secp256k1-php

PHP bindings for https://github.com/bitcoin-core/secp256k1

Please note that the upstream library, libsecp256k1 is still considered experimental by it's authors, and has not yet been formally released. For this reason, it's use should be discouraged. For consensus systems this warning is critical.

The library supports the EcDH, and signature recovery modules - these libraries are required for installation.

Requirements

PHP 5.* versions are supported in the v0.0.x release. PHP 7 is supported in the v0.1.x series.

About the extension

• Fully unit tested, with >99 code coverage since the v0.1.3 release.
• This extension only supports deterministic signatures at present. In fact, no RNG is utilized in this extension - private keys must be generated elsewhere.
• The extension exposes the same raw API of libsecp256k1. As such, you must ensure you are passing the binary representations of each value.
• In keeping with libsecp256k1, this extension returns certain data to the user by writing to a variable reference, and returning a code indicating the failure/success.

To Install:

libsecp256k1:

    git clone [email protected]:bitcoin-core/secp256k1 && \
    cd secp256k1 &&                                    \
    ./autogen.sh &&                                    \
    ./configure --enable-experimental --enable-module-{ecdh,recovery} && \
     make &&                                           \
     sudo make install &&                              \
     cd ../

secp256k1-php:

    git clone [email protected]:Bit-Wasp/secp256k1-php && \
    cd secp256k1-php/secp256k1 &&                      \
    phpize &&                                          \ 
    ./configure --with-secp256k1 &&                    \  
    make && sudo make install &&                       \
    cd ../../

secp256k1-php's Issues

130 char long public key

Hi,
I'm using secp256k1_ec_pubkey_serialize to recover serialized public key from public key.
However it return me a 130 char long public key.
And the expected public key is the 128 right characters. I have no idea why my result is prefixed with a 0x04.
For the moment I went ahead by ignoring those 2 chars but I really want to unterstand why I got this.
Cheers,

error in benchmark.php

With a fresh git clone, as instructed in the README.

$time php -dextension=secp256k1.so ../benchmark.php > /dev/null

PHP Warning: secp256k1_ecdsa_verify() expects exactly 4 parameters, 3 given in /home/websites/secp256k1-php/benchmark.php on line 8
<... warning repeats many times ...>

Looks like it is missing the initial context parameter. But I tried adding that and got another error, so gave up for now.

(regardless, I can tell the library is working in bitcoin-php lib, because now my app is much faster.)

secp256k1_ecdsa_sign: should support noncefp and ndata

Unable to install secp256k1 on Windows PHP 7

Hello, I've been unable to compile secp256k1 on my localhost for 3 days now. The only command that works is the clone command and nothing else after that. I have PHP installed via XAMPP and if I need anything else to make it work, I'd love to know as a library I need is dependent on secp256k1. Thanks.

Critical: tests fail on php7.1/7.2

Seems we have a segfault in secp256k1_ec_pubkey_create, which is causing test failures on 7.1 / 7.2

Use zend_api macros to assign type hints - aka strict types

It looks like some macros have existed since php 7.0 that let you assign php7 type hints to function arguments and return types. A scan of the php codebase shows that barely any functions use them, but they work great with the ReflectionExtension API, so you can generate php7 aware stubs if we go this route.

Going to hold back on this one a little while until I'm sure they're meant to be used yet, I really don't want to end up using something that breaks often. (or would force us maintaining separate PHP7.0/7.1/7.2 code bases..)

Depends on libsecp2561k1 being installed on the host

We should be able to build against a copy of libsecp256k1 in git, to avoid the constant breaks in upstream software when libsecp25k1 upgrades. .

I think there are examples of this out there (zip in php-src, for example) but config.m4 scripts are horrible to digest.

Any extension developers who can help, please do get in touch.

secp256k1_ec_pubkey_serialize - fix API

upstream now takes serialization flags, which we generate in place based on fCompressed.

we should remove fCompressed in favor of directly accepting serialization flags.

See #101

The tests take forever to start..

I read that travis lets you use container based builds, which are quicker to start up. Apparently it decides this based on whether you use sudo - which we do to install the libsecp256k1 library.

