SimplePrivacy vs EncryptLens

SimplePrivacy uses a very simple to understand and at the same time effective one-time pad encryption technique - you could do this with pencil and paper, but SimplePrivacy will make it much easier for you. Every character of your text will be encrypted or decrypted with one character of your key by just adding them together: Plaintext: HELLO Key: ABCDE Encrypted Text: HFNOS Encryption: H + A = H E + B = F L + C = N L + D = O O + E = S Decryption: H - A = H F - B = E N - C = L O - D = L S - E = O If the key contains real random characters and is only used once for the encryption/decryption of a text this is a very safe encryption technique. But be careful: if you use the same key twice, your secret key can be easily discovered with the help of crypto-analysis. You can group the characters of the encrypted/decrypted texts to different word lengths and you can share your texts with other applications. SimplePrivacy also provides a consolidated view where you can directly see how the encryption works, by putting plaintext (blue), key (red) and encrypted text (green) below each other.

EncryptLens is an educational app designed to make the core principles of cryptography accessible and engaging. With an intuitive, interactive interface, users can explore four major encryption techniques: Caesar Cipher: Shift letters of the alphabet and see how small changes affect message security. Substitution Cipher: Customize letter mappings to create unique encryption keys and discover the challenge of decryption without the key. RSA Encryption: Follow the process of key generation and observe how asymmetric encryption transforms messages for secure communication. Hashing: Enter text and see how different algorithms generate unique hash outputs, demonstrating concepts like the avalanche effect and hash collisions. Each section is crafted to spark curiosity and enhance understanding through hands-on, visual experiences. Ideal for students, security enthusiasts, and anyone interested in how data protection works in the digital world.
