a) Encryption – A process of transforming plaintext into ciphertext. Encryption is the method by which plaintext or any other type of data is converted from a readable form to an encoded version that can only be decoded by another entity if they have access to a decryption key. Encryption is one of the most important methods for providing data security, especially for end-to-end protection of data transmitted across networks.

b) Decryption – Decryption is
generally the reverse process of encryption. A process of transforming ciphertext into plaintext. Where it is the process of decoding the data which has been encrypted into a secret format. An authorized user can only decrypt data because decryption requires a secret key or password.

c) Plaintext – Can be defined as
the original message. Plain text, as you might have guessed, is rather plain. It supports standard characters, including numbers, symbols, and spaces, but does not support any type of text formatting. Where it cannot apply bold, italic, or underlined styles, and cannot use different fonts or font sizes in a plain text document.

d) Ciphertext
– Known as an encrypted message. Cipher is an algorithm which is applied to plain text to get ciphertext. It is the unreadable output of an encryption
algorithm. The term "cipher" is sometimes used as an alternative term for ciphertext. Ciphertext is not understandable until it has been converted
into plain text using a key.

e) Keys - Some
critical information used by the cipher, where is it known only to the sender and receive. A cryptographic key is a string of bits used by a cryptographic algorithm to transform plain text into cipher text or vice versa. This key remains private and ensures secure communication.The length of the key is a factor in considering how
difficult it will be to decrypt the text in a given message.

a) Encryption : Encryption is the process of using an algorithm to transform information to make it unreadable for unauthorized users. This cryptographic method protects sensitive data such as credit card numbers by encoding and transforming information into unreadable cipher text. User will given a key to open the encoding data.

b) Decryption : Decryption is generally the reverse process of encryption. It is the process of decoding the data which has been encrypted into a secret format. An authorized user can only decrypt data because decryption requires a secret key or password.

c) Plaintext : Plaintext is ordinary readable text. That include any text file format that only contain text and does have any special text formating.

d) Ciphertext : Cipher is an algorithm which is applied to plain text to get ciphertext. It is the unreadable output of an encryption algorithm. The term "cipher" is sometimes used as an alternative term for ciphertext. Ciphertext is not understandable until it has been converted into plain text using a key.

e) Keys : In cryptography, a key is a variable value that is applied using an algorithm to a string or block of unencrypted text to produce encrypted text, or to decrypt encrypted text. The length of the key is a factor in considering how difficult it will be to decrypt the text in a given message.

Encryption is one of the most important methods for providing data security, especially for end-to-end protection of data transmitted across networks.

Decryption : the process of converting encrypted data back into its original form, so it can be understood

Plaintext : any text, text file, or document that contains only text. Unlike a rich-text document, a plain text file cannot have bold text, fonts, larger font sizes, or any other special text formatting. In the picture is a visual example of plain text vs. formatted text.

Cipertext : is a term used to describe any text or other data that is encrypted. For example, below is an example of ciphertext made using a substitution cipher.

Key: a piece of information that determines the functional output of a cryptographic algorithm. For encryption algorithms, a key specifies the transformation of plaintext into ciphertext, and vice versa for decryption algorithms. Keys also specify transformations in other cryptographic algorithms, such as digital signature schemes and message authentication codes.

Encryption- Encryption is the process of encoding a message or information in such a way that only authorized parties can access it and those who are not authorized cannot. Encryption does not itself prevent interference, but denies the intelligible content to a would-be interceptor.

Decryption- Decryption is the process of transforming data that has been rendered unreadable through encryption back to its unencrypted form. In decryption, the system extracts and converts the garbled data and transforms it to texts and images that are easily understandable not only by the reader but also by the system. Decryption may be accomplished manually or automatically. It may also be performed with a set of keys or passwords.

Plaintext- Plaintext is a loose term for data (e.g. file contents) that represent only characters of readable material but not its graphical representation nor other objects (floating-point numbers, images, etc.). It may also include a limited number of characters that control simple arrangement of text, such as spaces, line breaks, or tabulation characters (although tab characters can "mean" many different things, so are hardly "plain").

Ciphertext- Ciphertext is encrypted text. Plaintext is what you have before encryption, and ciphertext is the encrypted result. The term cipher is sometimes used as a synonym for ciphertext, but it more properly means the method of encryption rather than the result.

Keys- A cryptographic key is a string of bits used by a cryptographic algorithm to transform plain text into cipher text or vice versa. This key remains private and ensures secure communication.

A cryptographic key is the core part of cryptographic operations. Many cryptographic systems include pairs of operations, such as encryption and decryption. A key is a part of the variable data that is provided as input to a cryptographic algorithm to execute this sort of operation. In a properly designed cryptographic scheme, the security of the scheme is dependent on the security of the keys used.

Decryption - is the process of transforming data that has been rendered unreadable through encryption back to its unencrypted form.
Plaintext - is unencrypted information, as opposed to information encrypted for storage or transmission. Plaintext usually means unencrypted information pending input into cryptographic algorithms, usually encryption algorithms.
Ciphertext - is the result of encryptiob performed on plaintext using an algorithm, called a cipher. It is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it.
Keys - is a set of instructions that is used to encrypt and decrypt data. Sometimes used to describe a CD-KEY or serial key.

Encryption - the process of converting information or data into a code, especially to prevent unauthorized access.

Decryption - is the process of taking encoded or encrypted text or other data and converting it back into text that you or the computer can read and understand. This term could be used to describe a method of un-encrypting the data manually or with un-encrypting the data using the proper codes or keys.

Plaintext - unencrypted information, as opposed to information encrypted for storage or transmission.

Ciphertext - is encrypted text and encrypted result. The term cipher is sometimes used as a synonym for ciphertext, but it more properly means the method of encryption rather than the result.

(c) Plaintext - is the term used to refer to the information in plain language that the sender desires to send to one or more receiving computers or individuals. Also referred to as cleartext, plaintext is commonly referred as the input to a cipher or encryption algorithm. The term cleartext can also refer to sounds, images or other multimedia information that is transmitted without encryption. In laymen’s terms, plaintext refers to information that is represented in its “normal” form before any action is taken to conceal or compress the data.

(d) Ciphertext - cipher is an algorithm which is applied to plain text to get ciphertext. It is the unreadable output of an encryption algorithm. The term “cipher” is sometimes used as an alternative term for ciphertext. Ciphertext is not understandable until it has been converted into plaintext using a key.
