openssl_pkey_get_public没有打开公钥,"没有起始行"错误

Question

生成公钥然后用函数openssl_pkey_get_public读取它- $ publicKeyResource = bool(false)和消息: 错误:0906D06C:PEM例程:PEM_read_bio:无起始行

$privateKey = openssl_pkey_new(array('private_key_bits' => 2048, 'private_key_type' => OPENSSL_KEYTYPE_RSA));

$keyDetails = openssl_pkey_get_details($privateKey);

$publicKeyResource = openssl_pkey_get_public($keyDetails['key']);

怎么了？

PS

privateKey = 

array(3) {
  ["bits"]=>int(2048)

  ["key"]=>
  string(451) "-----BEGIN PUBLIC KEY-----

Answer 1

与我在PHP + OpenSSL中给出的答案相同:错误返回,但结果正确:这显然是由openssl_pkey_get_public()引起的,它需要一个包含公钥而不是公钥的证书 - 它似乎加载公钥但仍然导致此错误.看那里的细节.

Answer 2

使用 phpseclib 的 Crypt_RSA 可能会更轻松。例如。

创建密钥（2048））；回显 $publickey; ?>
