Is there any info anyone can share regarding how any of the more popular marketplaces (e.g. Agore or Evolution) store sensitive user information such as user info, orders, shipping addresses, and messages?
What types of user data would LE or other nefarious individuals be able to access if one were to gain access to the systems that store the data?
I would suspect these marektplaces use some level level of encryption to protect data at rest, but obviously the method which you encrypt and use the keys is very important. Do any of the sites use asymmetric encryption to ensure only the receiver of the data can view sensitive information?
This is the whole reason PGP exists. You encrypt all the sensitive data in the vendors PGP key so nobody can read it but them...this means if a market is compromised by LE the information is not in clear text. Encrypt sensitive data and never send anything linking your buying account to your identity without encrypting it in PGP.
