The toolkit can hold key stores in memory for situations where you prefer not to save credentials and certificates in a file.

See a full example in the following folder.

etjava\examples\source\com\entrust\toolkit\examples\keystoreInMemory

Loading credentials for memory

Create a key store and load credentials from a data structure in memory – for example, a bit array.

java.security.KeyStore.KeyStore keyStore = KeyStore.getInstance("Entrust");
keyStore.load(new ByteArrayInputStream(byteArray), 
password.toCharArray());

Adding certificates

Add a trusted certificate to the key store.

keyStore.setCertificate("Bob", cert);

Where "Bob" is the certificate alias, and cert is the certificate as an instance of the following class.

java.security.cert.Certificate

Retrieving certificates

Use the certificate aliases to retrieve certificates from the key store.

X509Certificate caCert = (X509Certificate)keyStore.getCertificate("CA");
X509Certificate encCert = (X509Certificate)keyStore.getCertificate("encryption");
X509Certificate signCert = (X509Certificate)keyStore.getCertificate("signing");
X509Certificate signCert = (X509Certificate)keyStore.getCertificate("Bob");

Writing the key store

Write the key store to a ByteArrayInputStream.

ByteArrayOutputStream anotherBaos = new ByteArrayOutputStream();
keyStore.store(anotherBaos, password.getStringBuffer().toString().toCharArray());
