About Acéré Cipher

The Acéré Cipher is a sophisticated substitution cipher with multiple operation modes. It provides enhanced security through various encryption techniques.

Cipher Modes

Standard: Basic letter substitution (A→Z, B→Y, etc.)
Shift: Caesar cipher with customizable shift value
Keyed: Uses a keyword to create a custom substitution alphabet
Random: Generates a random substitution for maximum security

Features

Real-time text statistics and character frequency analysis
Encryption strength evaluation
Operation history with timestamps
Multiple cipher modes for different security needs

Example (Standard Mode): "HELLO" becomes "SVOOL"

Example (Shift Mode, shift=3): "HELLO" becomes "KHOOR"

Frequently Asked Questions

What is the Acéré Cipher?

The Acéré Cipher is a sophisticated substitution cipher that offers multiple encryption modes including Standard (Atbash), Shift (Caesar), Keyed, and Random substitution. It provides various levels of security for different use cases.

How secure is the Acéré Cipher?

The security varies by mode. The Standard and Shift modes provide basic security suitable for casual use. The Keyed and Random modes offer stronger security, with the Random mode providing the highest level of security among the available options.

Can I use this tool for sensitive information?

While the Acéré Cipher provides encryption, it's primarily designed for educational purposes and casual use. For highly sensitive information, we recommend using industry-standard encryption algorithms like AES.

What is the difference between the cipher modes?

Standard: Simple letter reversal (A→Z, B→Y, etc.)
Shift: Each letter is shifted by a fixed number (Caesar cipher)
Keyed: Uses a keyword to create a custom substitution alphabet
Random: Creates a completely random substitution for maximum security

Does this tool store my encrypted data?

The tool only stores your encryption/decryption history locally in your browser for convenience. No data is sent to any server, ensuring your information remains private.

How does the frequency analysis work?

The frequency analysis tool counts how often each character appears in your text and displays the results visually. This is useful for cryptanalysis, as different languages have characteristic letter frequency patterns that can help break simple substitution ciphers.
