> Mononumeric Encryption for 8086

This simple encryption program is made for the 8086 microprocessor.

In the encryption, each alphabetic letter is substituted by a

number according to the following table:

| Plain Text | Cipher Text |

| ---------- | ----------- |

| a          | 1           |

| b          | 2           |

| c          | 3           |

| d          | 4           |

| e          | 5           |

| f          | 6           |

| g          | 7           |

| h          | 8           |

| i          | 9           |

| j          | 10          |

| k          | 11          |

| l          | 12          |

| m          | 13          |

| n          | 14          |

| o          | 15          |

| p          | 16          |

| q          | 17          |

| r          | 18          |

| s          | 19          |

| t          | 20          |

| u          | 21          |

| v          | 22          |

| w          | 23          |

| x          | 24          |

| y          | 25          |

| z          | 26          |

## Solution

1. Constructing the table and storing it in the memory.

2. Writing a program to encrypt the input message

3. Decrypting the cipher text to obtain the original text message.
