WebSteganography is the technique of hiding secret data within an ordinary, non-secret, file or message in order to avoid detection; the secret data is then extracted at its destination. The use of steganography can be combined with encryption as an extra step for hiding or protecting data. WebDigital signatures are based on public key cryptography, also known as asymmetric cryptography. Using a public key algorithm -- such as Rivest-Shamir-Adleman, or RSA -- two keys are generated, creating a mathematically linked pair of keys: one private and one public. on the empirics of sudden stops
