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.
