crypt_procedure

def crypt_procedure(chaine,table)

---

Algorithm

The crypter manager to orchestrate the crypting procedure. It works from these steps:

• We convert the given ascii string as integer list

• We compute the Base index list as key from the converted integer list

• We build the second part of the key since the mirror of the Base index list

• We compute the cumulated weight of the integer list

• We compute the point by point multiplication between cumulated weigth list and original integer list

• We transpose the multiplied list into the given specified Base from the key

• We associate the crypted strin to the key as return

Parameters	Type	Description
chaine	string	The string to crypt
table	list of list	The Base Table recursively builded

Returns

list tuple (crypt_lst,key) : The couple crypted string and key as result. It permits to decrypt any message.

int_chaine = ascii_to_int(chaine)
base_keyy  = base_key(int_chaine)
if(len(base_keyy)%2==0):
        key=base_keyy[0:int(len(base_keyy)/2)]
else:
        key=base_keyy[0:int((len(base_keyy)/2)+1)]
vec_poid   = vec_poids(int_chaine)
crypt_lst  = multlist(int_chaine,vec_poid)
crypt_lst  = transpose_base(crypt_lst,base_keyy,table)
return(crypt_lst,key)
