Certificate decoding and encoding\n  - Certificate signing\n- Certification requests ([PKCS #10](https://tools.ietf.org/html/rfc2986))\n  - CSR decoding and encoding\n- Certification path\n  - Path building\n  - Path validation\n- Attribute certificates ([RFC 5755](https://tools.ietf.org/html/rfc5755))\n  - AC decoding and encoding\n  - AC signing\n\n## Requirements\n\n- PHP \u003e=7.2\n- gmp\n- [sop/asn1](https://github.com/sop/asn1)\n- [sop/x501](https://github.com/sop/x501)\n- [sop/crypto-types](https://github.com/sop/crypto-types)\n- [sop/crypto-bridge](https://github.com/sop/crypto-bridge)\n- [sop/crypto-encoding](https://github.com/sop/crypto-encoding)\n\n## Installation\n\nThis library is available on\n[Packagist](https://packagist.org/packages/sop/x509).\n\n    composer require sop/x509\n\n## Code examples\n\nExamples are located in\n[`/examples`](https://github.com/sop/x509/tree/master/examples)\ndirectory.\n\n- [Create a CA certificate](https://github.com/sop/x509/blob/master/examples/create-ca-cert.php)\n- [Create a CSR](https://github.com/sop/x509/blob/master/examples/create-csr.php)\n- [Issue a certificate](https://github.com/sop/x509/blob/master/examples/issue-cert.php)\n- [Validate a certification path](https://github.com/sop/x509/blob/master/examples/path-validate.php)\n\n## License\n\nThis project is licensed under the MIT License.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsop%2Fx509","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsop%2Fx509","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsop%2Fx509/lists"}
