A **Cryptographic Algorithm**, or **cipher** or **Encryption Algorithm** or **Decryption Algorithm**,  the means of altering data from a readable form (also known as **plaintext**) to a protected form (also known as **ciphertext**), and back to the readable form. Changing **plaintext** to **ciphertext** is known as **[[dido:public:ra:xapend:xapend.a_glossary:e:encryption]]**, whereas changing **ciphertext** to **plaintext** is known as **[[dido:public:ra:xapend:xapend.a_glossary:d:decryption]]**.
