CipheringPoems
For the 26th day of NaPoWriMo/NaPoGenMo 2024, the poem is being generated through Transposition ciphers coded in Python.
"A Transposition cipher is one in which the order of characters is changed to obscure the message."https://math.libretexts.org/Bookshelves/Applied_Mathematics/Math_in_Society_(Lippman)/16%3A_Cryptography/16.03%3A_Transposition_Ciphers
Input 1:
[['H' 'O' 'E']
['T' 'W' 'N']
['S' 'D' 'D']
['E' 'S' 'Y']
['E' 'R' 'E']]
Input 2:
[['O' 'R' 'E']
['B' 'A' 'R']
['E' 'N' 'D']
['S' 'T' 'Y']
['X' 'E' 'A']]
Transposed Output
Transposed 1:
[['H' 'T' 'S' 'E' 'E']
['O' 'W' 'D' 'S' 'R']
['E' 'N' 'D' 'Y' 'E']]
Transposed 2:
[['O' 'B' 'E' 'S' 'X']
['R' 'A' 'N' 'T' 'E']
['E' 'R' 'D' 'Y' 'A']]
Output
Real Phrase:
['T' 'H' 'E' 'S' 'E']
['W' 'O' 'R' 'D' 'S']
['N' 'E' 'E' 'D' 'Y']
Real Phrase 2:
['B' 'O' 'X' 'E' 'S']
['A' 'R' 'E' 'N' 'T']
['R' 'E' 'A' 'D' 'Y']
