The role of an encryption algorithm is specifically to convert plaintext into ciphertext. This process ensures that the original data, which is easily readable and understandable, is transformed into a format that is not easily decipherable without the proper key or mechanism for decryption. This conversion is central to maintaining the confidentiality of sensitive data during storage and transmission.

By converting data into ciphertext, encryption algorithms protect it from unauthorized access. The only way to retrieve the original plaintext is through a decryption process, which typically requires a secure key. This functionality solidifies the importance of encryption in safeguarding information against eavesdropping or interception, making it a fundamental component in the realm of information security.

Other roles associated with data protection, like managing data backups or preventing unauthorized access, may involve encryption but are not primarily defined by the process of transforming data into a secure format. Scrambling data visually may not necessarily involve the same level of security provided by a proper encryption algorithm, as it can refer to formats that are still susceptible to analysis.
