php-ext-oqs: post-quantum cryptography for PHP

Native PHP extension for post-quantum key encapsulation (ML-KEM) and signatures (ML-DSA, SLH-DSA), with liboqs built in.

php-ext-oqs is a native extension (no FFI) built on the C library liboqs from the Open Quantum Safe (OQS) project. The prebuilt binaries contain liboqs, so there is no system library to install.

Status: experimental. liboqs states that it is meant for research and prototyping and is not currently recommended for production use or for protecting sensitive data. The same applies to this extension, which has not been independently audited.

It provides an object-oriented API for the NIST-standardized PQC algorithms ML-KEM (Kyber), ML-DSA (Dilithium), SLH-DSA (SPHINCS+), and other algorithms supported by liboqs.

Influenced and inspired by great DEF CON 33 - Post Quantum Panic talk by K Karagiannis.

Features

Key Encapsulation Mechanisms (KEMs): Securely generate and exchange shared secrets using algorithms like ML-KEM.
Digital Signature Schemes (SIGs): Create and verify signatures with algorithms like ML-DSA.
Modern API: A clean, object-oriented interface (Oqs\Kem, Oqs\Sig).
Type Safe: Exposes algorithm identifiers as class constants (e.g., Oqs\Kem::ALG_ML_KEM_768) for safe, typo-free code and IDE autocompletion.
Exception-based Error Handling: Throws Oqs\Exception for clear error handling.

Requirements

PHP 8.1+ (prebuilt binaries: PHP 8.1 - 8.5, non-thread-safe, Linux glibc x86_64/arm64 and macOS arm64)
Nothing else for the prebuilt binaries: liboqs is linked statically into oqs.so.
Only when building from source: PHP development headers (php-dev, phpize), a C compiler, make, cmake, and liboqs.

Project files

config.m4 - contains the code that will go into the configure script. checks for the oqs/oqs.h header and uses pkg-config to find the liboqs library, fallback to a hardcoded prefix
php_oqs.h - header file containing C declarations and macro definitionsto be shared between several source files. defines the necessary object structs (php_oqs_kem_obj, php_oqs_sig_obj) and utility functions for fetching these objects
oqs.c (module init + class registration) sets up the module entry, defines the custom object handlers, and registers the Oqs\Kem and Oqs\Sig classes with their respective methods
sig.c (module init + class registration)
kem.c (module init + class registration)
tests - unit tests

Development Notes

Safety: The extension has no module globals and no per-request state; the only state is the liboqs handle owned by each Oqs\Kem / Oqs\Sig object.
Input validation: keys and ciphertexts of the wrong length are rejected with Oqs\Exception before they reach liboqs. Sig::verify() returns false for a signature of impossible length.
Output Format: All cryptographic outputs (keys, ciphertexts, signatures) are returned as raw binary strings.
liboqs Version: release 0.2.0 bundles liboqs 0.16.0 (each release names its bundled liboqs in CHANGELOG.md; php --ri oqs shows it at runtime). Because liboqs is linked statically, a liboqs security fix reaches you through a new release of this extension, not through a system update. The set of ALG_* constants follows whatever the linked liboqs enables, so it changes between liboqs releases (0.16.0 dropped the SPHINCS+-* names in favour of SLH-DSA, and added HQC, eFrodoKEM and MQOM).

Installation

Every release ships prebuilt binaries. They contain liboqs, so there is nothing to compile and no library to install.

Platform	PHP	Asset
Linux x86_64 (glibc 2.34+: Debian 12+, Ubuntu 22.04+, RHEL 9+, official `php` Docker images)	8.1 - 8.5 NTS	`php_oqs-<version>_php<X.Y>-x86_64-linux-glibc.zip`
Linux arm64 (same)	8.1 - 8.5 NTS	`php_oqs-<version>_php<X.Y>-arm64-linux-glibc.zip`
macOS 13+ Apple Silicon	8.1 - 8.5 NTS	`php_oqs-<version>_php<X.Y>-arm64-darwin-bsdlibc.zip`

Not covered yet: Alpine (musl), thread-safe (ZTS) PHP, Intel Macs, Windows. On those, build from source (below).