If we can avoid running sudo make install somehow hopefully we'll see some speed in the run time :/

Publish on PECL

Please publish this extension to PECL, so it's more easily available.

secp256k1_ecdsa_recoverable_signature_serialize_compact - fix API

Saving this for a backwards incompatible release, but it looks like

    secp256k1_ecdsa_recoverable_signature_serialize_compact(
         resource $context, 
         resource $sig, 
         &$sigOut, 
         &$recID
    );

is wrong and should be

    secp256k1_ecdsa_recoverable_signature_serialize_compact(
         resource $context, 
         &$sigOut, 
         &$recID, 
         resource $sig
    );

Add valgrind run to CI

as mentioned in #131, we should have travis run valgrind tests.

recently I've done some work on this using a php build from source with the following:
./buildconf && ./configure --with-valgrind --with-pcre-valgrind --with-secp256k1 && make -j8

with the projects secp256k1 dir located in ./ext/secp256k1 and then using the following to run valgrind tests: make test TESTS="./ext/secp256k1/tests -m"

ideally we'd be able to run this on multiple php versions - maybe several Docker files in phpqa?

When will this project support PHP7?

Do you have a schedule?

Critical: potentially invalid derivations? (php7.3 only?)

this one is scary - very recently, on travis php nightly builds I started getting invalid derivations in bip32 and electrum derivations. the culprit seems to be one of the priv/pub_tweak_add functions. I have yet to investigate this one, but it is of the utmost importance that if you use ext-secp256k1 that you have a comprehensive test suite covering your derivation code, lest something like this ever slip into production.

Talk to bitcoin core?

I saw that at the moment PHP can only communicate over JSON RPC to bitcoin core. Also no push notifications are supported. For node.js there seem to be bindings https://github.com/bitpay/bitcore-node Could this extension provide similar functionality? An example of a notifcation would be a transaction getting verified.

Track code coverage

We'll have to compile PHP with gcov support for this, but really nice to have going forward.

Write simple test.php files

The build I used first time around created skeleton test files. Should remove them or just add some simple cases (prefer the latter)

How to generate private key?

Hi, I am wondering how to generate private key with this ropo?

And in the example create_public_key.php , there is a comment: //Private keys are never generated by secp256k1. Then how could I generate a private key?

Thanks for any information!

And by the way, could I use this library whth composer? I didn't find the "composer require" information for this library.

PHP8 Install Error

Hello there,

Recently upgraded to PHP8.0 and want to install this extension. Everything works fine until I hit the make command when in the secp256k1-php/sec256k1 folder.

This is the error I'm seeing:

/secp256k1-php/secp256k1/secp256k1.c:1995:47: error: expected ‘)’ before ‘TSRMLS_CC’
     if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "rz/rS|flz",

 ZEND_API zend_result zend_parse_parameters(uint32_t num_args, const char *type_spec, ...);

I don't know anything about C or PHP extensions so I don't know where to start to try and fix this. Can anyone help?

Clean up API, should match libsecp256k1

Leaving this as a TODO - some functions parameters are ordered differently, which will need to be changed. Also the flags API break hasn't been carried on to the extension, besides the constants values changing, secp25k1_ec_pubkey_serialize still takes a long for compressed, and flags are generated from this.

Also - secp256k1_ecdsa_verify normalizes all signatures rather than passing them directly to libsecp256k1's secp256k1_ecdsa_verify function.

Add DESTDIR support

I will try to do this when I get home after holidays and submit a patch to makefile if it is not done by then, but DESTDIR support would make installing in a package manager build environment (e.g. RPM) a lot easier.

error callbacks

We don't have support for configuring error callbacks. It'd be nice to add these for completeness.

secp256k1_ecdsa_verify: don't copy & normalize

ie, preserve upstreams semantics of rejecting signatures which are not normalized. Looking back on it, it was probably done to be helpful, but it's best not to introduce different behaviors I think.

PR is simple, but opening the issue to bring some visibility to what I'd call an issue, feedback would be welcome!

Installation Error

Hey guys

When I try that last line of the installation,
phpize && ./configure --with-secp256k1 && make && sudo make install

I get this error.

make: ** [secp256k1.lo] Error 1

Secp256k1 failed to parse public key

I am getting this error from my application somewhat erratically but frequently. Once it starts to happen, it seems to be repeatable with successive executions for the same xpub.

If I disable the secp256k1 extension and run again without any code changes (using bitwasp/bitcoin-php lib) it always executes without fail.

So I get the feeling the extension is (randomly?) getting wedged into an unhappy state and then staying that way.

Sorry I do not have a simple test case at present. If I find/devise one, I will attach it.

The xpub that failed in this particular case was:
xpub697odnriKgTgWE4my6au8nd8haUfAMzLGFpDemAkRbCMgGVxANuj9DffNLgDjPA1dnxzi8oFmM79ZPgKVfCV7Saj8sQUL7tJfeZDuyQNGDm

Output from my program with relevant stack trace was:
