argon2rs
========
[![Build
Status](https://travis-ci.org/bryant/argon2rs.svg?branch=master)](https://travis-ci.org/bryant/argon2rs)
This is a purely Rust-based library that provides both variants of the
state-of-the-art Argon2 hashing algorithm, suitable for password hashing and
password-based key derivation.
[Documentation](http://bryant.github.io/argon2rs/argon2rs/)
## Installation
Via cargo:
```bash
$ cd $PROJECT_ROOT
$ cargo install --features "simd"
```
From git:
```bash
$ git clone https://github.com/bryant/argon2rs $ARGON_DIR && cd $ARGON_DIR
$ cargo build --features "simd"
```
## Usage
From `examples/helloworld.rs`:
```rust
extern crate argon2rs;
pub fn main() {
let (password, salt) = ("argon2i!", "delicious salt");
println!("argon2i(\"argon2i\", \"delicious\"):");
for byte in argon2rs::simple2i(&password, &salt).iter() {
print!("{:02x}", byte);
}
println!("");
}
```
outputs:
```
argon2i("argon2i", "delicious"):
e254b28d820f26706a19309f1888cefd5d48d91384f35dc2e3fe75c3a8f665a6
```
There are two variants of Argon2 that differ in the manner by which reference
indices are computed during block-filling rounds. Argon2d does this in a faster
but data-dependent fashion that could be vulnerable to side-channel
[attacks][1], whereas Argon2i ("i" denoting independence from plaintext input)
works slower but is immune to such attacks and is therefore the preferred choice
for password hashing.
## TODO
- [x] Parallelize.
- [x] Incorporate SIMD into compression function.
- [x] Zero-on-drop trait for sensitive(s): `Matrix`
- [x] Constant-time verification API.
- [x] Benchmarks.
- [ ] Support NEON and SIMD on other arches.
- [ ] Fuzz.
## LICENSE
MIT.
## Benchmarks
Our primary benchmarks are single- and multi-threaded runs of Argon2i with
default parameters against the [reference implementation][2]. In order to
compile and run this, first pull in the C sources:
```bash
$ git submodule init
$ git submodule update benches/cargon/phc-winner-argon2
```
and then benchmark with Cargo as usual:
```
$ rustc --version
rustc 1.11.0-dev (4b240fe96 2016-06-08)
$ export RUSTFLAGS='-C target-feature=+avx'
$ cargo bench --features=simd

by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.

that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.

the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

# libbacktrace
A C library that may be linked into a C/C++ program to produce symbolic backtraces
Initially written by Ian Lance Taylor <iant@golang.org>.
This is version 1.0.
It is likely that this will always be version 1.0.
The libbacktrace library may be linked into a program or library and
used to produce symbolic backtraces.
Sample uses would be to print a detailed backtrace when an error
occurs or to gather detailed profiling information.
The libbacktrace library is provided under a BSD license.
See the source files for the exact license text.
The public functions are declared and documented in the header file
backtrace.h, which should be #include'd by a user of the library.
Building libbacktrace will generate a file backtrace-supported.h,
which a user of the library may use to determine whether backtraces
will work.
See the source file backtrace-supported.h.in for the macros that it
defines.
As of January 2018, libbacktrace only supports ELF, PE/COFF, and XCOFF
executables with DWARF debugging information.
The library is written to make it straightforward to add support for
other object file and debugging formats.
The library relies on the C++ unwind API defined at
https://itanium-cxx-abi.github.io/cxx-abi/abi-eh.html
This API is provided by GCC.

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

# serial 4 lt~obsolete.m4
# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.

copyright notice that is included in or attached to the work
(an example is provided in the Appendix below).
"Derivative Works" shall mean any work, whether in Source or Object
form, that is based on (or derived from) the Work and for which the
editorial revisions, annotations, elaborations, or other modifications

of this License, Derivative Works shall not include works that remain
separable from, or merely link (or bind by name) to the interfaces of,
the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner
or by an individual or Legal Entity authorized to submit on behalf of
the copyright owner. For the purposes of this definition, "submitted"
means any form of electronic, verbal, or written communication sent

copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the

3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained

pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.

WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the

whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

# backtrace-rs
[![Build Status](https://travis-ci.org/alexcrichton/backtrace-rs.svg?branch=master)](https://travis-ci.org/alexcrichton/backtrace-rs)
[![Build status](https://ci.appveyor.com/api/projects/status/v4l9oj4aqbbgyx44?svg=true)](https://ci.appveyor.com/project/alexcrichton/backtrace-rs)
[Documentation](https://docs.rs/backtrace)
A library for acquiring backtraces at runtime for Rust. This library aims to
enhance the support given by the standard library at `std::rt` by providing a
more stable and programmatic interface.
## Install
```toml
[dependencies]
backtrace = "0.3"
```
```rust
extern crate backtrace;
```
Note that this crate requires `make`, `objcopy`, and `ar` to be present on Linux
systems.
## Usage
To simply capture a backtrace and defer dealing with it until a later time,
you can use the top-level `Backtrace` type.
```rust
extern crate backtrace;
use backtrace::Backtrace;
fn main() {
let bt = Backtrace::new();
// do_some_work();
println!("{:?}", bt);
}
```
If, however, you'd like more raw access to the actual tracing functionality, you
can use the `trace` and `resolve` functions directly.
```rust
extern crate backtrace;
fn main() {
backtrace::trace(|frame| {
let ip = frame.ip();
let symbol_address = frame.symbol_address();
// Resolve this instruction pointer to a symbol name
backtrace::resolve(ip, |symbol| {
if let Some(name) = symbol.name() {
// ...
}
if let Some(filename) = symbol.filename() {
// ...
}
});
true // keep going to the next frame
});
}
```
## Platform Support
This library currently supports OSX, Linux, and Windows. Support for other
platforms is always welcome!
