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 decrypt the original text from the hash value.
