不知道PHP的OpenSSL扩展是否可以生成private/public密钥/证书对?

I wonder if PHP's OpenSSL extension can be used to generate private/public key/certificate pairs?

推荐答案

当然，使用 openssl_pkey_new:

Sure, use openssl_pkey_new:

$privateKey = openssl_pkey_new(array('private_key_bits' => 2048)); $details = openssl_pkey_get_details($privateKey); $publicKey = $details['key'];

您可以使用 openssl_pkey_export 导出密钥或openssl_pkey_export_to_file.

You can export the keys with openssl_pkey_export or openssl_pkey_export_to_file.
