X509CRLSelector

open class X509CRLSelector : CRLSelector

kotlin.Any
↳	java.security.cert.X509CRLSelector

A CRLSelector that selects X509CRLs that match all specified criteria. This class is particularly useful when selecting CRLs from a CertStore to check revocation status of a particular certificate.

When first constructed, an X509CRLSelector has no criteria enabled and each of the get methods return a default value (null). Therefore, the match method would return true for any X509CRL. Typically, several criteria are enabled (by calling setIssuers or setDateAndTime, for instance) and then the X509CRLSelector is passed to CertStore.getCRLs or some similar method.

Please refer to RFC 5280: Internet X.509 Public Key Infrastructure Certificate and CRL Profile for definitions of the X.509 CRL fields and extensions mentioned below.

Concurrent Access

Unless otherwise specified, the methods defined in this class are not thread-safe. Multiple threads that need to access a single object concurrently should synchronize amongst themselves and provide the necessary locking. Multiple threads each manipulating separate objects need not synchronize.

X509CRLSelector

Added in API level 1

X509CRLSelector()

Creates an X509CRLSelector. Initially, no criteria are set so any X509CRL will match.

Public methods

addIssuer

Added in API level 1

open fun addIssuer(issuer: X500Principal!): Unit

Adds a name to the issuerNames criterion. The issuer distinguished name in the X509CRL must match at least one of the specified distinguished names.

This method allows the caller to add a name to the set of issuer names which X509CRLs may contain. The specified name is added to any previous value for the issuerNames criterion. If the specified name is a duplicate, it may be ignored.

Parameters
issuer	X500Principal!: the issuer as X500Principal

addIssuerName

Added in API level 1

open fun addIssuerName(name: ByteArray!): Unit

Adds a name to the issuerNames criterion. The issuer distinguished name in the X509CRL must match at least one of the specified distinguished names.

This method allows the caller to add a name to the set of issuer names which X509CRLs may contain. The specified name is added to any previous value for the issuerNames criterion. If the specified name is a duplicate, it may be ignored. If a name is specified as a byte array, it should contain a single DER encoded distinguished name, as defined in X.501. The ASN.1 notation for this structure is as follows.

The name is provided as a byte array. This byte array should contain a single DER encoded distinguished name, as defined in X.501. The ASN.1 notation for this structure appears in the documentation for setIssuerNames(java.util.Collection).

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

Parameters
name	ByteArray!: a byte array containing the name in ASN.1 DER encoded form

Exceptions
java.io.IOException	if a parsing error occurs

addIssuerName

Added in API level 1

open fun addIssuerName(name: String!): Unit

Denigrated, use addIssuer(javax.security.auth.x500.X500Principal) or addIssuerName(byte[]) instead. This method should not be relied on as it can fail to match some CRLs because of a loss of encoding information in the RFC 2253 String form of some distinguished names.

Adds a name to the issuerNames criterion. The issuer distinguished name in the X509CRL must match at least one of the specified distinguished names.

This method allows the caller to add a name to the set of issuer names which X509CRLs may contain. The specified name is added to any previous value for the issuerNames criterion. If the specified name is a duplicate, it may be ignored.

Parameters
name	String!: the name in RFC 2253 form

Exceptions
java.io.IOException	if a parsing error occurs

clone

Added in API level 1

open fun clone(): Any

Returns a copy of this object.

Return
Any	the copy

Exceptions
java.lang.CloneNotSupportedException	if the object's class does not support the Cloneable interface. Subclasses that override the clone method can also throw this exception to indicate that an instance cannot be cloned.

getCertificateChecking

Added in API level 1

open fun getCertificateChecking(): X509Certificate!

Returns the certificate being checked. This is not a criterion. Rather, it is optional information that may help a CertStore find CRLs that would be relevant when checking revocation for the specified certificate. If the value returned is null, then no such optional information is provided.

Return
X509Certificate!	the certificate being checked (or null)

See Also

• #setCertificateChecking

getDateAndTime

Added in API level 1

open fun getDateAndTime(): Date!

Returns the dateAndTime criterion. The specified date must be equal to or later than the value of the thisUpdate component of the X509CRL and earlier than the value of the nextUpdate component. There is no match if the X509CRL does not contain a nextUpdate component. If null, no dateAndTime check will be done.

Note that the Date returned is cloned to protect against subsequent modifications.

Return
Date!	the Date to match against (or null)

See Also

• #setDateAndTime

getIssuerNames

Added in API level 1

open fun getIssuerNames(): MutableCollection<Any!>!

