wc_AesEncryptDirect
WOLFSSL_API void 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 and iv (initialization vector) of the provided AES structure, which should be initialized with wc_AesSetKey before calling this function. It 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.
