TrustAnchor (Java Platform SE 8 ) (original) (raw)

Creates an instance of TrustAnchor with the specifiedX509Certificate and optional name constraints, which are intended to be used as additional constraints when validating an X.509 certification path.

The name constraints are specified as a byte array. This byte array should contain the DER encoded form of the name constraints, as they would appear in the NameConstraints structure defined inRFC 3280 and X.509. The ASN.1 definition of this structure appears below.

  NameConstraints ::= SEQUENCE {
       permittedSubtrees       [0]     GeneralSubtrees OPTIONAL,
       excludedSubtrees        [1]     GeneralSubtrees OPTIONAL }

  GeneralSubtrees ::= SEQUENCE SIZE (1..MAX) OF GeneralSubtree

  GeneralSubtree ::= SEQUENCE {
       base                    GeneralName,
       minimum         [0]     BaseDistance DEFAULT 0,
       maximum         [1]     BaseDistance OPTIONAL }

  BaseDistance ::= INTEGER (0..MAX)

  GeneralName ::= CHOICE {
       otherName                       [0]     OtherName,
       rfc822Name                      [1]     IA5String,
       dNSName                         [2]     IA5String,
       x400Address                     [3]     ORAddress,
       directoryName                   [4]     Name,
       ediPartyName                    [5]     EDIPartyName,
       uniformResourceIdentifier       [6]     IA5String,
       iPAddress                       [7]     OCTET STRING,
       registeredID                    [8]     OBJECT IDENTIFIER}
 

Note that the name constraints byte array supplied is cloned to protect against subsequent modifications.
