* The application must call psa_cipher_encrypt_setup() or
* psa_cipher_decrypt_setup() before calling this function. The choice
* of setup function determines whether this function encrypts or
* decrypts its input. After calling a setup function, if the chosen
* algorithm requires an IV, the application must call
* psa_cipher_generate_iv() or psa_cipher_set_iv().
* Before calling this function, you must:
* 1. Call either psa_cipher_encrypt_setup() or psa_cipher_decrypt_setup().
* The choice of setup function determines whether this function
* encrypts or decrypts its input.
* 2. If the algorithm requires an IV, call psa_cipher_generate_iv()
* (recommended when encrypting) or psa_cipher_set_iv().
*
* If this function returns an error status, the operation becomes inactive.
