Clock is a small library for mocking time in Go. It provides an interface
around the standard library's [`time`][time] package so that the application
can use the realtime clock while tests can use the mock clock.
[time]: http://golang.org/pkg/time/
The module is currently maintained by @djmitche.

[![Build Status](https://github.com/btcsuite/btcd/workflows/Build%20and%20Test/badge.svg)](https://github.com/btcsuite/btcd/actions)

[![GoDoc](https://pkg.go.dev/github.com/btcsuite/btcd/btcec/v2?status.png)](https://pkg.go.dev/github.com/btcsuite/btcd/btcec/v2)
Package btcec implements elliptic curve cryptography needed for working with
Bitcoin (secp256k1 only for now). It is designed so that it may be used with the
standard crypto/ecdsa packages provided with go. A comprehensive suite of test
is provided to ensure proper functionality. Package btcec was originally based
on work from ThePiachu which is licensed under the same terms as Go, but it has
signficantly diverged since then. The btcsuite developers original is licensed
under the liberal ISC license.
Although this package was primarily written for btcd, it has intentionally been
designed so it can be used as a standalone package for any projects needing to
use secp256k1 elliptic curve cryptography.
## Installation and Updating
```bash
$ go install -u -v github.com/btcsuite/btcd/btcec/v2
```
## Examples
* [Sign Message](https://pkg.go.dev/github.com/btcsuite/btcd/btcec/v2#example-package--SignMessage)
Demonstrates signing a message with a secp256k1 private key that is first
parsed form raw bytes and serializing the generated signature.
* [Verify Signature](https://pkg.go.dev/github.com/btcsuite/btcd/btcec/v2#example-package--VerifySignature)
Demonstrates verifying a secp256k1 signature against a public key that is
first parsed from raw bytes. The signature is also parsed from raw bytes.
## License
Package btcec is licensed under the [copyfree](http://copyfree.org) ISC License
except for btcec.go and btcec_test.go which is under the same license as Go.

Package btcec implements support for the elliptic curves needed for bitcoin.
Bitcoin uses elliptic curve cryptography using koblitz curves
(specifically secp256k1) for cryptographic functions. See
http://www.secg.org/collateral/sec2_final.pdf for details on the
standard.
This package provides the data structures and functions implementing the
crypto/elliptic Curve interface in order to permit using these curves
with the standard crypto/ecdsa package provided with go. Helper
functionality is provided to parse signatures and public keys from
standard formats. It was designed for use with btcd, but should be
general enough for other uses of elliptic curve crypto. It was originally based
on some initial work by ThePiachu, but has significantly diverged since then.

// ensure all state and input is valid for most code, this is a bit of an
// exception because those extra checks really add up in what ends up being
// critical hot paths.
//
// The first key concept when working with this type is normalization. In order
// to avoid the need to propagate a ton of carries, the internal representation
// provides additional overflow bits for each word of the overall 256-bit
// value. This means that there are multiple internal representations for the
// same value and, as a result, any methods that rely on comparison of the
// value, such as equality and oddness determination, require the caller to
// provide a normalized value.
//
// The second key concept when working with this type is magnitude. As
// previously mentioned, the internal representation provides additional
// overflow bits which means that the more math operations that are performed
// on the field value between normalizations, the more those overflow bits
// accumulate. The magnitude is effectively that maximum possible number of
// those overflow bits that could possibly be required as a result of a given
// operation. Since there are only a limited number of overflow bits available,
// this implies that the max possible magnitude MUST be tracked by the caller
// and the caller MUST normalize the field value if a given operation would
// cause the magnitude of the result to exceed the max allowed value.
//
// IMPORTANT: The max allowed magnitude of a field value is 64.