With PIE

PIE picks the right binary for your PHP, installs it and enables it:

pie install guycalledseven/php-ext-oqs

If there is no binary for your platform, PIE falls back to a source build. That needs liboqs on the system and its location: pie install guycalledseven/php-ext-oqs --with-oqs=/usr/local.

Manual download

VERSION=0.2.0
PHP_MM=$(php -r 'echo PHP_MAJOR_VERSION, ".", PHP_MINOR_VERSION;')
ASSET="php_oqs-${VERSION}_php${PHP_MM}-x86_64-linux-glibc.zip"     # pick the asset for your platform
curl -fsSLO "https://github.com/guycalledseven/php-ext-oqs/releases/download/$VERSION/$ASSET"
unzip -o "$ASSET" oqs.so -d "$(php -r 'echo ini_get("extension_dir");')"

Then enable it by adding extension=oqs to a php.ini (php --ini lists the files in use), and check:

php --ri oqs

macOS only: a file downloaded with a browser is quarantined, clear that once with xattr -d com.apple.quarantine "$(php -r 'echo ini_get("extension_dir");')/oqs.so".

In a Dockerfile

FROM php:8.4-cli
ARG OQS_VERSION=0.2.0
RUN set -eux; \
    arch="$(uname -m | sed 's/aarch64/arm64/')"; \
    curl -fsSL -o /tmp/oqs.zip "https://github.com/guycalledseven/php-ext-oqs/releases/download/${OQS_VERSION}/php_oqs-${OQS_VERSION}_php${PHP_VERSION%.*}-${arch}-linux-glibc.zip"; \
    php -r '$z = new PharData("/tmp/oqs.zip"); $z->extractTo(ini_get("extension_dir"), "oqs.so", true);'; \
    rm /tmp/oqs.zip; \
    docker-php-ext-enable oqs

Building from source

The release binaries are produced by ci/build.sh, which builds liboqs and the extension in a scratch directory, runs the tests and writes the zip to dist/:

ci/build.sh                 # for the PHP on your PATH
ci/docker-build.sh 8.4      # Linux binary, inside the official php:8.4-cli-bookworm image

The manual steps follow.

Debian:

sudo apt install cmake libssl-dev php-dev

macOS:

brew install cmake

Build liboqs for static linking

Install liboqs into a prefix outside this directory. make clean deletes every *.a below the extension directory, which would silently remove a liboqs installed inside it.

git clone --depth=1 --branch 0.16.0 https://github.com/open-quantum-safe/liboqs
OQS_PREFIX="$(cd .. && pwd)/deps/liboqs-0.16.0"    # or /usr/local (then install with sudo)
cmake -S liboqs -B liboqs/build \
  -DCMAKE_BUILD_TYPE=Release \
  -DBUILD_SHARED_LIBS=OFF \
  -DOQS_BUILD_ONLY_LIB=ON \
  -DOQS_USE_OPENSSL=OFF \
  -DCMAKE_POSITION_INDEPENDENT_CODE=ON \
  -DCMAKE_INSTALL_PREFIX="$OQS_PREFIX"
cmake --build liboqs/build --parallel
cmake --install liboqs/build

build php extension

phpize --clean; phpize
OQS_COMMIT=$(git -C liboqs rev-parse --short HEAD) ./configure --with-oqs="$OQS_PREFIX"
make clean && make -j

An explicit --with-oqs=DIR always wins over pkg-config. If DIR/lib/liboqs.a exists it is linked statically (-force_load on macOS, --whole-archive on Linux); configure fails if DIR contains no liboqs at all.

confirm if static

otool -L modules/oqs.so
# Expected: does NOT list liboqs.*dylib. Only /usr/lib/libSystem.B.dylib.

Check which liboqs actually got linked (headers and library versions must agree):

php -d extension=$PWD/modules/oqs.so --ri oqs | grep liboqs

Build the extension with dynamically linked liboqs (optional)

Build liboqs

git clone --depth=1 https://github.com/open-quantum-safe/liboqs
cmake -S liboqs -B liboqs/build -DBUILD_SHARED_LIBS=ON -DOQS_DIST_BUILD=ON
cmake --build liboqs/build --parallel
sudo cmake --build liboqs/build --target install
sudo ldconfig || true

Build extension

rm -rf build/* run-tests.php
phpize

# macOS

Important Security Point - clarification of the role of a KDF

KEM implementation returns a raw shared secret. In practice, this shared secret should almost never be used directly as an encryption key. It should be used as input to a Key Derivation Function (KDF) like HKDF to produce keys of the desired length and properties.

