AES-256/CBC encryption with OpenSSL and decryption in C#

I am a newbie to cryptography. My requirement is to decrypt/encrypt the text that is encrypted/decrypted using openssl. The algorithm that we are using is aes-256-cbc in the Openssl. So, I am trying to implement the same functionality in my application. so far after a lot of googling all i was able to do is.. private static string Encryptor(string TextToEncrypt) { //Turn the plaintext into a byte array. byte[] PlainTextBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(TextToEncrypt); //Setup the AES providor for our purposes. AesCryptoServiceProvider aesProvider = new AesCryptoServiceProvider()

Why are RijndaelManaged and AesCryptoServiceProvider returning different results?

Here is the example that I have run. It has the same Mode, Padding, BlockSize, KeySize. I am using the same init vector, key and data. Using the RijndaelManaged produces an encrypted value of: 0x8d,0x81,0x27,0xc6,0x3c,0xe2,0x53,0x2f,0x35,0x78,0x90,0xc2,0x2e,0x3b,0x8a,0x61, 0x41,0x47,0xd6,0xd0,0xff,0x92,0x72,0x3d,0xc6,0x16,0x2b,0xd8,0xb5,0xd9,0x12,0x85 Using the AesCryptoServiceProvider produces an encrypted value of: 0x8d,0x9f,0x6e,0x99,0xe9,0x54,0x8b,0x12,0xa9,0x88,0x1a,0x3d,0x65,0x23,0x9c,0x4e, 0x18,0x5a,0x89,0x31,0xf5,0x75,0xc5,0x9e,0x0d,0x43,0xe9,0x86,0xd4,0xf3,0x64,0x3a Here is the code I

per my question Aes Encryption... missing an important piece , I have now learned that my assumption for creating a reversible encryption on a string was a bit off. I now have public static byte[] EncryptString(string toEncrypt, byte[] encryptionKey) { var toEncryptBytes = Encoding.UTF8.GetBytes(toEncrypt); using (var provider = new AesCryptoServiceProvider()) { provider.Key = encryptionKey; provider.Mode = CipherMode.CBC; provider.Padding = PaddingMode.PKCS7; using (var encryptor = provider.CreateEncryptor(provider.Key, provider.IV)) { using (var ms = new MemoryStream()) { using (var cs = new
