/** The Electronic Code Book (ECB) mode of a block cipher, with no padding.
*
* \warning ECB mode does not protect the confidentiality of the encrypted data
* except in extremely narrow circumstances. It is recommended that applications
* only use ECB if they need to construct an operating mode that the
* implementation does not provide. Implementations are encouraged to provide
* the modes that applications need in preference to supporting direct access
* to ECB.
*
* The underlying block cipher is determined by the key type.
*
* This symmetric cipher mode can only be used with messages whose lengths are a
* multiple of the block size of the chosen block cipher.
*
* ECB mode does not accept an initialization vector (IV). When using a
* multi-part cipher operation with this algorithm, psa_cipher_generate_iv()
* and psa_cipher_set_iv() must not be called.