secp256k1
=========
[![Build Status](https://github.com/decred/dcrd/workflows/Build%20and%20Test/badge.svg)](https://github.com/decred/dcrd/actions)
[![ISC License](https://img.shields.io/badge/license-ISC-blue.svg)](http://copyfree.org)
[![Doc](https://img.shields.io/badge/doc-reference-blue.svg)](https://pkg.go.dev/github.com/decred/dcrd/dcrec/secp256k1/v4)
Package secp256k1 implements optimized secp256k1 elliptic curve operations.
This package provides an optimized pure Go implementation of elliptic curve
cryptography operations over the secp256k1 curve as well as data structures and
functions for working with public and private secp256k1 keys. See
https://www.secg.org/sec2-v2.pdf for details on the standard.
In addition, sub packages are provided to produce, verify, parse, and serialize
ECDSA signatures and EC-Schnorr-DCRv0 (a custom Schnorr-based signature scheme
specific to Decred) signatures. See the README.md files in the relevant sub
packages for more details about those aspects.
An overview of the features provided by this package are as follows:
- Private key generation, serialization, and parsing
- Public key generation, serialization and parsing per ANSI X9.62-1998
- Parses uncompressed, compressed, and hybrid public keys
- Serializes uncompressed and compressed public keys
- Specialized types for performing optimized and constant time field operations
- `FieldVal` type for working modulo the secp256k1 field prime
- `ModNScalar` type for working modulo the secp256k1 group order
- Elliptic curve operations in Jacobian projective coordinates
- Point addition
- Point doubling
- Scalar multiplication with an arbitrary point
- Scalar multiplication with the base point (group generator)
- Point decompression from a given x coordinate
- Nonce generation via RFC6979 with support for extra data and version
information that can be used to prevent nonce reuse between signing algorithms
It also provides an implementation of the Go standard library `crypto/elliptic`
`Curve` interface via the `S256` function so that it may be used with other
packages in the standard library such as `crypto/tls`, `crypto/x509`, and
`crypto/ecdsa`. However, in the case of ECDSA, it is highly recommended to use
the `ecdsa` sub package of this package instead since it is optimized
specifically for secp256k1 and is significantly faster as a result.
Although this package was primarily written for dcrd, it has intentionally been
designed so it can be used as a standalone package for any projects needing to
use optimized secp256k1 elliptic curve cryptography.
Finally, a comprehensive suite of tests is provided to provide a high level of
quality assurance.
## secp256k1 use in Decred
At the time of this writing, the primary public key cryptography in widespread
use on the Decred network used to secure coins is based on elliptic curves
defined by the secp256k1 domain parameters.
## Installation and Updating
This package is part of the `github.com/decred/dcrd/dcrec/secp256k1/v4` module.
Use the standard go tooling for working with modules to incorporate it.
## Examples
* [Encryption](https://pkg.go.dev/github.com/decred/dcrd/dcrec/secp256k1/v4#example-package-EncryptDecryptMessage)
Demonstrates encrypting and decrypting a message using a shared key derived
through ECDHE.

Package secp256k1 implements optimized secp256k1 elliptic curve operations.
This package provides an optimized pure Go implementation of elliptic curve
cryptography operations over the secp256k1 curve as well as data structures and
functions for working with public and private secp256k1 keys. See
https://www.secg.org/sec2-v2.pdf for details on the standard.
In addition, sub packages are provided to produce, verify, parse, and serialize
ECDSA signatures and EC-Schnorr-DCRv0 (a custom Schnorr-based signature scheme
specific to Decred) signatures. See the README.md files in the relevant sub
packages for more details about those aspects.
An overview of the features provided by this package are as follows:
- Private key generation, serialization, and parsing
- Public key generation, serialization and parsing per ANSI X9.62-1998
- Parses uncompressed, compressed, and hybrid public keys
- Serializes uncompressed and compressed public keys
- Specialized types for performing optimized and constant time field operations
- FieldVal type for working modulo the secp256k1 field prime
- ModNScalar type for working modulo the secp256k1 group order
- Elliptic curve operations in Jacobian projective coordinates
- Point addition
- Point doubling
- Scalar multiplication with an arbitrary point
- Scalar multiplication with the base point (group generator)
- Point decompression from a given x coordinate
- Nonce generation via RFC6979 with support for extra data and version
information that can be used to prevent nonce reuse between signing
algorithms
It also provides an implementation of the Go standard library crypto/elliptic
Curve interface via the S256 function so that it may be used with other packages
in the standard library such as crypto/tls, crypto/x509, and crypto/ecdsa.
However, in the case of ECDSA, it is highly recommended to use the ecdsa sub
package of this package instead since it is optimized specifically for secp256k1
and is significantly faster as a result.
Although this package was primarily written for dcrd, it has intentionally been
designed so it can be used as a standalone package for any projects needing to
use optimized secp256k1 elliptic curve cryptography.
Finally, a comprehensive suite of tests is provided to provide a high level of
quality assurance.
Use of secp256k1 in Decred
At the time of this writing, the primary public key cryptography in widespread
use on the Decred network used to secure coins is based on elliptic curves
defined by the secp256k1 domain parameters.

