Security Recommendations
- Classical ciphers are not secure for modern encryption needs
- Use only for educational purposes or simple obfuscation
- Vigenère cipher with a long, random key provides better security
- Never use classical ciphers for sensitive information
Cipher Information
Caesar Cipher
A substitution cipher where each letter is shifted by a fixed number down the alphabet.
Key: Number between 1-25 (shift amount)
Vigenère Cipher
An advanced substitution cipher that uses a keyword to determine the shift for each letter.
Key: Any word or phrase (letters only)
Atbash Cipher
A simple substitution cipher where A↔Z, B↔Y, C↔X, etc.
Key: None needed
Substitution Cipher
Each letter is replaced by another specific letter in the alphabet.
Key: 26-letter string representing the substitution alphabet (e.g., "ZYXWVUTSRQPONMLKJIHGFEDCBA" for reverse alphabet)
Rail Fence Cipher
A transposition cipher that writes the message in a zig-zag pattern and reads it row by row.
Key: Number of rails (typically 2-10)
Historical Context
These ciphers were used historically but are easily broken with modern cryptanalysis techniques. They are included here for educational purposes to demonstrate basic cryptographic principles.
CipherTool is a powerful encryption app that supports various cipher algorithms for securing and decoding messages. Perfect for privacy and learning cryptography.
