by comparing the computed hash (i.e., the output produced by executing a hashing algorithm) to a known and expected hash value, a person can determine the data&#8217;s integrity. For example, computing the hash of a downloaded file and comparing the result to a previously published hash result can show whether the download has been modified or tampered with. In addition, cryptographic hash functions are extremely collision-resistant; in other words, it should be extremely difficult to produce the same hash output from two different input values using a cryptographic hash function.<\/p>\n\n\n\n<p>Secure Hash Algorithm 2 (SHA-2) is a set of cryptographic hash functions designed by the National Security Agency (NSA). It consists of six identical hashing algorithms (i.e., SHA-256, SHA-512, SHA-224, SHA-384, SHA-512\/224, SHA-512\/256) with a variable digest size. SHA-256 is a <strong>256<\/strong>-bit ( <strong>32 <\/strong>byte) hashing algorithm which can calculate a hash code for an input of up to <strong>264 &#8211; 1 <\/strong>bits. It undergoes <strong>64 <\/strong>rounds of hashing and calculates a hash code that is a <strong>64<\/strong>-digit hexadecimal number. Given a string, <strong>s<\/strong>, print its SHA-256 hash value.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Input_Format\"><\/span><strong>Input Format<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>A single alphanumeric string denoting <strong>s<\/strong>.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Constraints\"><\/span><strong>Constraints<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<ul><li><strong>6 &lt;= |s| &lt;= 20<\/strong><\/li><li>String <strong>s <\/strong>consists of English alphabetic letters (i.e.,<strong>[a-z A-Z]<\/strong> and\/or decimal digits (i.e.,<strong>0<\/strong> through <strong>9<\/strong>) only.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Output_Format\"><\/span><strong>Output Format<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Print the SHA-256 encryption value of <strong>s <\/strong>on a new line.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Sample_Input_0\"><\/span><strong>Sample Input 0<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<pre class=\"wp-block-code\"><code> HelloWorld<\/code><\/pre>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Sample_Output_0\"><\/span><strong>Sample Output 0<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<pre class=\"wp-block-code\"><code> 68e109f0f40ca72a15e05cc22786f8e6<\/code><\/pre>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Sample_Input_1\"><\/span><strong>Sample Input 1<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<pre class=\"wp-block-code\"><code> Javarmi123<\/code><\/pre>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Sample_Output_1\"><\/span><strong>Sample Output 1<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<pre class=\"wp-block-code\"><code> 2da2d1e0ce7b4951a858ed2d547ef485<\/code><\/pre>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Solution_%E2%80%93_Java_SHA-256\"><\/span><strong>Solution &#8211; Java SHA-256<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"java\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">import java.util.*;\nimport java.security.*;\n\npublic class Solution {\n\n    public static void main(String[] args) throws NoSuchAlgorithmException {\n        Scanner input = new Scanner(System.in);\n        MessageDigest m = MessageDigest.getInstance(\"SHA-256\");\n        m.reset();\n        m.update(input.nextLine().getBytes());\n        for (byte i : m.digest()) {\n            System.out.print(String.format(\"%02x\", i));\n        }\n        System.out.println();\n    }\n}<\/pre>\n\n\n\n<script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js\"><\/script>\n<ins class=\"adsbygoogle\"\n     style=\"display:block; text-align:center;\"\n     data-ad-layout=\"in-article\"\n     data-ad-format=\"fluid\"\n     data-ad-client=\"ca-pub-5246141430412355\"\n     data-ad-slot=\"8798433565\"><\/ins>\n<script>\n     (adsbygoogle = window.adsbygoogle || []).push({});\n<\/script>\n\n\n\n<p><strong>Disclaimer: <\/strong>The above Problem ( <strong><em><a href=\"https:\/\/www.hackerrank.com\/challenges\/sha-256\/problem\" target=\"_blank\" data-type=\"URL\" data-id=\"https:\/\/www.hackerrank.com\/challenges\/sha-256\/problem\" rel=\"noreferrer noopener\">Java SHA-256<\/a><\/em><\/strong> ) is generated by <strong>Hacker Rank <\/strong>but the Solution is Provided by <strong>CodingBroz<\/strong>.