Returns a copy of the issuerNames criterion. The issuer distinguished name in the X509CRL must match at least one of the specified distinguished names. If the value returned is null, any issuer distinguished name will do.

If the value returned is not null, it is a Collection of names. Each name is a String or a byte array representing a distinguished name (in RFC 2253 or ASN.1 DER encoded form, respectively). Note that the Collection returned may contain duplicate names.

If a name is specified as a byte array, it should contain a single DER encoded distinguished name, as defined in X.501. The ASN.1 notation for this structure is given in the documentation for setIssuerNames(java.util.Collection).

Note that a deep copy is performed on the Collection to protect against subsequent modifications.

Return
MutableCollection<Any!>!	a Collection of names (or null)

See Also

• #setIssuerNames

getIssuers

Added in API level 1

open fun getIssuers(): MutableCollection<X500Principal!>!

Returns the issuerNames criterion. The issuer distinguished name in the X509CRL must match at least one of the specified distinguished names. If the value returned is null, any issuer distinguished name will do.

If the value returned is not null, it is a unmodifiable Collection of X500Principals.

Return
MutableCollection<X500Principal!>!	an unmodifiable Collection of names (or null)

See Also

• #setIssuers

getMaxCRL

Added in API level 1

open fun getMaxCRL(): BigInteger!

Returns the maxCRLNumber criterion. The X509CRL must have a CRL number extension whose value is less than or equal to the specified value. If null, no maxCRLNumber check will be done.

Return
BigInteger!	the maximum CRL number accepted (or null)

getMinCRL

Added in API level 1

open fun getMinCRL(): BigInteger!

Returns the minCRLNumber criterion. The X509CRL must have a CRL number extension whose value is greater than or equal to the specified value. If null, no minCRLNumber check will be done.

Return
BigInteger!	the minimum CRL number accepted (or null)

match

Added in API level 1

open fun match(crl: CRL!): Boolean

Decides whether a CRL should be selected.

Parameters
crl	CRL!: the CRL to be checked

Return
Boolean	true if the CRL should be selected, false otherwise

setCertificateChecking

Added in API level 1

open fun setCertificateChecking(cert: X509Certificate!): Unit

Sets the certificate being checked. This is not a criterion. Rather, it is optional information that may help a CertStore find CRLs that would be relevant when checking revocation for the specified certificate. If null is specified, then no such optional information is provided.

Parameters
cert	X509Certificate!: the X509Certificate being checked (or null)

See Also

• #getCertificateChecking

setDateAndTime

Added in API level 1

open fun setDateAndTime(dateAndTime: Date!): Unit

Sets the dateAndTime criterion. The specified date must be equal to or later than the value of the thisUpdate component of the X509CRL and earlier than the value of the nextUpdate component. There is no match if the X509CRL does not contain a nextUpdate component. If null, no dateAndTime check will be done.

Note that the Date supplied here is cloned to protect against subsequent modifications.

Parameters
dateAndTime	Date!: the Date to match against (or null)

See Also

• #getDateAndTime

setIssuerNames

Added in API level 1

open fun setIssuerNames(names: MutableCollection<*>!): Unit

Note: use setIssuers(java.util.Collection) instead or only specify the byte array form of distinguished names when using this method. See addIssuerName(java.lang.String) for more information.

Sets the issuerNames criterion. The issuer distinguished name in the X509CRL must match at least one of the specified distinguished names. If null, any issuer distinguished name will do.

This method allows the caller to specify, with a single method call, the complete set of issuer names which X509CRLs may contain. The specified value replaces the previous value for the issuerNames criterion.

The names parameter (if not null) is a Collection of names. Each name is a String or a byte array representing a distinguished name (in RFC 2253 or ASN.1 DER encoded form, respectively). If null is supplied as the value for this argument, no issuerNames check will be performed.

Note that the names parameter can contain duplicate distinguished names, but they may be removed from the Collection of names returned by the getIssuerNames method.

If a name is specified as a byte array, it should contain a single DER encoded distinguished name, as defined in X.501. The ASN.1 notation for this structure is as follows.

<code>Name ::= CHOICE {
    RDNSequence }
 
  RDNSequence ::= SEQUENCE OF RelativeDistinguishedName
 
  RelativeDistinguishedName ::=
    SET SIZE (1 .. MAX) OF AttributeTypeAndValue
 
  AttributeTypeAndValue ::= SEQUENCE {
    type     AttributeType,
    value    AttributeValue }
 
  AttributeType ::= OBJECT IDENTIFIER
 
  AttributeValue ::= ANY DEFINED BY AttributeType
  ....
  DirectoryString ::= CHOICE {
        teletexString           TeletexString (SIZE (1..MAX)),
