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.

ExtendedKeyUsage

public ExtendedKeyUsage(java.util.Vector usages)
Deprecated. use KeyPurposeId[] constructor.

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.
Overrides:
toASN1Primitive in class ASN1Object
Returns:
an ASN1Sequence.
