I am using Tresorit on Mac OS X and iPhone.
When I am using it there is always applied client-side encryption before posting the file to cloud. The key used for encryption is AES-256 and CFB mode of operation is used.
But I… Continue reading How is Tresorit client-side encryption key stored and managed?
I have been using RSA SecureID ® Keys for quite some time now (perhaps 10 years), for things such as securely my home banking account online or accessing my company’s network of computers from home. These keys generate a 6-digit numeric to… Continue reading How do RSA SecureID ® Keys Work?
I’m looking for different kinds of applications which is intentionnaly (or not) made vulnerable and so are suitable for practicing different penetration techniques, like SQL injections, buffer overflows and such.
Is it fundamentally possible to validate that an unmodified version of your client connects to your server?
I was just thinking about the idea of having my client-side app hash its own source code and sends that as a key to the server with… Continue reading Is it fundamentally possible to validate that an unmodified version of your client connects to your server?
Assuming I have a server/client topology, currently I’m facing the problem that I want to generate some key on the client side and somehow make the remote server get it securely.
I’m using AES on both parts, so basically what I need is t… Continue reading How to securely share key between two remote devices?
I’m trying to develop a website that performs digital signatures on client-side and then sent the signed document to the server-side. I want to do the signatures on client, due to the fact of not sending away the user’s private key. This k… Continue reading Digital Signatures of XML, PDF and Office Documents on every platform

I’m looking for a client-side encryption implementation that would be able to secure CardDav & CalDav data so that they couldn’t be compromised even by the hosting provider.
Server side: PHP or Python based Web application implement… Continue reading How to implement client side encryption for CalDav & CardDav content?
I have a very specific question.
A client verifies a server by taking the certificate and checking specific values and that the digital signature of the intermediate CA is correct (according to the public key stored on the clients compute… Continue reading Certificate Chain checking
I am at a student at a school which blocks the right click in Windows Explorer and the desktop, as well as on the taskbar. I don’t exactly understand why they do this, since most of the commands on the right click menu are also avaliable i… Continue reading Does Disabling Right Click In Windows Explorer Do Anything?
