int wc_AesEncryptDirect(Aes *aes, byte *out, const byte *in)
This function is a one-block encrypt of the input block, in, into the output block, out. It uses the key of the provided AES structure, which should be initialized with wc_AesSetKey before calling this function. wc_AesSetKey should have been called with the iv set to NULL. This is only enabled if the configure option WOLFSSL_AES_DIRECT is enabled. Warning: In nearly all use cases ECB mode is considered to be less secure. Please avoid using ECB API’s directly whenever possible.
