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.
The current development version is available from its source code repository.

- Add manpage
- Initial revision
sencrypt requires a POSIX:2004 compatible operating system, it has been tested to work on Linux distributions, FreeBSD, Solaris and Illumos-derived distributions, UnixWare, and OpenServer. The following tools and shared libraries are required to build sencrypt:
- GNU make >= 3.81
- GNU or BSD install
Rebuilding the man pages additionally requires the xsltproc tool from libxml2.
Before building sencrypt check the commented macros in the Makefile for any macros you may need to override depending on the used toolchain and operating system.
By default, all files will be installed under the "/usr/local" directory, a
different installation path prefix can be set via the
prefix macro. In
addition, a second path prefix can be specified via the
DESTDIR macro which
will be prepended to any path, incuding the
prefix macro path prefix. In
prefix, the path specified via the
DESTDIR macro will only be
prepended to paths during installation and not be used for constructing
The following instructions assume that
make is GNU make, on some platforms
it may be installed under a different name or a non-default path. In order to
start the build process run
make all. After a successful build, run
install to install the program, any associated data files and the
Previously built binaries, object files, generated data files and
documentation can be removed by running
make clean, any additional,
generated files which are not removed by the
clean target can be removed by
Please send any feedback, translations or bug reports via email to email@example.com.
When sending bug reports, please always mention the exact version of sencrypt with which the issue occurs as well as the version of the operating system you are using and make sure that you provide sufficient information to reproduce the issue and include any input, output, any error messages.
In case of build issues, please also specify the implementations and versions of the tools and shared libraries used to build the program, in particular the compiler.
In case of crashes, please generate a stack trace with a suitable debugger such as gdb, lldb, dbx, or debug after a crash has occurred either by examining the resulting core file or by running the program from the debugger and attach it to the bug report. In order to generate a meaningful stack trace the program as well as any dynamically linked libraries need to be built with debugging information, see the documentation of the used compiler for the required compiler flags. If any of the dynamically linked shared libraries do not contain debugging information, please either install debugging information for these libraries using mechanisms provided by your operating system or rebuild the libraries accordingly. Please refer to the documentation of the debugger for detailed instructions on generating backtraces.
