Encryption Tool

How to Use:

• Select encryption method
• Enter your text to encrypt/decrypt
• Provide a password/key (for Caesar and Substitution)
• Choose encrypt or decrypt mode
• Copy the result using the Copy button

Encryption Methods:

• Caesar Cipher: Shift letters by a number (password = shift amount)
• Substitution Cipher: Use password to create substitution key
• Base64: Encoding/decoding (not true encryption, just encoding)

Are these encryption methods secure?

These are basic, educational encryption methods. Caesar and substitution ciphers are easily broken and should not be used for sensitive data. For real security, use modern encryption like AES.

What's the difference between encryption and encoding?

Encryption requires a key to decrypt and provides security. Encoding (like Base64) is just a different representation of data and provides no security - it's easily reversible.

How do I choose a good password?

For Caesar cipher, use a number (1-25). For substitution cipher, use a word or phrase. Remember, these are educational tools, not secure encryption methods.

Can I use this for real data protection?

No! These are basic, easily breakable methods meant for learning. For real data protection, use established encryption libraries and algorithms like AES-256.
