ECC encryption

[lehongzhang]

Hello everyone, please tell me how to use ECC encryption. Is there any guidance dome?

[astraw38]

Are you thinking of ECIES (and here)? Or ECDH then doing symmetric encryption?

What are you trying to encrypt and who is it for? ECC keys aren't used directly to encrypt something. Typically you are doing a key agreement to establish a shared symmetric key which is then used to encrypt the content.

hello , What I want to use is elliptical encryption and use it to encrypt a certain text. That text is on the HSM server. On Mon, Jan 29, 2024 at 11:35 PM Mike Gardiner ***@***.***> wrote:

You'd really need to determine what sort of encryption scheme you're wanting to do, and that is heavily determined by your use case or requirements. Are you trying to wrap something off the HSM? The links I provided will give you a great place to start.

I have got the text from HSM but I want to elliptical encrypt it
