php - PDO and openssl_public_decrypt failing -


i trying decrypt , update password mysql database table. while doing giving me weird error.

php warning: pdo::exec(): ssl operation failed code 1. openssl error messages: error:0906d06c:pem routines:pem_read_bio:no start line in .../vendor/robmorgan/phinx/src/phinx/db/adapter/pdoadapter.php on line 306 php warning: pdo::exec(): mysql server has gone away in .../vendor/robmorgan/phinx/src/phinx/db/adapter/pdoadapter.php on line 306 php warning: pdo::exec(): error reading result set's header in ../vendor/robmorgan/phinx/src/phinx/db/adapter/pdoadapter.php on line 306

  • passwords encrypted using private key.
    • openssl_private_encrypt function used encryption.
  • decryption done using openssl_public_decrypt
  • encryption along insertion databse works fine
  • decryption along update not work. pdo::exec fails reason
  • platform using ubuntu, php 5.6.24-1+deb.sury.org~xenial+1
  • encrypt-insert, decrypt-update order of operations.
  • mysql connection open before encryption , decryption performed

code encryption decryption:

 function processplaintext($plaintext, $action) {         $crypttext = '';         $res = 'encrypt' == $action ? openssl_get_privatekey($this->keycontents) : openssl_get_publickey($this->keycontents);         $action = 'encrypt' == $action ? 'openssl_private_' . $action : 'openssl_public_'.$action;          $action($plaintext, $crypttext, $res);         openssl_free_key($res);         return $crypttext;     }

any insight on problem appreciated.

code works:

$pdo = getmysqlpdoinstance(); //get pdo instance using ssl $id = 101; $plaintext = 'abcd'; $password = processplaintext($plaintext, 'encrypt'); $count = $pdo->exec(sprintf("update table set password =  '%s' id = %d", $password, $id)); print("updated $count rows.\n");

code fails:

$pdo = getmysqlpdoinstance(); //get pdo instance using ssl $id = 101; $password = processplaintext($encryptedpassword, 'decrypt'); $count = $pdo->exec(sprintf("update table set password =  '%s' id = %d", $password, $id)); print("updated $count rows.\n");

thanks

amazon web services - S3 Pre-signed POST validate file type? -

i know it's possible put limit on file size content-length-range header. possible validate file type? https://docs.aws.amazon.com/amazons3/latest/dev/httppostforms.html#policyconditions i see there content-type header, if set say, audio/mp3 allow mp3 files , return error if file not mp3? i found previous question answers mention validating file size: s3 direct upload restricting file size , type you can specify content-type @ post request. you can specify @ signature, post must done content-type: { "expiration": "2007-12-01t12:00:00.000z", "conditions": [ {"acl": "public-read" }, {"bucket": "johnsmith" }, {"content-type: "audio/mp3"} ] } creating html form (using aws signature version 4) edit: @ previous question found, checking content-type.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
