Multi platform crypto options for Nag et al Was: Submiting patch for nrpe

[Stanley Hopcroft]

Dear Sir,

I am writing to thank you for your letters about this matter and note
that

. SSL/TLS is a multi-platform facility that provides encryption and
strong authentication. Support for a large range of ciphers (inc AES and
Blowfish) as well as certificates is built in (what is a cert ? simply a
token of identity, that is difficult to forge).

. SSL/TLS is provided IIRC by the built in MS crypto provider or use the
industrial strength multi-platform OpenSSL (https://www.OpenSSL.ORG)

. SSL/TLS can be used in some applications _transparently_. Adding TLS
support to a Perl LWP client is as simple as installing one Perl module
and using https:// URLs instead of http://

If I was doing crypto, although I am no coder, this is the approach I
would take.

TLS/SSL simply gives you sockets that encrypt and decrypt your data
after setting up 'session'.

Session negotiation allows the selection of ciphers and the enforcement
of client and server identification.

Yours sincerely.

'...No man is an island, entire of itself; every man is a piece of the
continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'
