Category	Encryption Keys
Severity	MEDIUM
Framework	Git

Impact

The PGP Private Key is used to decrypt messages and digitally sign messages or files.

Exposure is a Catastrophic Risk that allows an attacker to decrypt sensitive information, impersonate the key owner by forging digital signatures, and compromise the confidentiality and integrity of data.

How to Fix

To remediate a generic or high-entropy secret:

1. Identify the service or resource protected by this secret (investigate variable names or surrounding code for context).
2. Log in to the identified service and rotate the credentials.
3. If the service cannot be identified, treat the secret as critical: check if it matches internal passwords or keys and rotate them as a precaution.
4. Update your application configuration with the new value.

Next, remove the secret from your codebase:

1. Locate the exposed string in your codebase.
2. Remove it or replace it with a secure variable or reference.

Finally, clean your version control history:

1. Permanently remove the sensitive data from your version control history to ensure it cannot be retrieved.
