后台私钥php解密
public function rsa(){
if($this->request->isPost()){
$encrypted=$this->request->post('encrypted');
//私钥 PKCS8(JAVA适用)
$pri ='MIICdwIBADANBgkqhkiG9w0BAQEFAASCAmEwg';
//PKCS1(非JAVA适用) 解密不了
//$pri ='MIICWwIBAAKBgQCXn41kvOtvur5bwUMW';
//解密方式一
$pem = chunk_split($pri, 64, "\n");
$pem = "-----BEGIN PRIVATE KEY-----\n" . $pem . "-----END PRIVATE KEY-----\n";
$prikeyid = openssl_pkey_get_private($pem);
$crypttext = base64_decode($encrypted);
if (openssl_private_decrypt($crypttext, $sourcestr, $prikeyid, OPENSSL_PKCS1_PADDING))
{
$this->success('成功','',['后台解密结果'=> $sourcestr]);
}
//解密方式二，我用的fastadmin系统，自带了rsa解密类，如果系统没有请使用解密方式一
/* $rsa=new \fast\Rsa('',$pri);
$this->success('成功','',['后台解密结果'=> $rsa->privDecrypt($encrypted)]);*/
}
return $this->view->fetch();
}
***如果解密不了，整理下公钥的字符串格式，还有就是生成的非JAVA的私钥也是解密不了的
