Constructor Detail

ExtendedKeyUsage

public ExtendedKeyUsage(KeyPurposeId usage)

Base constructor, from a single KeyPurposeId.

Parameters:

usage - the keyPurposeId to be included.

ExtendedKeyUsage

public ExtendedKeyUsage(KeyPurposeId[] usages)

Base constructor, from multiple KeyPurposeIds.

Parameters:

usages - an array of KeyPurposeIds.

Method Detail

getInstance

public static ExtendedKeyUsage getInstance(ASN1TaggedObject obj,
                                           boolean explicit)

Return an ExtendedKeyUsage from the passed in tagged object.

Parameters:

obj - the tagged object containing the ExtendedKeyUsage

explicit - true if the tagged object should be interpreted as explicitly tagged, false if implicit.

Returns:

the ExtendedKeyUsage contained.

getInstance

public static ExtendedKeyUsage getInstance(java.lang.Object obj)

Return an ExtendedKeyUsage from the passed in object.

Parameters:

obj - an ExtendedKeyUsage, some form or encoding of one, or null.

Returns:

an ExtendedKeyUsage object, or null if null is passed in.

fromExtensions

public static ExtendedKeyUsage fromExtensions(Extensions extensions)

Retrieve an ExtendedKeyUsage for a passed in Extensions object, if present.

Parameters:

extensions - the extensions object to be examined.

Returns:

the ExtendedKeyUsage, null if the extension is not present.

hasKeyPurposeId

public boolean hasKeyPurposeId(KeyPurposeId keyPurposeId)

Return true if this ExtendedKeyUsage object contains the passed in keyPurposeId.

Parameters:

keyPurposeId - the KeyPurposeId of interest.

Returns:

true if the keyPurposeId is present, false otherwise.

getUsages

public KeyPurposeId[] getUsages()

Returns all extended key usages.

Returns:

An array with all key purposes.

size

public int size()

Return the number of KeyPurposeIds present in this ExtendedKeyUsage.

Returns:

the number of KeyPurposeIds

toASN1Primitive

public ASN1Primitive toASN1Primitive()

Return the ASN.1 primitive form of this object.

Specified by:

toASN1Primitive in interface ASN1Encodable

Specified by:

toASN1Primitive in class ASN1Object

Returns:

an ASN1Sequence.
