+The scrypt key derivation function was originally developed for use in the
+Tarsnap online backup system and is designed to be far more secure against
+hardware brute-force attacks than alternative functions such as PBKDF2 or
+bcrypt.
+
+This simple password-based encryption utility is available as a demonstration
+of the scrypt key derivation function. 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.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
