What does the term "encipher only" refer to in the context of encryption?

• A. Deciphering data selectively
• B. Only encrypting data, without decryption
• C. Maintaining the authenticity of certificates
• D. Conducting public key exchanges

Answer: (B)

The term "encipher only" specifically relates to the practice of converting plaintext into ciphertext without engaging in any process for returning that ciphertext back to its original form, which is known as decryption. This method emphasizes solely the encryption aspect of the data protection process, essentially meaning that the data is being transformed into a secure format to protect its confidentiality but is not subsequently decrypted or analyzed.

This approach can often be employed in scenarios where data needs to be securely transmitted or stored without necessitating immediate access to the decrypted information. It signifies a one-way transformation of data aimed at safeguarding sensitive information, hence underscoring its primary focus on the encryption mechanism alone.
