解密

$txt="ytecn";
$pubkey="私钥"
$macdata=RSAEncrypt::decrypt($txt,$pubkey);

类文件

classRSAEncrypt{
publicstaticfunctionencrypt($str,$publicKey){
$pubKey=openssl_pkey_get_public($publicKey);
openssl_public_encrypt($str,$outStr,$pubKey);
returnbase64_encode($outStr);
}

publicstaticfunctiondecrypt($str,$privateKey){
$inputByte=base64_decode($str);
$decoded=base64_decode($privateKey);
$priKey=openssl_pkey_get_private($decoded);
openssl_private_decrypt($inputByte,$outStr,$priKey);
return$outStr;
}
}
