What is a cryptographic accelerator?
Could you please explain what exactly a cryptographic accelerator is? I'm curious to know how it differs from traditional computing methods in terms of functionality and efficiency. Additionally, could you elaborate on the role of cryptographic accelerators in the broader context of cryptocurrency and finance? It would also be helpful if you could provide some examples of how they are being used in practical applications today. Finally, do cryptographic accelerators pose any security risks or challenges that need to be addressed?
