SHA1 hash differences between node.js and PHP

Question

I would like to convert this piece of node.js code to PHP code. (WORKING)

function generateHashedPass (password, salt) { var byteSalt = new Buffer(salt, 'base64'); var bytePass = new Buffer(password, 'ucs2'); var byteResult = Buffer.concat([byteSalt, bytePass]); return sha1.update(byteResult).digest('base64'); } console.log(generateHashedPass('111111', 'UY68RQZT14QPgSsfaw/F+w==') === 'L0xc787MxCwJJaZjFX6MqxkVcFE=' ? "Algo correct" : "Algo wrong" ); 

Now I have something similar in php: (DOES NOT WORK)

 public function getHashedPass($pass, $salt) { $base_salt = unpack('H*', base64_decode($salt)); $base_pass = unpack('H*', mb_convert_encoding($pass, 'UCS-2', 'auto')); $base_result = $base_salt[1] . $base_pass[1]; return base64_encode(sha1($base_result)); } 

But the result does not match the node.js. function

The result should be as follows: L0xc787MxCwJJaZjFX6MqxkVcFE =

When is the password: 111111

And there is salt: UY68RQZT14QPgSsfaw / F + w ==

Try the following:

 //---------------------------------------------------- function getCharHex($aString) { $bytes = str_split($aString, 2); $result = ""; foreach ($bytes as $byte) { $result .= chr(hexdec($byte)); } return $result; } //---------------------------------------------------- function getHashedPass($pass, $salt) { $base_salt = unpack('H*', base64_decode($salt)); $base_pass = unpack('H*', mb_convert_encoding($pass, 'UCS-2LE', 'auto')); $base_result = getCharHex($base_salt[1].$base_pass[1]); return base64_encode(sha1($base_result, true)); } echo getHashedPass('111111', 'UY68RQZT14QPgSsfaw/F+w=='); //L0xc787MxCwJJaZjFX6MqxkVcFE=
