Encrypting with AES in Openssl
If you are looking to encrypt data with the AES algorithm using OpenSSL, you can do so with the command line tool. Here is an example:
openssl enc -aes-256-cbc -salt -in plaintext.txt -out encrypted.txt
In this example, we are using the AES-256-CBC cipher, which is an AES cipher in CBC mode with a 256-bit key. We are also using salt to add randomness to the encryption process. The plaintext is read from the file
plaintext.txt, and the encrypted data is written to
You can also specify a password for the encryption with the
openssl enc -aes-256-cbc -salt -in plaintext.txt -out encrypted.txt -k mypassword
In this case, the password is
Keep in mind that the encryption process may take some time for large files or if using a high level of security. It is also important to keep your password or key secure, as it is the only way to decrypt the data.
Overall, OpenSSL provides a convenient and secure way to encrypt data with the AES algorithm. Be sure to read the documentation and understand the options available for your specific use case.
