This calculator converts milliamp-hours (mAh) to watt-hours (Wh) using voltage, which is the same battery-capacity relationship used for Ah and Wh. The page includes the formula, direct input fields, and the reverse conversion link. It is free to use without a required paid plan.
The binary to text converter will allow you to convert strings into binary numbers, using different encodings.
The Vigenère Cipher provides an interactive platform for encrypting and decrypting text using one of the most famous polyalphabetic substitution methods. By applying a keyword to shift characters across multiple alphabets, it adds a layer of complexity beyond simple substitution ciphers. Users can explore the mechanics of the algorithm through a Tabula Recta visualization, which clearly maps how plaintext and keys interact to produce ciphertext. Security enthusiasts and students of cryptography can perform deep analysis on encrypted messages using integrated tools like Kasiski examination and Index of Coincidence. These features help identify repeating patterns and key lengths, facilitating automated key recovery for educational or testing purposes. Whether for learning the history of codes or analyzing ciphertext, this resource offers a comprehensive set of tools for classical cryptanalysis.
