DNACrypt

Encrypt files into DNA chromosomes! 🧬

Introduction

This project can:

• Read/Write DNACrypt Key files
  • Generate Key files
• Encrypt/Decrypt Files

Encryption/Decryption Procedure

Encryption

1. Read the file and key file
2. Parse every key
3. Shift every byte in the file with the corresponding key
4. Transform every byte into AT or GC
5. Add random bytes
6. Write to file

Decryption

1. Read the file and key file
2. Discard random bytes
3. parse the remaining DNA bytes into numbers
4. Parse every key
5. Un-shift each byte with the corresponding key
6. Write to file

Key Generation/Parsing

Generation

1. Generate n random integers from 0 to 10
2. Transform each of the integers, i to i 0s and 10 - i 1s
3. Transform each 0 to AT and 1 to GC
4. Add random bytes and a version header
5. Write to a key file

Parsing

1. Read the key file
2. Discard random bytes
3. Transform each AT to 0 and GC to 1
4. Transform the Os and 1s to a binary string , then convert to decimal
