To interpret by use of a key refers to the process of decoding or deciphering a message, text, or code by utilizing a specific set of rules, symbols, or guidelines known as a "key" or "cipher key." This method of interpretation involves understanding and applying the predetermined patterns or instructions provided by the key to derive meaning from the given information.
When faced with a coded message or encrypted text, interpreting by use of a key involves substituting or rearranging the original characters, symbols, or numbers in accordance with the defined key. The key acts as a guide or reference, providing the necessary information to understand the hidden or encrypted content.
The key may contain instructions on how to translate individual symbols, convert numbers into letters, or shift the positions of characters within the message. It may also specify the order or arrangement of the key elements, such as a specific word or phrase to begin the deciphering process.
This method of interpretation is commonly employed in cryptography, where encoded messages are designed to be illegible without the corresponding key. By utilizing the key correctly, one can unlock and comprehend the intended meaning of the encrypted information.
In summary, "interpreting by use of a key" involves decoding a message or text using a predetermined set of rules or instructions provided by a key, enabling the deciphering of hidden or encrypted content.
