    copied!<p>I'm quite new to NodeJs and trying to figure out how to use the "crypto" module. While playing around with it I notice the difference between the "crypto" module in NodeJs and crypto-js: </p> <p>With crypto-js, I have: </p> <pre><code>function SHA256Hash(password, salt, iteration) { var saltedpassword = salt + password; var sha256 = CryptoJS.algo.SHA256.create(); for(var i = 0; i &lt; iteration; i++) { alert("saltedpassword = " + saltedpassword); sha256.update(saltedpassword); var saltedpassword = sha256.finalize(); sha256.reset(); } return saltedpassword.toString(CryptoJS.enc.Base64); } </code></pre> <p>Then call : </p> <pre><code>var hashedPassword = SHA256Hash("123456789", "ASIN", 3) </code></pre> <p>And receive : </p> <pre><code>saltedpassword = ASIN123456789 saltedpassword = 3362d80b757d14bfe18c01f6a003ed38a3a4a3dcab0417efb457b71740e21411 saltedpassword = 6020c992a9b7cd3ca9e95b9a3e21b64911edb7983b3dd77bdcecda19f2756987 </code></pre> <p>With "crypto" module, I wrote: </p> <pre><code>function SHA256Hash(password, salt, iteration) { var saltedpassword = salt + password; for(var i = 0; i &lt; iteration-1; i++) { console.log("saltedpassword = "+saltedpassword) var sha256 = crypto.createHash('sha256'); sha256.update(saltedpassword); var saltedpassword = sha256.digest('hex'); } console.log("saltedpassword = "+saltedpassword) var sha256 = crypto.createHash('sha256'); sha256.update(saltedpassword); return sha256.digest('base64'); } </code></pre> <p>Then call: </p> <pre><code>var hashedPassword = SHA256Hash("123456789", "ASIN", 3); </code></pre> <p>And receive:</p> <pre><code>saltedpassword = ASIN123456789 saltedpassword = 3362d80b757d14bfe18c01f6a003ed38a3a4a3dcab0417efb457b71740e21411 saltedpassword = 4795d40ae8ae797f0ce51dfe4b496bca68f6d1f4a264f4ca52348ddd65a2988d </code></pre> <p>The first two items are the same but the third item is different. Did I miss out something ?</p> <p><strong>Edited</strong>: As I compare to the Jasypt, CryptoJs generates similar keys. My question is how to tune "crypto" module to make it generate the same keys as CryptoJS and Jasypt do. </p>
