Since January 20, 2017, all emails sent by me are digitally signed to guarantee their authenticity, that's why they always carry an attached text file called "signature.asc" which contains the signature of the message.

Using this signature and the public key associated with each of my email addresses, it is possible to verify that the message was written by me and that it did not suffer any further alterations.

The public keys to perform this check are available at this and other key servers, and can also be downloaded directly from the following links:

• Public key of the email consulta@lascartas... (mails related to tarot consultations).

• Public key of the email boletin@lascartas... (mails related to this site newsletter (in spanish)).

• Public key for email nacho@lascartas... (for personal issues).
