1 # jsbn: javascript big number 2 3 [Tom Wu's Original Website](http://www-cs-students.stanford.edu/~tjw/jsbn/) 4 5 I felt compelled to put this on github and publish to npm. I haven't tested every other big integer library out there, but the few that I have tested in comparison to this one have not even come close in performance. I am aware of the `bi` module on npm, however it has been modified and I wanted to publish the original without modifications. This is jsbn and jsbn2 from Tom Wu's original website above, with the modular pattern applied to prevent global leaks and to allow for use with node.js on the server side. 6 7 ## usage 8 9 var BigInteger = require('jsbn'); 10 11 var a = new BigInteger('91823918239182398123'); 12 alert(a.bitLength()); // 67 13 14 15 ## API 16 17 ### bi.toString() 18 19 returns the base-10 number as a string 20 21 ### bi.negate() 22 23 returns a new BigInteger equal to the negation of `bi` 24 25 ### bi.abs 26 27 returns new BI of absolute value 28 29 ### bi.compareTo 30 31 32 33 ### bi.bitLength 34 35 36 37 ### bi.mod 38 39 40 41 ### bi.modPowInt 42 43 44 45 ### bi.clone 46 47 48 49 ### bi.intValue 50 51 52 53 ### bi.byteValue 54 55 56 57 ### bi.shortValue 58 59 60 61 ### bi.signum 62 63 64 65 ### bi.toByteArray 66 67 68 69 ### bi.equals 70 71 72 73 ### bi.min 74 75 76 77 ### bi.max 78 79 80 81 ### bi.and 82 83 84 85 ### bi.or 86 87 88 89 ### bi.xor 90 91 92 93 ### bi.andNot 94 95 96 97 ### bi.not 98 99 100 101 ### bi.shiftLeft 102 103 104 105 ### bi.shiftRight 106 107 108 109 ### bi.getLowestSetBit 110 111 112 113 ### bi.bitCount 114 115 116 117 ### bi.testBit 118 119 120 121 ### bi.setBit 122 123 124 125 ### bi.clearBit 126 127 128 129 ### bi.flipBit 130 131 132 133 ### bi.add 134 135 136 137 ### bi.subtract 138 139 140 141 ### bi.multiply 142 143 144 145 ### bi.divide 146 147 148 149 ### bi.remainder 150 151 152 153 ### bi.divideAndRemainder 154 155 156 157 ### bi.modPow 158 159 160 161 ### bi.modInverse 162 163 164 165 ### bi.pow 166 167 168 169 ### bi.gcd 170 171 172 173 ### bi.isProbablePrime 174 175
