aesEncryptEcb

Function for encrypting with AES algorithm.

Detailed Description

returns a vector of type xor_uint32 with the encrypted values

Function Overloads

D xor_uint32 aes128EncryptEcb(D xor_uint32[[1]] expandedKey, D xor_uint32[[1]] plainText)

Parameters

expandedKey

- an aes128 expanded key of type xor_uint32. See also aesGenkey and aesExpandKey

plainText

- a string converted to a xor_uint32 vector

the size of expandedKey has to be dividable by (AES128_Nb * (AES128_Nr + 1))

the size of plainText has to be dividable by AES128_Nb

( plainText / AES128_Nb ) == ( size of expandedKey ) / (AES128_Nb * (AES128_Nr + 1))

None
