Hi,

does your API provide something to send/retrieve file & parameters from Applet to Servlet ?
Any example somewhere ?

Thanks for your support

Regards,

Yann

PDF files can be signed using our PDFBlackbox package: https://www.eldos.com/sbb/desc-pdf.php

If a file is stored on server side, but is signed on client side, then you can use our Distributed Cryptography Add-on: https://www.eldos.com/sbb/desc-dc.php.

Signed file and parameters can be transferred securely if you'll setup TLS on server side, but this can be done without SecureBlackbox as TLS support is included into all popular Java application servers.

File (from client filesystem) is signed using your API, and next
uploaded from client side
So, could you help me techniclaly to know how to send it from applet to servlet ?

i don't know what to use when you say "you'll setup TLS on server side, but this can be done without SecureBlackbox as TLS support is included into all popular Java application servers."

Thanks for your help

You can use our HTTPBlackbox package to send it securely via HTTPS. Alternatively you can use built-in HttpURLConnection class, but looks like it doesn't allow to send files as easy as our TElHTTPSClient does.

Your servlets are hosted on some application server like Tomcat or JBoss. You should refer to your server manual to check how to enable TLS support.

Hi Yann,

Just a side note, if you feel not too confident about your knowledge of HTTPS, we can implement the relevant code (both client and server sides) for you on a custom service basis.
