Variables

o DEBUG 
 public static boolean DEBUG

Constructors

o DSigUtil 
 public DSigUtil()

Methods

o waitKey 
 public static void waitKey()
Wait for user to press a key

o bigIntegerToBase64 
 public static String bigIntegerToBase64(BigInteger bi)
Encode a BigInteger in Base 64 encoding. Included here as signature suite implementations will frequently need it.

o base64ToBigInteger 
 public static BigInteger base64ToBigInteger(String b64)
Decode a Base 64 encoded BigInteger. Return the BigInteger object or null if the input was not properly encoded. Included here as signature suite implementations will frequently need it.

o byteArrayToBase64 
 public static String byteArrayToBase64(byte bytes[])
o base64ToByteArray 
 public static byte[] base64ToByteArray(String s) throws DSigException
Returns a byte array representatino of a base64 string.

Throws: DSigException
if the String is a valid base64 String.
o dictionaryToVector 
 public static Vector dictionaryToVector(Dictionary dict)
Returns a vector form of a dictionary

o readln 
 public static String readln(String msg,
                             String def)
Reads a string from the user. msg is the question displayed to the user, and def if the default answer if the user simply press return key.

o toString 
 public static String toString(Object exp)
Produces a string representation of an s-expression.

o printHexDump 
 public static void printHexDump(byte data[])
Print a hexdump of the given byte array. Remainder from debugging.
