I'm thinking of implementing text encryption and decryption in my program using AES using key sharing thanks to MPC (the point is that the key should never be provided in full), however, all public libraries that I found offer this option only assuming that one member has the whole key and another plaintext. Does anyone know libraries that allow you to implement such a solution?

  • $\begingroup$ Note that requests for software libraries are off-topic. However asking which protocol would be best for the problem would be fully on-topic. $\endgroup$ – SEJPM Mar 11 '20 at 11:57
