This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
Our client requires us to use 3DES to encrypt the files that we send to them. They want us to create certificates with encryption algorithm as 3DES with the hashing & receipt algorithm being SHA1.
I havent done much in security, my idea is that 3DES is like RSA. Am i correct? If so are there any tools to create certificates using 3DES?
A little late to reply so I'm not sure if I'm much help to you.
3DES is not like RSA. 3DES is an example of what they call symmetric-key encryption whereas RSA is an example of what they call public-key encryption. Public-key is often very useful for solving the key-establishment problem and for signing and verifying signatures and can work alongside with symmetric-key encryption.
