Hi Cedric/Yehuda, I have generated the signature dynamically as like in this documentation http://s3.amazonaws.com/doc/s3-developer-guide/RESTAuthentication.html
by using a reference http://birkoff.net/blog/amazon-s3-query-string-authentication-using-php/ and my code is like ------------------------------------------------------------------------ $aws_access_key_id = 'KGXJJGKDM5G7G4CNKC7R'; $aws_secret_key = 'LC7S0twZdhtXA1XxthfMDsj5TgJpeKhZrloWa9WN'; $downloadAudioTimeout = '+20 minutes'; $file_path = "usage"; $http_verb = "GET"; $content_md5 = ""; $content_type = ""; $expires = strtotime($downloadAudioTimeout); $canonicalizedAmzHeaders = ""; $canonicalizedResource = '/usage';; $stringToSign = $http_verb . "\n" . $content_md5 . "\n" . $content_type . "\n" . $expires . "\n" . $canonicalizedAmzHeaders . $canonicalizedResource; $signature = urlencode(hex2b64(hmacsha1($aws_secret_key, utf8_encode($stringToSign)))); echo "url=".$url = " http://gateway.3linux.com/$file_path?AWSAccessKeyId=$aws_access_key_id&Signature=$signature&Expires=$expires "; return $url; function hmacsha1($key,$data) { $blocksize=64; $hashfunc='sha1'; if (strlen($key)>$blocksize) $key=pack('H*', $hashfunc($key)); $key=str_pad($key,$blocksize,chr(0x00)); $ipad=str_repeat(chr(0x36),$blocksize); $opad=str_repeat(chr(0x5c),$blocksize); $hmac = pack( 'H*',$hashfunc( ($key^$opad).pack( 'H*',$hashfunc( ($key^$ipad).$data ) ) ) ); return bin2hex($hmac); } /* * Used to encode a field for Amazon Auth * (taken from the Amazon S3 PHP example library) */ function hex2b64($str) { $raw = ''; for ($i=0; $i < strlen($str); $i+=2) { $raw .= chr(hexdec(substr($str, $i, 2))); } return base64_encode($raw); } -------------------------------------------------------------- I got the url like http://gateway.3linux.com//admin/usage?AWSAccessKeyId=KGXJJGKDM5G7G4CNKC7R&Signature=ivLXdG9TltSTYEGc5nf%2B5%2B2lyxs%3D&Expires=1398757716<http://gateway.3linux.com/admin/usage?AWSAccessKeyId=KGXJJGKDM5G7G4CNKC7R&Signature=ivLXdG9TltSTYEGc5nf%2B5%2B2lyxs%3D&Expires=1398757716> by using the above. When i enter this on the browser, i got the same access denied error. Could you please check if there is any issues with this ?
