11.1. KEM Identifiers

11.1. KEM Identifiers​

The "HPKE KEM Identifiers" registry lists identifiers for key encapsulation algorithms defined for use with HPKE. These identifiers are two-byte values, so the maximum possible value is 0xFFFF = 65535.

Template:

  • Value: The two-byte identifier for the algorithm
  • KEM: The name of the algorithm
  • Nsecret: The length in bytes of a KEM shared secret produced by the algorithm
  • Nenc: The length in bytes of an encoded encapsulated key produced by the algorithm
  • Npk: The length in bytes of an encoded public key for the algorithm
  • Nsk: The length in bytes of an encoded private key for the algorithm
  • Auth: A boolean indicating if this algorithm provides the AuthEncap()/AuthDecap() interface
  • Reference: Where this algorithm is defined
