Method

KeyManagerFactorygetKeyManagerFactory(KeyStore keystore, String password)
Given a keystore and keystore password (as generated by #pemsToKeyAndTrustStores ), return a key manager factory that contains the keystore. 
KeyManagerFactory factory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
factory.init(keystore, password.toCharArray());
return factory;

get Key Manager Factory 
KeyManagerFactory kmFactory = null;
try {
    kmFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
    kmFactory.init(store, password);
} catch (NoSuchAlgorithmException nsae) {
return kmFactory;
KeyManagerFactorygetKeyManagerFactory(Map stores)
get Key Manager Factory 
KeyStore keystore = (KeyStore) stores.get("keystore");
String password = (String) stores.get("keystore-pw");
return getKeyManagerFactory(keystore, password);
KeyManager[]getKeyManagers()
get Key Managers 
String pass = "lib.pass";
try {
    KeyStore keyStore = KeyStore.getInstance("JKS");
    keyStore.load(new FileInputStream("keystore.jks"), pass.toCharArray());
    KeyManagerFactory keyManagerFactory = KeyManagerFactory
            .getInstance(KeyManagerFactory.getDefaultAlgorithm());
    keyManagerFactory.init(keyStore, pass.toCharArray());
    return keyManagerFactory.getKeyManagers();

KeyManager[]getKeyManagers(KeyStore keyStore, String keyPassword)
get Key Managers 
String alg = KeyManagerFactory.getDefaultAlgorithm();
char[] keyPass = keyPassword != null ? keyPassword.toCharArray() : null;
KeyManagerFactory fac = KeyManagerFactory.getInstance(alg);
fac.init(keyStore, keyPass);
return fac.getKeyManagers();
KeyManager[]getKeyManagers(KeyStore ks, String password)
get Key Managers 
KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
kmf.init(ks, password.toCharArray());
return kmf.getKeyManagers();
KeyPairgetKeyPair()
get Key Pair 
KeyPairGenerator kpGenerator = KeyPairGenerator.getInstance(KEY_ALGORITHM);
kpGenerator.initialize(KEY_SIZE);
KeyPair keyPair = kpGenerator.generateKeyPair();
return keyPair;
KeyPairgetKeyPair()
The method gets the key pair. 
return kpg.genKeyPair();
KeyPairgetKeyPair()
Generate a RSA key pair. 
KeyPairGenerator keyGen = null;
SecureRandom random = null;
try {
    keyGen = KeyPairGenerator.getInstance("RSA");
    random = SecureRandom.getInstance("SHA1PRNG", "SUN");
    keyGen.initialize(1024, random);
} catch (NoSuchAlgorithmException e) {
} catch (NoSuchProviderException e) {
...
KeyPairgetKeyPair(KeyStore keyStore, String alias, String password)
get Key Pair 
Key key = keyStore.getKey(alias, password.toCharArray());
if (key instanceof PrivateKey) {
    Certificate cert = keyStore.getCertificate(alias);
    PublicKey publicKey = cert.getPublicKey();
    return new KeyPair(publicKey, (PrivateKey) key);
return null;
