| Post subject: | YubiHSM acting as an oracle |
I'm trying to find out if I can have a YubiHSM act as an oracle - that is, I set some secret key on the YubiHSM, then I pass the HSM a value for encryption (or decryption) and I get back the encrypted (or decrypted) result. For example, after initializing the YubiHSM with a secret key, I might do something like this: Code: encrypted_value = yubihsm_encrypt(plaintext_to_protect) decrypted_plaintext = yubihsm_decrypt(encrypted_data) Is this something I can do, preferably in C/C++, or is the best I can do have the YubiHSM act as storage for the secret keys? |
