Encryption: One can send an e-mail
encrypted and "(R)egistered". Encryption
prevents any non-authorized party from reading or
changing data in an e-mail message en route. The
level of protection provided by encryption is determined
by an encryption algorithm and requires a public
key and/or secure key exchange. RPost is compatible
with most standard public key infrastructure digital
certificates.
RPost is compatible with standard PKI digital certificates
and is not itself an issuer of certificates. For
instructions on using encryption with RPost services,
consult your RPost user manual or contact RPost.
RPost is also compatible with PKI Digital Signatures,
as this service is primarily used to pass the sender's
public key to the recipient so the intended recipient
of an encrypted e-mail can decrypt that e-mail and
read it. This generally only needs to be used once
to pass along the sender's decryption key to intended
recipients. Digital Signatures also tell the recipient
that the e-mail originated from the indicated sender
and has not changed en route. However, if the e-mail
is forwarded on, or the recipient is not viewing
in a compatible e-mail program, the Digital Signature
becomes invalid.
Alternatively, a user interested in additional privacy
in their e-mail may type the sensitive information
into a word processing program such as Word or Adobe
and save with a password restriction or password
encryption. They would then attach this encrypted
file to their e-mail and send it via Registered
E-mail®.
RPost adds proof of delivery and proof of content
delivered for the encrypted e-mail adding accountability
to the extra privacy provided by encryption techniques. |
