Question

我使用这个js库来处理大整数：http://www.leemon.com/crypto/BigInt.js问题是当我执行某些操作，比如mult（A，powMod（B，e，N））其中A， B，e和N是大整数我得到一个数组而不是一个大整数...然后当我想用这个结果操作时我不能像它是一个大整数那样做。我怎样才能将这个数组转换成一个大整数？

你知道一些拥有powMod和InverMod方法的javascript大整数库吗？

数组是bigInt，它可以使用库中的可用功能进行操作。如果您希望能够以人类可读的格式查看它，请使用bigInt2str函数。

<script>
var A = randBigInt(100,1);
var B = randBigInt(100,1);
var e = randBigInt(100,1);
var N = randBigInt(100,1);
var mult, x;
console.log('A =  ' + A); // A =  4145,12807,14234,10758,3424,5601,901,0
console.log('B =  ' + B); // B =  8476,8451,3441,15572,3002,10012,1000,0
console.log('e =  ' + e); // e =  3792,11382,3645,6320,9155,11401,789,0
console.log('N =  ' + N); // N =  5401,1700,6760,6147,11285,5907,837,0
mult = mult(A, powMod(B, e, N)); // the operation works
console.log('mult =  ' + mult); // mult =  24610,5611,13200,16143,988,8897,7049,13093,30523,11847,495,29557,22316,2,0
x = add(mult,N); // the operation works
console.log('x =  ' + x); // x =  30011,7311,19960,22290,12273,14804,7886,13093,30523,11847,495,29557,22316,2,0

console.log('mult as string, base 10: ' + bigInt2str(mult,10)); // 291979269279106415301425615088143991732473941997421745796392
console.log('x as string, base 10: ' + bigInt2str(x,10));       // 291979269279106415301425615088815343267840898748372641292627
