchAlgorithmException,
           NoSuchProviderException,
           InvalidKeyException,
           SignatureException

Constructs a Certificate Signing Request for the given keypair using specified subjectDN. It uses SHA1/RSA as signature algorithm.

Parameters:

subjectDN - specifies the subject DN to use for signing request.

pubKey - specifies public key of keypair to use for signing request.

privKey - specifies private key of keypair to use for signing request.

Throws:

NoSuchAlgorithmException

NoSuchProviderException

InvalidKeyException

SignatureException

    throws NoSuchAlgorithmException,
           NoSuchProviderException,
           InvalidKeyException,
           SignatureException

Constructs a Certificate Signing Request for the keypair using a default DUMMY_DN (="C=X, O=Y, CN=Z").

Parameters:

pubKey - specifies public key of keypair to use for signing request

privKey - specifies private key of keypair to use for signing request

Throws:

NoSuchAlgorithmException

Method Detail

pemString

public String pemString()
                 throws IOException

Returns a PEMstring for the CSR as a URL encoded (UTF-8) String.

Returns:

String representing URL encoded PEMstring.

Throws:

IOException - if construction of PEMstring fails

URLEncoder, PEMWriter

hash

public String hash()
            throws IOException

Returns the SHA1 hash for the DER encoded CSR.

Returns:

String containing the SHA1 hash for the DER encoding.

Throws:

IOException - if construction of hash fails

bytetoString

private String bytetoString(byte[] bytes)

returns a String representation of the given byte[] array. In Java 1.5 and higher this can be done using String.format(java.lang.String, java.lang.Object...)("%02x",bytes[i]).

Parameters:

bytes - byte[] array to convert

Returns:

String representing the byte[] array
