Returns the key in its primary encoding format, or null if this key does not support encoding.

Usage

From source file:com.github.sshw.crypt.EncryptionBean.java

public String decrypt(String message, String password) throws Exception {
    Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
    Key key = keyFromPassword(password);
    byte[] cb = Base64.decodeBase64(message);
    IvParameterSpec ivb = new IvParameterSpec(key.getEncoded());
    cipher.init(Cipher.DECRYPT_MODE, key, ivb);
    String plaintext = new String(cipher.doFinal(cb));
    return plaintext;
