get_arr_of_size__full_plaintext​

get_arr_of_size__full_plaintext();

|full_pt| = |pt| = (N * 32) + 64

Takes no parameters.

get_arr_of_size__plaintext_aes_padding​

get_arr_of_size__plaintext_aes_padding(_full_pt, );

|pt_aes_padding| = 16 - (|full_pt| % 16)

Parameters​

NameType
_full_pt[u8; FULL_PT]

get_arr_of_size__ciphertext​

get_arr_of_size__ciphertext(_full_pt, _pt_aes_padding, );

|ct| = |full_pt| + |pt_aes_padding|

Parameters​

NameType
_full_pt[u8; FULL_PT]
_pt_aes_padding[u8; PT_AES_PADDING]

get_arr_of_size__log_bytes_without_padding​

get_arr_of_size__log_bytes_without_padding(_ct, );

Let lbwop = 1 + HEADER_CIPHERTEXT_SIZE_IN_BYTES + |ct| // aka log bytes without padding

Parameters​

NameType
_ct[u8; CT]

get_arr_of_size__log_bytes_padding​

get_arr_of_size__log_bytes_padding(_lbwop, );

(because ceil(x / y) = (x + y - 1) // y ).

Parameters​

NameType
_lbwop[u8; LBWOP]

get_arr_of_size__log_bytes​

get_arr_of_size__log_bytes(_lbwop, _p, );

p is the padding

Parameters​

NameType
_lbwop[u8; LBWOP]
_p[u8; P]

get_arr_of_size__log_bytes_padding__from_PT​
