Crypto vs Cipher Pixel

Dive into cryptography with Crypto. Use Caesar and Vigenère ciphers and encrypt and decrypt messages. CRYPTO Crypto allows you to encrypt and decrypt messages using Caesar and Vigenère ciphers. Create a message, select a key or a keyword, and then send the encrypted message to your friends. Similarly can you decrypt encrypted messages. CIPHERS In both Caesar and Vigenère ciphers, each letter is substituted with another, which makes them substitution ciphers. Only those who know the secret key are able to decrypt messages, though it is possible to decrypt an encrypted message without knowing the key by using brute force. CAESAR CIPHER In the case of Caesar’s cipher, we use a secret integral key (k). This secret key is used to rotate (i.e. shift) each letter by k places, wrapping A to Z and a to z as needed. For example, if we use the key of 1 to encrypt “Hello world!”, we will get “Ifmmp xpsme!” To decrypt this message, shift the letters backward. VIGENÈRE CIPHER Vigenère cipher improves upon Caesar cipher by shifting letters using different keys. This sequence of keys is known as a keyword. Each letter in the keyword represents by how far the corresponding letter in the original message will be shifted (A and a represent 0, B and b represent 1, Z and z represent 25). If we encrypt “Hello world!” with the keyword “Squirrel”, we will get “Zuftf nscdt!”

Cipher Pixel: Hide Messages in Your Photos With Cipher Pixel, you can securely send hidden messages or keep them safely hidden within images in your gallery. Cipher Pixel makes it easy to hide secret messages in your photos. Using the ancient technique of steganography, this app conceals information within the pixels of your images. Unlike cryptography, which scrambles data into unreadable text, steganography hides data in plain sight, ensuring secrecy without drawing attention. Why Choose Cipher Pixel? Seamless Integration: Effortlessly hide messages in your photos without changing their appearance. User-Friendly Design: Encode and decode messages with ease using a simple interface. Advanced Security: Encrypt your secret messages using the AES algorithm before embedding them in your photos, ensuring that your hidden data is protected with an extra layer of security. How It Works: Encode: Input your message, and Cipher Pixel transforms it into bits. Encrypt: Secure your message with AES encryption before hiding it in the image. Embed: Select a photo, and let Cipher Pixel discreetly hide your encrypted message within its pixels. Share Securely: Share your photo confidently, knowing your hidden message is safe. Additional Note: Once you have created an image with a secret message hidden in the Cipher Pixel app, be careful not to resize or compress the image when sharing it. When sending an image using messaging applications, the image must be sent as a 'Document'. If you send it as an image, the saved message may be lost. This is because messaging applications change the image format.
