On modern hardware and with default +parameters, the cost of cracking the password on a file encrypted by scrypt +enc is approximately 100 billion times more than the cost of cracking the same +password on a file encrypted by openssl enc; this means that a five-character +password using scrypt is stronger than a ten-character password using openssl. diff --git a/system/scrypt/scrypt.SlackBuild b/system/scrypt/scrypt.SlackBuild new file mode 100644 index 0000000000000..397be1abb56a1 --- /dev/null +++ b/system/scrypt/scrypt.SlackBuild @@ -0,0 +1,95 @@ +#!/bin/sh + +# Copyright (c) 2011-2013 LEVAI Daniel +# All rights reserved. +# +# * Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions +# are met: +# * Redistributions of source code must retain the above copyright notice +# this list of conditions and the following disclaimer. +# * Redistributions in binary form must reproduce the above copyright +# notice, this list of conditions and the following disclaimer in the +# documentation and/or other materials provided with the distribution. +# +# THIS SOFTWARE IS PROVIDED ''AS IS'' AND ANY EXPRESS OR IMPLIED WARRANTIES, +# INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY +# AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.
