    <p>I am really baffled as to why the encoded values are different </p> <p>Heres the complete code</p> <pre><code>import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.InputStream; import java.security.Key; import java.security.KeyStore; import javax.crypto.KeyGenerator; import javax.crypto.SecretKey; import org.bouncycastle.util.encoders.Base64; public class KeyStoreDemo { private static final String KEY_STORE_TYPE = "JCEKS"; private static final String KEY_STORE_NAME = "sampleKeyStore.store"; private static final String KEY_STORE_PASSWORD = "letmein"; public static void main(String[] args) throws Exception { File storeFile = new File(KEY_STORE_NAME); storeFile.createNewFile(); //Create a keystore createKeyStore(KEY_STORE_TYPE, storeFile,KEY_STORE_PASSWORD); //Generate a key and store it in keystore KeyStore keyStore = loadKeyStore(KEY_STORE_TYPE,storeFile,KEY_STORE_PASSWORD); // Get the KeyGenerator KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");keyGenerator.init(128); Key keytemp = keyGenerator.generateKey(); System.out.println("key- Base64 before:"+Base64.encode (keytemp.getEncoded()) ); //createSecretKeyAndStore( keyStore, keytemp, "samplekey" ,"samplepwd"); createSecretKeyAndStore(storeFile, keyStore, KEY_STORE_PASSWORD, keytemp, "samplekey" ,"samplepwd"); Key key = getKeyFromStore(keyStore, "samplekey", "samplepwd"); System.out.println("key- Base64 after :"+Base64.encode (key.getEncoded()) ); } private static KeyStore createKeyStore(String keyStoreType,File keyStoreFile,String keyStorePassword) throws Exception{ KeyStore keyStore = KeyStore.getInstance(keyStoreType); keyStore.load((InputStream) null, keyStorePassword.toCharArray()); // Write KeyStore to disk final FileOutputStream fileOutputStream = new FileOutputStream(keyStoreFile); try { keyStore.store(fileOutputStream, keyStorePassword.toCharArray()); fileOutputStream.flush(); } finally { fileOutputStream.close(); } return keyStore; } private static KeyStore loadKeyStore(String keyStoreType,File keyStoreFile,String keyStorePassword) throws Exception{ KeyStore keyStore = KeyStore.getInstance(keyStoreType); keyStore.load((InputStream) new FileInputStream(keyStoreFile), keyStorePassword.toCharArray()); return keyStore; } private static void createSecretKeyAndStore(File keyStorefile ,KeyStore keyStore,String keyStorePwd, Key key, String keyAlias ,String keyAccessPassword) throws Exception{ keyStore.setKeyEntry(keyAlias, key, keyAccessPassword.toCharArray(), null); // Write KeyStore to disk final FileOutputStream fileOutputStream = new FileOutputStream(keyStorefile); try { keyStore.store(fileOutputStream, keyStorePwd.toCharArray()); } finally { fileOutputStream.close(); } } private static Key getKeyFromStore(KeyStore keyStore, String keyAlias,String keyAccessPassword) throws Exception { Key keyFromStore = null; keyFromStore = keyStore.getKey(keyAlias, keyAccessPassword.toCharArray()); return keyFromStore; } } </code></pre> <p><strong>Result</strong></p> <pre><code>key- Base64 before:[B@c7e553 key- Base64 after :[B@1ac04e8 </code></pre>

    1. COYou are getting the default Java `Object.toString()` behaviour. Your problem is with Java, not encryption. Try `Arrays.toString(Base64.encode (key.getEncoded()))`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
