How to Use

1. Enter the custom alphanumeric key you want to use.(Alphanumeric means letters of A-Z and numbers 0 - 9)
   
   ⚠ Reminder: For best security, use a long (16-30 characters) random key with a mix of A-Z and 0-9. Short or simple keys may make decryption easier by brute force.
   
   
2. Enter the message you want to encrypt or encrypted characters you want to decrypt.
3. NOTE: Unigma can only process the standard English alphabet (A-Z), numbers (0-9), and standard keyboard characters such as:
   • !
   • @
   • #
   • $
   • %
   • ^
   • &
   • *
   • (
   • )
   • _
   • -
   • =
   • +
   • ~
   • [
   • ]
   • {
   • }
   • :
   • ;
   • '
   • "
   • <
   • >
   • /
   • ?
   • |
   • \
   Any character not present above will be treated as (?) (question mark).
4. Press the encrypt / decrypt button.
5. Output will be displayed in the separate text area.

About

• Keyspace Calculation:
  1. Total possible keys: 36^30 ≈ 2.2 × 10^46
  2. Far greater than the number of atoms in the universe (~10^78)
• Classical Brute Force:
  1. Even at 10^12 keys/sec, it takes ~10^34 years
  2. Much longer than the age of the universe (~10^10 years)
• Quantum Computing Impact:
  1. Grover’s Algorithm reduces complexity to 36^15 ≈ 2.2 × 10^23
  2. At 10^12 quantum ops/sec, it still takes ~7,000 years
• Conclusion:
  1. 30-character 36-based key is secured
  2. Resistant to classical and future quantum attacks
