RecipientKeyAlgorithm Property

This property holds the algorithm associated with the key.

Syntax

ecccontrol.RecipientKeyAlgorithm[=integer]

Possible Values

  eaSecp256r1(0), 
  eaSecp384r1(1), 
  eaSecp521r1(2), 
  eaEd25519(3), 
  eaEd448(4), 
  eaX25519(5), 
  eaX448(6), 
  eaSecp160k1(7), 
  eaSecp192k1(8), 
  eaSecp224k1(9), 
  eaSecp256k1(10)

Default Value

0

Remarks

This property holds the algorithm associated with the key. Possible values are:

  • 0 (eaSecp256r1)
  • 1 (eaSecp384r1)
  • 2 (eaSecp521r1)
  • 3 (eaEd25519)
  • 4 (eaEd448)
  • 5 (eaX25519)
  • 6 (eaX448)
  • 7 (eaSecp160k1)
  • 8 (eaSecp192k1)
  • 9 (eaSecp224k1)
  • 10 (eaSecp256k1)

When assigning a key using the PEM formatted RecipientKeyPrivateKey and RecipientKeyPublicKey the RecipientKeyAlgorithm property will be automatically updated with the key algorithm.

When assigning a key using the raw key parameters (RecipientKeyK, RecipientKeyRx, and RecipientKeyRy for NIST or RecipientKeyXPk, and RecipientKeyXSk for Curve25519/Curve448) the RecipientKeyAlgorithm property must be set manually to the key algorithm.
