How can I set my own key #433

Closed KwonDK closed 3 years ago

KwonDK commented 3 years ago

Hello, I want to set my own secret key, but the function GenSecKey() cannot provide this.

For example, I try to set my secret key like [1,0,1,0] according to BGV (context : p=17, r=1, m=8).

helib::Context context = helib::ContextBuilder<helib::BGV>() .m(m) .p(p) .r(r) .bits(bits) .c(c) .build() helib::SecKey secret_key(context); secret_key.GenSecKey();

I cannot input secret key [1,0,1,0] anywhere..

Does HElib support a secret key customizing?(like password) Is there any function that can provide a 'custom secret key'?

@KwonDK In HElib we don't support an API to customize keys like passwords. Key pairs are genearated based on the context parameters. Each key generation request generates a new key.

Please check the utilities provided in the utils directory.
