🔄 Caesar Cipher
🔐 Security Analysis
Caesar cipher provides low security as it only has 25 possible keys, making it vulnerable to brute force attacks.
🔠 Playfair Cipher
🔐 Security Analysis
Playfair encrypts letter pairs, which can hide single-letter patterns better than a simple substitution. It is still a historical cipher with known weaknesses and is not suitable for modern security.
🔑 RSA Cipher
🔐 Security Analysis
This simplified RSA implementation is for education only. Real RSA-based systems require carefully implemented, modern cryptographic libraries; do not use this demo to protect sensitive information.
💪 Brute Force Analysis
📊 Analysis Results
🔑 Vigenere Cipher
Encrypt or decrypt alphabetic text using a repeating keyword. Non-letter characters are preserved. Learn about Vigenere.
🔁 ROT13 Converter
Apply ROT13 to letters. Applying it again reverses the transformation. Learn about ROT13.
🔃 Atbash Cipher
Map A to Z, B to Y and so on. The same operation enciphers and deciphers. Learn about Atbash.
🚂 Rail Fence Cipher
Arrange text in a zigzag across rails, then read each rail in sequence. Learn about Rail Fence.
