The following are
working samples of how our ASP components work on EasyASP
hosting accounts. There are literally thousands of other combinations,
colors, methods, etc that could be used to accomplish the
same functions. Please note that we do not provide support
for these samples. They are only provided as a guide to help
you get started.
Please note: When using any ASP Mail COM Objects, you
must use "localhost" or "220.127.116.11" as the mail host and "25" as the port number. We configure SMTP on
a non-routable, internal IP with an odd port number so that
people can send email through ASP scripts, without having
to deal with SMTP authentication issues.
AspEmail is an active server component (COM Object)
that enables your ASP application to send email messages
via any external SMTP server. The component supports multiple
file attachments, multiple recipients, CCs, BCCs, and REPLY-TOs.
Generic ASP FormMailer:
This is a generic ASP Form Mail sample that can be used to email ALL posted form data to one or more email addresses.
What about a simple component for "tearing" web
pages from a server? AspTear allows you to retrieve web
pages from servers easily with a bunch of features.
ASPUPload is an Active Server component which
enables an ASP application to accept, save and manipulate
files uploaded with a browser. The files are uploaded via
an HTML POST form.
The message digest algorithm was developed by Professor
Ronald L. Rivest of MIT. 'The MD5 algorithm is intended
for digital signature applications, where a large file must
be "compressed" in a secure manner before being encrypted
with a private (secret) key under a public-key cryptosystem
such as RSA.' MD5 is a hash, i.e it is not reversible without
a lot of effort.
RC4 is a variable key-size cipher (the text can be decrypted if you have the key). It was designed by Rivest for RSA. This is an implementation of how the cipher is believed to work, and not the actual encryption software, which is available from RSA.
The RSA algorithm was invented in 1978 by Ron Rivest, Adi Shamir, and Leonard Adleman. It is a public and private key cipher. The component includes an example of a public and private key, a component for creating these keys is included in the download.
