Digital Signatures

[Bakedgoods]

Has anyone used/implemented any digital signature systems?

If you have, what software do you use and what exactly did you use it for?

I used GPGKeys at Uni for a module on Internet Security. We used it to gain an understanding of what digital keys were and how to sign emails and documents to each other.

We also used it to sign, encrypt and submit our coursework to the Professor taking us.

I used a C++ library called Crypto++ for work which has just about every encryption and signuture algorithm that you'd ever want to use!

I am using it at work for the licencing mechanism on our software (or rather, as part of) i use ECC for encryption with an RSA signiture.

The software clients see will be able to decrypt and verify the data, and since we hold the private keys no one will be able to generate data which will correctly decrypt and verify.
