Constructor Detail

### SSL

    public SSL()

Method Detail

### version

    public static int version()

### versionString

    public static java.lang.String versionString()

### initialize

    public static int initialize(java.lang.String engine)

  Initialize OpenSSL support. This function needs to be called once for the lifetime of JVM. Library.init() has to be called before.

  Parameters:
    `engine` - Support for external a Crypto Device ("engine"), usually a hardware accellerator card for crypto operations.
  Returns:
    APR status code

### randSet

    public static boolean randSet(java.lang.String filename)

  Set source of entropy to use in SSL

  Parameters:
    `filename` - Filename containing random data

### randLoad

    public static boolean randLoad(java.lang.String filename)

  Add content of the file to the PRNG

  Parameters:
    `filename` - Filename containing random data. If null the default file will be tested. The seed file is $RANDFILE if that environment variable is set, $HOME/.rnd otherwise. In case both files are unavailable builtin random seed generator is used.

### randSave

    public static boolean randSave(java.lang.String filename)

  Writes a number of random bytes (currently 1024) to file `filename` which can be used to initialize the PRNG by calling randLoad in a later session.

  Parameters:
    `filename` - Filename to save the data

### randMake

    public static boolean randMake(java.lang.String filename,
                                   int len,
                                   boolean base64)

  Creates random data to filename

  Parameters:
    `filename` - Filename to save the data
    `len` - The length of random sequence in bytes
    `base64` - Output the data in Base64 encoded format

### newBIO

    public static long newBIO(long pool,
                              BIOCallback callback)
                       throws java.lang.Exception

  Initialize new BIO

  Parameters:
    `pool` - The pool to use.
    `callback` - BIOCallback to use
  Returns:
    New BIO handle
  Throws:
    `java.lang.Exception`

### closeBIO

    public static int closeBIO(long bio)

  Close BIO and derefrence callback object

  Parameters:
    `bio` - BIO to close and destroy.
  Returns:
    APR Status code

### setPasswordCallback
