Web27 nov. 2024 · There are examples listed on this page but the aes examples are doing decryption rather than key unwrapping, and the wrap examples are using public keys rather than symmetrical keys. Is there some reference or example for using MBED TLS to do key-unwrapping using AES-128 encryption? WebIt should not be taken as an example of how to build a secure encryption mechanism. To derive a key from a low-entropy secret such as a password, use a standard key stretching mechanism such as PBKDF2 (provided by the pkcs5 module). To encrypt and authenticate data, use a standard mode such as GCM or CCM (both available as library module).
