11.2. KDF Identifiers​

The "HPKE KDF Identifiers" registry lists identifiers for key derivation functions 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
  • KDF: The name of the algorithm
  • Nh: The output size of the Extract function in bytes
  • Reference: Where this algorithm is defined

Initial contents: Provided in Table 3
