What is data called that is to be encrypted by inputting into an encryption algorithm
What is Data EncryptionData encryption is a method of converting data from a readable format (plaintext) into an unreadable, encoded format (ciphertext). Encrypted data can only be read or processed after it has been decrypted, using a decryption key or password. Only the sender and the recipient of the data should have access to the decryption key.

As you deploy an encryption solution, you should be aware that encryption is vulnerable to attack from several directions:
Nevertheless, data encryption can deter hackers from accessing sensitive information, and is essential to most security strategies. Your security strategy should not, however, solely rely on encryption. DES & Other Popular Encryption AlgorithmsData Encryption Standard (DES) is a now-outdated symmetric encryption algorithm—you use the same key to encrypt and decrypt a message. DES uses a 56-bit encryption key (8 parity bits are stripped off from the full 64-bit key) and encrypts data in blocks of 64 bits. These sizes are typically not large enough for today’s uses. Therefore, other encryption algorithms have succeeded DES:
Data At Rest and Database EncryptionData at rest is data that does not travel between networks or devices. It includes data on a laptop, hard drive, flash drive, or database. Data at rest is attractive to attackers as it often has meaningful file names and logical structures, which can point to personal information, credit cards, intellectual property, healthcare information, etc. If your company does not properly dispose of its data assets, it can create security risks for itself and its customers. Always assume that attackers can access data at rest. Minimizing the amount of data at rest, keeping an inventory of all remaining data, and securing it, is key to preventing data breaches. Database EncryptionIn most modern applications, data is input by users, processed by applications, and then stored to a database. At a lower level, the database consists of files managed by an operating system, stored on physical storage such as a flash hard drive. Encryption can be performed at four levels:
Four levels of data encryption Encryption Techniques and Technologies
The Downside of Database EncryptionDatabase encryption can result in performance degradation, in particular when column-level encryption is used. Thus, organizations may be reluctant to use data encryption or apply it to all data at rest. Many RDBMS systems provide built-in encryption and key-management facilities. Database encryption is thus easier to carry out if a data center uses databases from only one vendor. If you manage databases from multiple vendors, key management can become an issue, and lapses in key management can lead to security breaches. An additional risk is accidental data loss. When data is encrypted using strong ciphers, and a key is lost, the data cannot be retrieved. Accidental loss or mismanagement of keys can have disastrous consequences.

What is data called that is to be encrypted?In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext.
What is data called that is input into a cryptographic algorithm?Plaintext. Plaintext data is input into a cryptographic algorithm (also called a cipher), which consists of procedures based on a mathematical formula to encrypt and decrypt the data. Ciphertext. the scrambled and unreadable output of encryption.
What is called encryption algorithm?An encryption algorithm is the method used to transform data into ciphertext. An algorithm will use the encryption key in order to alter the data in a predictable way, so that even though the encrypted data will appear random, it can be turned back into plaintext by using the decryption key.
What are the 2 types of data encryption?There are two types of encryption in widespread use today: symmetric and asymmetric encryption. The name derives from whether or not the same key is used for encryption and decryption.
