invalid login or password Mcrypt error

阅读更多关于 invalid login or password Mcrypt error

问题 I' facing an issue with registered Customer through checkout. After the checkout process, the customer lands in “My Account” but once logged off, he can’t acces "My Account" anymore, the message "Invalid login or password" is displayed. Setting a new password through “Forgotten Password” button seems to solve the problem for the customer. The system.log file is displaying: Warning: mcrypt_generic_init(): Key size is 0 in /lib/Varien/Crypt/Mcrypt.php on line 94 Warning: mcrypt_generic_init():

Decrypt mcrypt with openssl

阅读更多关于 Decrypt mcrypt with openssl

问题 Since mcrypt is considered obsolete, my task is upgrading the current code to use openssl. Sounds simple, but ... after a few days of try and failure I feel like going insane. My question to you is: Is there any way you can decrypt with openssl data previously encrypted with mcrypt? I've read so many posts on this matter and most of them say that a previous manual padding of the data was/is necessary before running mcrypt on it. The issue is that the mcrypt-ed data is already encrypted (with

Generate an N-digit random number

问题 I want to generate a 6 digit random number using the PHP mt_rand() function. I know the PHP mt_rand() function only takes 2 parameters: a minimum and a maximum value. How can I do that? 回答1: Something like this ? <?php $a = mt_rand(100000,999999); ?> Or this, then the first digit can be 0 in first example can it only be 1 to 9 for ($i = 0; $i<6; $i++) { $a .= mt_rand(0,9); } 回答2: You can use the following code. <?php $num = mt_rand(100000,999999); printf("%d", $num); ?> Here mt_rand(min,max);

问题 Here is a PHP demo script that encrypts and decrypts data: <? $encryptionkey = 'h8y2p9d1'; $card_nbr = "1234"; echo "original card_nbr: $card_nbr <br>\n"; $card_nbr_encrypted=encrypt_data($card_nbr); echo "card_nbr_encrypted: $card_nbr_encrypted <br>\n"; $card_nbr_decrypted=decrypt_data($card_nbr_encrypted); echo "card_nbr_decrypted: $card_nbr_decrypted <br>\n"; $len=strlen($card_nbr_decrypted); echo "length: $len <br>\n"; function encrypt_data($text){ global $encryptionkey; $iv_size = mcrypt

Preparing for removal of Mcrypt in PHP 7.2

阅读更多关于 Preparing for removal of Mcrypt in PHP 7.2

问题 So as time moves on mcrypt will go in PHP 7.2. Of course there is an alternative: openssl. I find it difficult to switch from mcrypt to openssl, using AES 256 CBC and preserving IVs. I am sort of new to cryptography, so I don't really know everything, but I understand the basics. Let's say I have the following code function encrypt($masterPassword, $data) { $keySize = mcrypt_get_key_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_CBC); $ivSize = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_CBC);

libmcrypt and MS Visual C++

问题 Has anyone tried using libmcrypt and visual c++? I was trying to use Crypto++ but it seems not fully compatible - and I need to decrypt data encrypted in PHP using linux libmcrypt. I found only cygwin version of libmcrypt but no .lib files or header. I'm using RIJNDAEL_128 - maybe there is easier way to decrypt it in Visual C++? Thanks 回答1: I'd be surprised if Crypto++ didn't do the job frankly. It is a bit awkward to use and is fairly badly documented, but I have found it very powerful in
