在openssl_public_encrypt()中Get the key参数不是有效的公钥错误

Question

$publickey=“../ssh/public/pub”；$plaintext=“要加密的字符串”；

$pubKey = openssl_pkey_get_public($publicKey);

openssl_public_encrypt($plaintext, $encrypted, $pubKey);

echo $encrypted;   //encrypted string

openssl rsa-in/path/to/privatekey-pubout-out/path/to/publickey

Answer 1

在我的例子中，我把公钥拆分成多行，解决了这个问题。

PHP版本7.1.17

    $publicKey = "-----BEGIN PUBLIC KEY-----\n" . wordwrap($publicKey, 64, "\n", true) . "\n-----END PUBLIC KEY-----";

    $str = "str to be encrypted";

    $opensslPublicEncrypt = openssl_public_encrypt($str, $encrypted, $publicKey);
