I have generated an symmetric key using the below command. openssl rand base64 512 > sym.key Using this key ( sym.key ) I have encrypted a file with below command. openssl enc -aes-256-cbc -in temp.txt -out temp.enc -kfile sym.key It has generated an encrypted file temp.enc . Now, I have to use the same key ( sym.key ) with EVP Decrypt API's and have to decrypt this encrypted file. Could any one suggest me a better approach for this. Here is the code unsigned

This programm is provided by the customer and cannot be changed (they are using this code for legacy applications). As you can see in the code below the customer provides a passphrase so the key will be generated using the SecretKeySpec method. Java code: // Passphrase private static final byte[] pass = new byte[] { '0', '1', '2', '3', '4', '5', '6', '7', '8', '9', '0','1', '2', '3', '4', '5' }; public

The data packet is saved in a uint8_t* variable and encrypted. Until this part is all going well.

I found a nice example in stackoverflow with which I have started programming. What I would like to know is: What is the default padding used while encryption? What happens if I have large data. Do I have to code to divide it into data blocks of 128 bits? or does EVP interface takes care of it? What should be the size of the IV for 128bit, 192bit and 256bit cbc modes(where only the key lengths are 128, 192, 256 respectively and the block size

I'm new to encryption. This question is subquestion of my previous one.
