**Encryption** is the process of using an [[dido:public:ra:xapend:xapend.a_glossary:e:encryption_algorithm]] or [[dido:public:ra:xapend:xapend.a_glossary:c:cryptographic_algorithm]] to transform information to make it unreadable for unauthorized users. This cryptographic method protects sensitive [[dido:public:ra:xapend:xapend.a_glossary:p:plaintext]] such as credit card numbers by encoding and transforming information into unreadable [[dido:public:ra:xapend:xapend.a_glossary:c:ciphertext]]. This encoded data may only be decrypted or made readable with a [[dido:public:ra:xapend:xapend.a_glossary:k:key |key]]. Symmetric-key and asymmetric-key are the two primary types of encryption.

Encryption is essential for ensured and trusted delivery of sensitive information.
