无法解密数据 - openssl_private_decrypt():key参数不是有效的私钥

Question

<?php

Decrypted Data = 

Answer 1

// Decrypt the data using the private key and store the results in $decrypted
openssl_private_decrypt($encrypted, $decrypted, openssl_pkey_get_private($privKey, "phrase"));

echo "<br/>";
echo "Decrypted Data = ".$decrypted;
echo "<br/>";

openssl_private_decrypt函数能够使用PEM格式的私钥,但您的密钥是加密的,并且此函数没有密码参数.你必须openssl_pkey_get_private改用.
