Listing the Aliases in a Key Store</h3>
A key store is a collection of keys and certificates. Each key or
certificate has a unique <font color="#0066ff"><i>alias</i></font> used to identify that key or
certificate in the key store. This example lists all the aliases in
a key store.
<pre>
try {
// Load the keystore in the user's home directory
File file = new File(System.getProperty("user.home") + File.separatorChar + ".keystore");
FileInputStream is = new FileInputStream(file);
KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
String password = <font color="#0066ff"><i>"my-keystore-password"</i></font>;
keystore.load(is, password.toCharArray());
// List the aliases
Enumeration enum = keystore.aliases();
for (; enum.hasMoreElements(); ) {
String alias = (String)enum.nextElement();
// Does alias refer to a private key?
boolean b = keystore.isKeyEntry(alias);
// Does alias refer to a trusted certificate?
b = keystore.isCertificateEntry(alias);
}
is.close();
} catch (java.security.cert.CertificateException e) {
} catch (NoSuchAlgorithmException e) {
} catch (FileNotFoundException e) {
// Keystore does not exist
} catch (KeyStoreException e) {
} catch (IOException e) {
}
</pre>
The aliases can also be listed using keytool:
<pre>
> keytool -list -storepass <font color="#0066ff"><i>my-keystore-password</i></font>
