You need to decrypt customer data to provide it to an application.

Comprehensive and Detailed In-Depth Explanation:

The Vault Transit secrets engine returns decrypted data in base64-encoded format :

B. The output is base64 encoded : " All plaintext data must be base64-encoded before being encrypted by Vault. As a result, decrypted data is always base64 encoded. " Users must decode it (e.g., using base64 -d) to see cleartext.

Incorrect Options :

A. Permission Issue : Permissions would cause an error, not encoded output. " Not because the user lacks permission. "

C. Wrapped Token : The output is plaintext, not a token. " Not a response wrapped token. "

D. Original Encryption : Irrelevant; the issue is encoding, not encryption state.

This encoding ensures safe transmission of binary data.
