In code, each word in the message is replaced by a code word or symbol, whereas in cipher, each letter is replaced with another cipher letter or symbol. With regards to the LSIC complexity, for each cipher round, we need 2 operations/pixel (o/p) to generate a 256 × 256 keyed Latin square, 2 o/p to apply Latin square whitening, 2 o/p to implement Latin square permutation, and 2 o/p to perform Latin square substitution using this keyed Latin square. Complex ciphers can puzzle even trained cryptanalysts. The key used to encrypt and decrypt and it also needs to be a number. The JavaScript code which runs this translator was directly copied from the rosetta code page. The atbash cipher is a simple substitution cipher from Biblical times; it reverses the alphabet such that each letter is mapped to the letter in the same position in the reverse of the alphabet (A -> Z, B -> Y). Shift Cipher. The 1 position for example is assigned to letter a. A=01 N=14 B=02 O=15 C=03 P=16 D=04 Q=17 E=05 R=18 F=06 S=19 G=07 T=20 H=08 U=21 I =09 V=22 J=10 W=23 K=11 X=24 L=12 Y=25 M=13 Z=26 So there are 25 keys. These are much stronger than one-part codes.
