Field Detail

signerKey_

protected java.security.PrivateKey signerKey_

The private key of the signer. In this case only a proxy object, but the application cannot see this.

signerCertificates_

protected iaik.x509.X509Certificate[] signerCertificates_

The certificate chain of the signer. In contrast to the private signer key, the certificate holds the actual public keying material.

sender_

protected java.lang.String sender_

The email address of the sender.

protected java.lang.String recipient_

The email address of the recipient.

Constructor Detail

SignedMailDemo

protected SignedMailDemo(java.lang.String moduleName,
                         char[] userPin)

Creates a SignedMailDemo object for the given module name.

Parameters:

moduleName - the name of the module

userPin - the user-pin (password) for the TokenKeyStore (may be null to pou-up a dialog asking for the pin)

Method Detail

getSignatureKey

protected void getSignatureKey()
                        throws java.security.GeneralSecurityException,
                               java.io.IOException

This method gets the key stores of all inserted (compatible) smart cards and simply takes the first key-entry. From this key entry it takes the private key and the certificate to retrieve the public key from. The keys are stored in the member variables signerKey_ and signerCertificate_.

Throws:

java.security.GeneralSecurityException - If anything with the provider fails.

java.io.IOException - If loading the key store fails.

createSignedMessage

protected javax.mail.internet.MimeMessage createSignedMessage(javax.mail.Session session,
                                                              javax.activation.DataHandler dataHandler,
                                                              boolean implicit)
                                                       throws javax.mail.MessagingException

Creates a signed message.

Parameters:

session - the mail session

dataHandler - the content of the message to be signed

implicit - whether to use implicit (application/pkcs7-mime) or explicit (multipart/signed) signing

Returns:

the signed message

Throws:

javax.mail.MessagingException - if an error occurs when creating the message

start

protected void start(boolean implicit)
              throws java.lang.Exception

Starts the demo.

Parameters:

implicit - whether to create an implicit (content included; application/pkcs7-mime) or an explicit (content not included; multipart/signed) signed message

Throws:

java.lang.Exception - if an error occurs
