javascript - How to find a SHA1 encrypted string from the 5-word encrypted hash in Ruby? -


say you're encrypting string "alextoul" cryptojs.sha1.

as explained in source below object looks that:

cryptojs.sha1("alextoul") = {words: { 0: 1025575641 1: -2026381578 2: 1077518901 3: 1028391820 4: 1049226021 }}

turns out if convert string get:

cryptojs.sha1("alextoul").tostring() = "3d210ad98737def64039a2353d4c038c3e89eb25"

now i'm trying find string above ("3d210ad98737def64039a2353d4c038c3e89eb25") 5 words in ruby.

thefunctionineed(params[:words]) # equal "3d210ad98737def64039a2353d4c038c3e89eb25"

just reading source:

https://code.google.com/p/crypto-js/source/browse/tags/3.1.2/src/core.js#181 -->

https://code.google.com/p/crypto-js/source/browse/tags/3.1.2/src/core.js#306 -->

function stringify(wordarray) {         // shortcuts         var words = wordarray.words;         var sigbytes = wordarray.sigbytes;          // convert         var hexchars = [];         (var = 0; < sigbytes; i++) {             var bite = (words[i >>> 2] >>> (24 - (i % 4) * 8)) & 0xff;             hexchars.push((bite >>> 4).tostring(16));             hexchars.push((bite & 0x0f).tostring(16));         }          return hexchars.join('');     } 

then call

stringify(cryptojs.sha1("alextoul")) 

sorry don't know ruby enough port that
