Webthe plaintext that corresponds to the ciphertext. This definition already looks better and can even be found in some texts on cryptography. However, after some more thought, it is also far from satisfactory. For example, an encryption scheme that reveals 90% of the plaintext would still be considered secure under this definition, as long as ... WebJul 26, 2010 · 3 Answers. Encryption takes a plain text and converts it to an encrypted text using a key and an encryption algorithm. The resulting encrypted text can later be decrypted (by using the same key and algorithm). A digest takes a plain text and generates a hashcode which can be used to verify if the plain text is unmodified but cannot be used to ...