It is strongly recommended to use PHP's built-in hash_hkdf() function.

// Example of best practice
[$ct, $shared_secret] = $kem->encap($pk);

// Now, derive a 32-byte AES key and a 16-byte IV from the shared secret
$keying_material = hash_hkdf('sha256', $shared_secret, 48, 'my-app-encryption', 'some-salt');
$aes_key = substr($keying_material, 0, 32);
$iv = substr($keying_material, 32, 16);

Quick start

<?php
use Oqs\Kem;
use Oqs\Sig;

// 1. Key Encapsulation (KEM) Example with ML-KEM
$kem = new Kem(Kem::ALG_ML_KEM_768);

// Generate a public/private key pair
[$publicKey, $secretKey] = $kem->keypair();

// A client encapsulates a secret against the public key,
// generating a ciphertext and a shared secret.
[$ciphertext, $sharedSecretA] = $kem->encap($publicKey);

// The server decapsulates the ciphertext with the secret key
// to derive the same shared secret.
$sharedSecretB = $kem->decap($ciphertext, $secretKey);

assert($sharedSecretA === $sharedSecretB);
echo "KEM shared secrets match!\n";


// IMPORTANT: The raw shared secret should be passed through a KDF
// like HKDF before being used as an encryption key.
$encryption_key = hash_hkdf('sha256', $sharedSecretA, 32, 'my-app-aes-key');


// 2. Digital Signature (SIG) Example with ML-DSA
$sig = new Sig(Sig::ALG_ML_DSA_65);

// Generate a signing key pair
[$signingPublicKey, $signingSecretKey] = $sig->keypair();

$message = "This is the message to sign.";

// Sign the message with the secret key
$signature = $sig->sign($message, $signingSecretKey);

// Verify the signature against the message and public key
$isValid = $sig->verify($message, $signature, $signingPublicKey);

assert($isValid === true);
echo "Signature is valid!\n";

3. Algorithm Details

You can retrieve detailed metadata about an algorithm using the details() method.

$kem = new Oqs\Kem('Kyber512');
$details = $kem->details();
print_r($details);
/* Output:
Array
(
    [name] => Kyber512
    [version] => ...
    [claimed_nist_level] => 1
    [ind_cca] => 1
    [length_public_key] => 800
    [length_secret_key] => 1632
    [length_ciphertext] => 768
    [length_shared_secret] => 32
)
*/

PHP API test

use Oqs\Kem;
use Oqs\Sig;
use Oqs\Exception as OqsException;

$kem = new Kem('ML-KEM-768');
$s = $kem->sizes();                 // ['pk'=>..,'sk'=>..,'ct'=>..,'ss'=>..]
[$pk,$sk] = $kem->keypair();        // returns [pk, sk] as binary strings
[$ct,$ssA] = $kem->encap($pk);      // encaps → [ciphertext, shared_secret]
$ssB = $kem->decap($ct, $sk);       // decaps → shared_secret
assert($ssA === $ssB);

$sig = new Sig('ML-DSA-65');
[$spk,$ssk] = $sig->keypair();
$signature = $sig->sign("hello", $ssk);
$ok = $sig->verify("hello", $signature, $spk); // bool

Kem::algorithms(); // list enabled KEM names
Sig::algorithms(); // list enabled SIG names


try {
    // This will now throw an Oqs\Exception
    $kem = new Kem('Some-Invalid-Algorithm');

} catch (OqsException $e) {
    // This block will ONLY catch exceptions thrown from your extension.
    echo "Caught an OQS-specific error: " . $e->getMessage();

} catch (\Exception $e) {
    // Other general errors would be caught here.
    echo "Caught a generic error: " . $e->getMessage();
}

Comparation with similar php extension php-liboqs:

Object-oriented API design vs static.
Error handling with a custom Oqs\Exception.
Complete function signatures (arginfo) for better IDE/static analysis support.
An extra useful method (Kem::sizes()).
