Which is Correct: 'Decrypt' or 'Unencrypt'?

A commonly observed debate in the world of cybersecurity and cryptography is whether the correct term is 'decrypt' or 'unencrypt.' The consensus among professionals in the field is that 'decrypt' is the accurate term to use.

Decryption is the process of converting encrypted data back into its original form. Terminology in the realm of encryption is critical, and 'unencrypt' is not a standard term in cryptography. Instead, 'encryption' refers to the act of securing data, and 'decryption' is the process of restoring it to its original form. Both terms can be used as verbs, but 'decrypt' is generally preferred due to its simplicity and clarity.

Usage and Meaning

If you start with encrypted data and end up with unencrypted data, the correct term is 'decrypted data.' On the other hand, you would refer to data that has not been encrypted as unencrypted data. 'Unencrypt' is not a verb and should not be used to describe the process of converting encrypted data back into its original form.

For example, if you encrypt the contents of a hard drive to prevent unauthorized access, and then remove that protection, this is considered unencrypting. However, if a hacker cracks the encryption through vulnerabilities, that process is considered decryption. While both actions convert data from one form to another, 'decrypt' clearly conveys the idea of deciphering a coded message, whereas 'unencrypt' would imply simply removing a non-existent encryption.

Terminology in Cryptography

Decryption implies breaking an encryption, whereas 'unencrypt' implies reversing an encryption. Imagine two scenarios: if you have a locked safe with encrypted data, unencrypting it would mean making the safe accessible without disturbing the lock. On the other hand, if a hacker has a copied key and knows a weak spot in the lock, cracking the safe would be considered decryption.

The term 'decrypt' is widely used in cryptographic literature and is also recognized by major cybersecurity tools and platforms. While 'unencrypt' may occasionally be used in the context of 'unencrypted data' (which is simply plaintext or cleartext that has not been encrypted), it is not a preferred term.

Conclusion

While both 'decrypt' and 'unencrypt' can be used to describe the removal of encryption, 'decrypt' is the correct and more commonly accepted term in the field of cryptography. It is concise and explicitly conveys the process of converting encrypted data back to its original form.