[![Build Status](https://github.com/decred/dcrd/workflows/Build%20and%20Test/badge.svg)](https://github.com/decred/dcrd/actions)
[![ISC License](https://img.shields.io/badge/license-ISC-blue.svg)](http://copyfree.org)
[![GoDoc](https://img.shields.io/badge/godoc-reference-blue.svg)](https://pkg.go.dev/github.com/decred/dcrd/dcrec/secp256k1/v4/ecdsa)
Package ecdsa provides secp256k1-optimized ECDSA signing and verification.
This package provides data structures and functions necessary to produce and
verify deterministic canonical signatures in accordance with RFC6979 and
BIP0062, optimized specifically for the secp256k1 curve using the Elliptic Curve
Digital Signature Algorithm (ECDSA), as defined in FIPS 186-3. See
https://www.secg.org/sec2-v2.pdf for details on the secp256k1 standard.
It also provides functions to parse and serialize the ECDSA signatures with the
more strict Distinguished Encoding Rules (DER) of ISO/IEC 8825-1 and some
additional restrictions specific to secp256k1.
In addition, it supports a custom "compact" signature format which allows
efficient recovery of the public key from a given valid signature and message
hash combination.
A comprehensive suite of tests is provided to ensure proper functionality.
## ECDSA use in Decred
At the time of this writing, ECDSA signatures are heavily used for proving coin
ownership in Decred as the vast majority of transactions consist of what is
effectively transferring ownership of coins to a public key associated with a
private key only known to the recipient of the coins along with an encumbrance
that requires an ECDSA signature that proves the new owner possesses the private
key without actually revealing it.
## Installation and Updating
This package is part of the `github.com/decred/dcrd/dcrec/secp256k1/v4` module.
Use the standard go tooling for working with modules to incorporate it.
## Examples
* [Sign Message](https://pkg.go.dev/github.com/decred/dcrd/dcrec/secp256k1/v4/ecdsa#example-package-SignMessage)
Demonstrates signing a message with a secp256k1 private key that is first
parsed from raw bytes and serializing the generated signature.
* [Verify Signature](https://pkg.go.dev/github.com/decred/dcrd/dcrec/secp256k1/v4/ecdsa#example-Signature.Verify)
Demonstrates verifying a secp256k1 signature against a public key that is
first parsed from raw bytes. The signature is also parsed from raw bytes.

Errors
Errors returned by this package are of type ecdsa.Error and fully support the
standard library errors.Is and errors.As functions. This allows the caller to
programmatically determine the specific error by examining the ErrorKind field
of the type asserted ecdsa.Error while still providing rich error messages with
contextual information. See ErrorKind in the package documentation for a full
list.

//
// However, since all group operations are done internally in Jacobian
// projective space, the algorithm is modified slightly here in order to
// avoid an expensive inversion back into affine coordinates at step 7.
// Credits to Greg Maxwell for originally suggesting this optimization.
//
// Ordinarily, step 7 involves converting the x coordinate to affine by
// calculating x = x / z^2 (mod P) and then calculating the remainder as
// x = x (mod N). Then step 8 compares it to R.
//
// Note that since R is the x coordinate mod N from a random point that was
// originally mod P, and the cofactor of the secp256k1 curve is 1, there are
// only two possible x coordinates that the original random point could have
// been to produce R: x, where x < N, and x+N, where x+N < P.
//
// This implies that the signature is valid if either:
// a) R == X.x / X.z^2 (mod P)
// => R * X.z^2 == X.x (mod P)
// --or--
// b) R + N < P && R + N == X.x / X.z^2 (mod P)

// 8. Verified if R * z == X.x (mod P)
// 9. Fail if R + N >= P
// 10. Verified if (R + N) * z == X.x (mod P)
// Step 1.
//
// Fail if R and S are not in [1, N-1].

Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on.
To aid in cross-platform testing there is a Vagrantfile for Linux and BSD.
* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/)
* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder.
* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password)
* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd fsnotify/fsnotify; go test'`.
* When you're done, you will want to halt or destroy the Vagrant boxes.
Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory.
Right now there is no equivalent solution for Windows and macOS, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads).

## API stability
fsnotify is a fork of [howeyc/fsnotify](https://godoc.org/github.com/howeyc/fsnotify) with a new API as of v1.0. The API is based on [this design document](http://goo.gl/MrYxyA).
fsnotify is a fork of [howeyc/fsnotify](https://github.com/howeyc/fsnotify) with a new API as of v1.0. The API is based on [this design document](http://goo.gl/MrYxyA).
All [releases](https://github.com/fsnotify/fsnotify/releases) are tagged based on [Semantic Versioning](http://semver.org/). Further API changes are [planned](https://github.com/fsnotify/fsnotify/milestones), and will be tagged with a new major revision number.
Go 1.6 supports dependencies located in the `vendor/` folder. Unless you are creating a library, it is recommended that you copy fsnotify into `vendor/github.com/fsnotify/fsnotify` within your project, and likewise for `golang.org/x/sys`.
