     2  Package x448 provides Diffie-Hellman functions as specified in RFC-7748.
     3  
     4  Validation of public keys.
     5  
     6  The Diffie-Hellman function, as described in RFC-7748 [1], works for any
     7  public key. However, if a different protocol requires contributory
     8  behaviour [2,3], then the public keys must be validated against low-order
     9  points [3,4]. To do that, the Shared function performs this validation
    10  internally and returns false when the public key is invalid (i.e., it
    11  is a low-order point).
