How to set AES-256-CBC password?

To set a password for AES-256-CBC encryption, you specify it during the encryption process using the OpenSSL command. Here’s how to do it:

1. Use the following command to encrypt a file (e.g., secret.txt):

   openssl enc -aes-256-cbc -salt -in secret.txt -out secret.enc -pbkdf2

2. When you run this command, OpenSSL will prompt you to enter a password. This is where you set your AES-256-CBC password. Type your desired password and press Enter. You will be asked to confirm the password by typing it again.

3. After entering and confirming the password, OpenSSL will encrypt the file and save it as secret.enc.

Remember to choose a strong password, as it will be used to encrypt and decrypt the file.
