Good evening everyone,
I am currently looking for information on PGP, and more specifically on information retrieval via a "keybase". Recently, I had a discussion with very interesting people who were able to identify an email address solely from a PGP fingerprint. They used a keybase that lists PGP fingerprints to carry out their research.
However, I am not very familiar with this concept of "keybase". Could someone explain to me how it works exactly? What are the advantages and limitations of this method of information retrieval?
If you have examples of "keybase" or resources to recommend to me to learn more, I would be very grateful.
Thank you in advance for your help and advice.
