Public Key Certificates
Zygma uses cryptographic keys for the functions described below.  The corresponding public key certificates may be downloaded by selecting the links below.  We recommend that you download these keys and verify them, so as to verify the keys' fingerprints, by contacting Zygma by whatever means gives you sufficient confidence.  Also, by clicking the banner above (with the 'sigma' key symbol) you will get an enlarged version of the hex codes, within which you will find (in grey) the fingerprints of the keys available for download, against which you may make a preliminary confirmation.

Signing PDF documents - PDF documents downloadable from this web-site are all signed by Zygma to indicate that they were made available for downloading by Zygma.  Most of these documents are originated by Zygma, although some from other sources may also be signed, simply to confirm that Zygma has deliberately placed them on its web-site.  Where Zygma is not the originator or does not have copyright in a document the document will be devoid of any such claim - the act of signing is merely for the sake of the site's integrity, not an attempt to claim copyright on material not owned by Zygma.

Zygma may also sign other PDF documents (e.g. reports, contracts & agreements, invoices, ...) exchanged with business colleagues (clients, associates, ...) using the same signing key.  We would rather do this than mess with faxes or even 'snail'-mail where possible, appropriate and acceptable to the other party.

Signing and encrypting email and documents- PGP keys are used to protect email exchanges where another other party has a PGP mail agent and has provided a compatible PGP key which Zygma has determined to be trustworthy.  In such cases the respective keys will be used to sign and encrypt outgoing mail and to authenticate and decrypt incoming mail.  Where Zygma holds and trusts a PGP key from another source it may, subject to applicable legislation and any required agreement with the other party, encrypt file content such that only the selected parties can gain access to the file concerned.  Zygma will also accept and decrypt any information encrypted under its own PGP public key where it holds a trusted key from the originator (from which you may conclude that, unless the originator is known and trusted, no decryption shall take place before attempts have been made to verify the identity and intentions of the originator).
