Method Detail

addToSNIServerNameList

public static java.util.List<javax.net.ssl.SNIServerName> addToSNIServerNameList(java.util.List<javax.net.ssl.SNIServerName> serverNames,
                                                                                 java.lang.String hostname)

Puts hostname into the serverNames list.

If the serverNames does not look like a legal FQDN, it will not be put into the returned list.

Note that the returned list does not allow duplicated name type.

Returns:

a list of SNIServerName

getBooleanProperty

public static boolean getBooleanProperty(java.lang.String propName,
                                         boolean defaultValue)

Return the value of the boolean System property propName. Note use of privileged action. Do NOT make accessible to applications.

indent

public static java.lang.String indent(java.lang.String source)

indent

public static java.lang.String indent(java.lang.String source,
                                      java.lang.String prefix)

byte16HexString

public static java.lang.String byte16HexString(int id)

toHexString

public static java.lang.String toHexString(byte[] bytes)

toHexString

public static java.lang.String toHexString(long lv)

toByteArray

public static byte[] toByteArray(java.math.BigInteger bi)

Utility method to convert a BigInteger to a byte array in unsigned format as needed in the handshake messages. BigInteger uses 2's complement format, i.e. it prepends an extra zero if the MSB is set. We remove that.

reverseBytes

public static void reverseBytes(byte[] arr)

privilegedGetProperty

public static java.lang.String privilegedGetProperty(java.lang.String theProp,
                                                     java.lang.String defaultVal)

privilegedGetBooleanProperty

public static boolean privilegedGetBooleanProperty(java.lang.String theProp)

privilegedGetIntegerProperty

public static java.lang.Integer privilegedGetIntegerProperty(java.lang.String theProp,
                                                             int defaultValue)

privilegedGetIntegerProperty

public static java.lang.Integer privilegedGetIntegerProperty(java.lang.String theProp)
