How to decrypt in PHP and OpenSSL?

[emitof9999]

Hi,

I totally no idea how to decrypt it in PHP and shell based OpenSSL.

Attempted to decrypt, but nothing to be print out.. Means maybe mode, IV or key is different....

Meanwhile, how to encrypt it with AES-256? It looks like not support aes-256-cbc

This is my PHP code :

openssl_decrypt(base64_decode("5hg/Q7t65Oa0uPZAKC5GJZ6JGFGvrKJzJOkNtxgkLm0="), $aes_mode, $key, OPENSSL_RAW_DATA, base64_decode($IV));

Thank you.

Regards,

Gordon

Finally i found solution from others forum to resolved my problem

Dart:

  var aesEncrypter = AesCrypt('my 32 length key................', 'cbc', 'pkcs7'); //generate AES CBC block encrypter with key and PKCS7 padding
  var iv = 'my 32 length key';
  String encrypted = aesEncrypter.encrypt('somedatahere', iv); //encrypt
  String decrypted = aesEncrypter.decrypt(encrypted, iv); //decrypt

  print(encrypted);
  print(decrypted);

PHP:

var_dump(openssl_decrypt(base64_decode($ENCRYPTED_FROM_DART), "AES-256-CBC", "my 32 length key................", OPENSSL_RAW_DATA, "my 32 length key"));
