PHP 下的SSL加密设置

这个是报的错
[Composer\Downloader\TransportException]
  The "http://packages.zendframework.com/packages.json" file could not be downloaded: SSL operation failed with code 1. OpenSSL Error messages:
  error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
  Failed to enable crypto

将证书安装到
~$ mkdir ~/tools/https-ca
 ~$ cd ~/tools/https-ca
 ~$ curl http://curl.haxx.se/ca/cacert.pem -o cacert.pem

地址在
/Users/jackluo/tools/https-ca/cacert.pem

然后修改php.ini文件
openssl.cafile=/Users/jackluo/tools/https-ca/cacert.pem

这样至少不报错了

gitconfig 证书:
export GIT_CURL_VERBOSE=1 
~$ git config --global http.sslCAInfo /Users/jackluo/tools/https-ca/cacert.pem

可打开~/.gitconfig确认cainfo配置成功写入git配置文件

function sign($data) {
    //读取私钥文件
    $priKey = file_get_contents('key/rsa_private_key.pem');
 
    //转换为openssl密钥，必须是没有经过pkcs8转换的私钥
    $res = openssl_get_privatekey($priKey);
 
    //调用openssl内置签名方法，生成签名$sign
    openssl_sign($data, $sign, $res);
 
    //释放资源
    openssl_free_key($res);
 
    return $sign;

    //调用openssl内置方法验签，返回bool值
    $result = (bool)openssl_verify($data, $sign, $res);

    $res = openssl_get_privatekey($priKey);

    //循环按照128位解密
    for($i = 0; $i < strlen($content)/128; $i++  ) {

    //拆分开长度为128的字符串片段通过私钥进行解密，返回$decrypt解析后的明文
        openssl_private_decrypt($data, $decrypt, $res);
 
    //明文片段拼接
        $result .= $decrypt;
    }
 
    //释放资源
    openssl_free_key($res);
 
    //返回明文
