Class ChipAuthenticationPublicKeyInfo

java.lang.Object
  org.jmrtd.lds.SecurityInfo
      org.jmrtd.lds.ChipAuthenticationPublicKeyInfo

public class ChipAuthenticationPublicKeyInfo
extends SecurityInfo

A concrete SecurityInfo structure that stores chip authentication public key info, see EAC 1.11 specification. This data structure provides a Chip Authentication Public Key of the MRTD chip.

• The object identifier protocol SHALL identify the type of the public key (i.e. DH or ECDH).
• The sequence chipAuthenticationPublicKey SHALL contain the public key in encoded form.
• The integer keyId MAY be used to indicate the local key identifier. It MUST be used if the MRTD chip provides multiple public keys for Chip Authentication.
