encryption - algorithm for multiple digital signatures? -


Suppose I have a pack of data and I am sending data to 10 users. I want to add an attribute to this data, something like a digital signature. Each 10 users will have a different "key" when they apply their keys to this particular signature on the data packet, then it returns true or false returns, although they can not determine whether to use their key, whether other users Right or wrong

Even if the data packet is large:

in the data packet Encrypt the hash using the hash key for every user and attach the encrypted versions to the message.

Each user keeps the original packet (without signature), then confirms that hash matches their decrypted chuck.

This works for both symmetrical and public-private algorithms.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
