NIST Misses 2024 Deadline to Clear NVD Backlog
NIST has failed to meet its self-imposed deadline of clearing the NVD's backlog by the end of the fiscal year. Meanwhile, CVE's awaiting analysis have increased by 33% since June.
big-integer
The big-integer npm package is designed for arithmetic and logical operations on large integers beyond the safe limit for JavaScript's native number type. It provides a way to work with integers of arbitrary size, allowing for precise calculations that would otherwise be impossible due to the limitations of standard number precision in JavaScript.
Arithmetic Operations
Demonstrates basic arithmetic operations such as addition, subtraction, multiplication, division, and modulo on large integers.
"use strict";\nconst bigInt = require('big-integer');\nlet x = bigInt('123456789012345678901234567890');\nlet y = bigInt('98765432109876543210987654321');\nlet sum = x.add(y);\nlet difference = x.minus(y);\nlet product = x.multiply(y);\nlet quotient = x.divide(y);\nlet remainder = x.mod(y);\nconsole.log('Sum:', sum.toString());\nconsole.log('Difference:', difference.toString());\nconsole.log('Product:', product.toString());\nconsole.log('Quotient:', quotient.toString());\nconsole.log('Remainder:', remainder.toString());
Logical Operations
Shows how to perform bitwise logical operations such as AND, OR, and XOR on large integers.
"use strict";\nconst bigInt = require('big-integer');\nlet x = bigInt('12345678901234567890');\nlet y = bigInt('9876543210987654321');\nlet andResult = x.and(y);\nlet orResult = x.or(y);\nlet xorResult = x.xor(y);\nconsole.log('AND:', andResult.toString());\nconsole.log('OR:', orResult.toString());\nconsole.log('XOR:', xorResult.toString());
Comparison Operations
Illustrates how to compare two large integers, checking for greater than, less than, and equality.
"use strict";\nconst bigInt = require('big-integer');\nlet x = bigInt('12345678901234567890');\nlet y = bigInt('9876543210987654321');\nconsole.log('x > y:', x.greater(y));\nconsole.log('x < y:', x.lesser(y));\nconsole.log('x == y:', x.equals(y));
bignumber.js is a well-known library for arbitrary-precision decimal and non-decimal arithmetic. It's similar to big-integer but also supports decimal numbers, making it more versatile for applications requiring floating-point calculations.
decimal.js is another library for arbitrary-precision arithmetic, focusing on decimal numbers. It offers a similar range of operations as big-integer but is optimized for decimal arithmetic, providing high precision for financial and scientific calculations.
jsbn is a library that implements big-integer arithmetic in pure JavaScript. It's similar to big-integer in its focus on large integers but is known for its use in cryptographic applications and for being part of the jsencrypt library.
