Encryptor (LicenseManager - Core 1.1.0 API Documentation)

```
public final class Encryptor
extends Object
```
A class for easy, strong, two-way encryption/decryption of strings. Versions prior to 0.9.1-beta used 256-bit AES encryption, which is not exportable, and will only work by default on Mac OS X and Linux. The Windows JVM will throw an exception without the JCE Unlimited Strength policy file. Versions 0.9.1-beta and higher use 128-bit AES encryption that is both exportable and platform-independent.

This encryptor still uses a combination of MD5+DES and SHA-1+AES encryption.

Data encrypted with this class prior to version 0.9.1-beta cannot be decrypted anymore.

Since:

1.0.0

Version:

1.5.0

    Encrypt the plain-text string using the default passphrase. For encrypting, the data will first be padded to a safe number of bytes with randomized data.
    
    Parameters:
    unencrypted - The plain-text string to encrypt
    
    Returns:
    the encrypted string Base64-encoded.
    See Also:
    pad(byte[], int)
  - encrypt
```
public static String encrypt(String unencrypted,
             char[] passphrase)
```
    Encrypt the plain-text string. For encrypting, the string will first be padded to a safe number of characters with randomized data.
    
    Parameters:
    unencrypted - The plain-text string to encrypt
    passphrase - The passphrase to encrypt the data with
    
    Returns:
    the encrypted string Base64-encoded.
  - encrypt
```

    Parameters:
    unencrypted - The binary data to encrypt
    passphrase - The passphrase to encrypt the data with
    
    Returns:
    the encrypted string Base64-encoded.
    See Also:

```
public static byte[] encryptRaw(byte[] unencrypted)
```
    Encrypt the binary data using the default passphrase. For encrypting, the data will first be padded to a safe number of bytes with randomized data.
    
    Parameters:
    unencrypted - The binary data to encrypt
    
    Returns:
    the encrypted data.
    See Also:
    pad(byte[], int)
  - encryptRaw
```
public static byte[] encryptRaw(byte[] unencrypted,
                char[] passphrase)
```
    Encrypt the binary data. For encrypting, the data will first be padded to a safe number of bytes with randomized data.
    
    Parameters:
    unencrypted - The binary data to encrypt
    passphrase - The passphrase to encrypt the data with
    
    Returns:
    the encrypted data.
    See Also:

  - decrypt
```
public static String decrypt(String encrypted)
```
    Decrypt an encrypted string using the default passphrase. Any padded data will be removed from the string prior to its return.
    
    Parameters:
