Write Java program to Implement Rail Fence Cipher

Cryptography

Rail Fence Cipher

Interactive Java implementation — encrypt and decrypt text using the columnar rail fence transposition technique

Encryption

Writes plaintext column-wise into a matrix, then reads row-wise to produce ciphertext

Decryption

Writes ciphertext row-wise into a matrix, then reads column-wise to recover the original text

Depth Key

The depth value determines the number of rows in the transposition matrix
