HashiCorp HCVA0-003 Exam - Topic 2 Question 20 Discussion

After decrypting data using the Transit secrets engine, the plaintext output does not match the plaintext credit card number that you encrypted. Which of the following answers provides a solution?$ vault write transit/decrypt/creditcard ciphertext="vault:v1:cZNHVx+sxdMEr......."Key: plaintext Value: Y3JlZGl0LWNhcmQtbnVtYmVyCg==
C) The resulting plaintext data is base64-encoded. To reveal the original plaintext, use the base64 --decode command
A) Vault is sealed, therefore the data cannot be decrypted. Unseal Vault to properly decrypt the data
B) The user doesn't have permission to decrypt the data, therefore Vault returns false data
D) The data is corrupted. Execute the encryption command again using a different data key

[All HCVA0-003 Questions]

After decrypting data using the Transit secrets engine, the plaintext output does not match the plaintext credit card number that you encrypted. Which of the following answers provides a solution?

$ vault write transit/decrypt/creditcard ciphertext="vault:v1:cZNHVx+sxdMEr......."

Key: plaintext Value: Y3JlZGl0LWNhcmQtbnVtYmVyCg==

Show Suggested Answer Hide Answer
Suggested Answer: C

Comprehensive and Detailed in Depth

A: Sealing would prevent decryption, not return encoded data. Incorrect.

B: Permission issues don't return encoded data. Incorrect.

C: Transit returns base64-encoded plaintext; decoding Y3JlZGl0LWNhcmQtbnVtYmVyCg== yields ''credit-card-number''. Correct.

D: No evidence of corruption; it's a format issue. Incorrect.

Overall Explanation from Vault Docs:

''All plaintext data must be base64-encoded... Decode it to reveal the original value.''

Corruption seems unlikely. I’d stick with C for decoding.

B could be a problem too. Permissions might be an issue.

I doubt it's A. If it was sealed, we wouldn't get any output.

But what if the Vault is sealed? That could be A.

Yeah, I agree. The output looks like encoded data.

I think it's C. Base64 encoding makes sense.

Definitely C, just decode it and you'll see the original number!

B seems plausible, but I think permissions are usually clear-cut.

Wait, I thought the data couldn't be corrupted if encrypted properly?

I disagree, A makes more sense if the Vault is sealed.

I vaguely recall a question about data corruption. If the data is corrupted, we might need to re-encrypt it, right?

I feel like we discussed permissions affecting decryption. If the user doesn't have the right permissions, could that cause issues?

I'm not entirely sure, but I think if the Vault is sealed, it wouldn't let us decrypt anything at all.

I remember something about base64 encoding from our practice sessions. Could it be that the output is just encoded?
