Cryptography fascinates everyone. A variety of encryption techniques and ciphers are used to code important data.
A polyalphabetic cipher is one of the simplest cipher one can make. This is a Java program to implement polyalphabetic cipher.

[How the cipher encodes?]

Input Data: helloaf
Key: love

l - 12th letter in Alphabet
o - 15th letter in Alphabet
v - 22nd letter in Alphabet
e - 5th letter in Alphabet

Now:

h(l) e(o) l(v) l(e) o(l) a(o) f(v)

Further:

h(+12) e(+15) l(+22) l(+5) o(+12) a(+15) f(+22)

where +(number) meaning shifting the character forward by the respective number of places.

So the result comes out to be:
tthqapb
and the data is encrypted.

Features

  • Convert your text into encrypted text using a key and decrypt it anytime using the same key.
