2003-02-10 Raif S. Naffah <raif@fl.net.au> * java/math/BigInteger.java: Updated notice to include years 2002 and 3. Added 2 private (int) arrays with values from the HAC (Handbook of Applied Cryptography -A. Menezes & al): k[] that contains bit lengths and t[] that contains nbr. of tests --used in isProbablePrime(). * java/math/BigInteger.java (make(long)): Merged into valueOf(long). * java/math/BigInteger.java (make(int[],int), add(int,int), add(BI,BI,int), times(BI,int), divide(long,long,BI,BI,int), gcd(BI), isProbablePrime(int), shift(BI,int), valueOf(String,int), neg(BI), bitOp(int,BI,BI), and(BI,int)): Use valueOf(long) instead of make(long). * java/math/BigInteger.java (euclidInv): Reduce number of work vars (euclidInv(int,int,int)): Now returns an array of 2 ints instead of 3. (euclidInv(BI,BI,BI)): Used to return an array of 2 BIs; now accepts 6 BIs and returns void. (modInverse(BI)): Use new signatures of euclidInv(). * java/math/BigInteger.java (isProbablePrime(int)): Use divide() with static small primes instead of remainder(). Use pre-computed max nbr of trials based on bitlength of BI to test. Use pre-computed small primes for the trial tests instead of random numbers. * java/math/BigInteger.java (isOdd, isMinusOne, pow): Removed. not used. * java/math/BigInteger.java (format(int,StringBuffer)): Removed invoacation of MPN.chars_per_word(). not used. * java/math/BigInteger.java (gcd(int,int)): Declared 'tmp' once as local var and used where needed. * java/math/BigInteger.java (modPow(BI,BI)): Fixed spelling. Combined declaration with initialisation of locals. Removed unused var. * java/math/BigInteger.java: Style changes (pow(int)): Removed 'else' keyword. (toString(int)): idem. (doubleValue()): idem. (bitLength()): idem. (equals(Object)): Use static methods name in same class w/o prepending class name. (doubleValue()): idem. (setNegative(BI)): idem. (negate()): idem. (and(BI,int)): idem. (and(BI)): idem. (gcd(BI)): idem. (byteArrayToIntArray()): Removed casting to (int). this is std. behaviour. (canonicalize()): idem. (alloc(int)): Always instantiate a new BI. From-SVN: r62656
