sencrypt
========

Description
-----------

sencrypt and sdecrypt are utilities for encrypting and decrypting data with the
AES, DES, 3DES, and RC4 algorithms. It can read keys from files or ask for a
passphrase and use that together with a salt to derive a key using the PBKDF2
key derivation function.

sencrypt and sdecrypt are portable and compatible reimplementations of the
encrypt and decrypt utilities in Solaris/Illumos-based operating systems.

Build Instructions
------------------

sencrypt requires a POSIX:2004 compatible operating system, and needs GNU make,
GNU or BSD install, and the OpenSSL library to be installed. It has been tested
on Linux distributions, FreeBSD, Solaris and Illumos-derived distributions,
UnixWare, and OpenServer.
