Constructor Details

SubjectKeyIdentifier

public SubjectKeyIdentifier(byte[] keyid)

SubjectKeyIdentifier

protected SubjectKeyIdentifier(ASN1OctetString keyid)

SubjectKeyIdentifier

public SubjectKeyIdentifier(SubjectPublicKeyInfo spki)

Deprecated.

Calculates the keyidentifier using a SHA1 hash over the BIT STRING from SubjectPublicKeyInfo as defined in RFC3280.

Parameters:

spki - the subject public key info.

Method Details

getInstance

public static SubjectKeyIdentifier getInstance(ASN1TaggedObject obj, boolean explicit)

getInstance

public static SubjectKeyIdentifier getInstance(Object obj)

fromExtensions

public static SubjectKeyIdentifier fromExtensions(Extensions extensions)

getKeyIdentifier

public byte[] getKeyIdentifier()

toASN1Primitive

public ASN1Primitive toASN1Primitive()

Specified by:

toASN1Primitive in interface ASN1Encodable

Specified by:

toASN1Primitive in class ASN1Object

createSHA1KeyIdentifier

public static SubjectKeyIdentifier createSHA1KeyIdentifier(SubjectPublicKeyInfo keyInfo)

Deprecated.

use org.bouncycastle.cert.X509ExtensionUtils.createSubjectKeyIdentifier

Return a RFC 3280 type 1 key identifier. As in:

 (1) The keyIdentifier is composed of the 160-bit SHA-1 hash of the
 value of the BIT STRING subjectPublicKey (excluding the tag,
 length, and number of unused bits).
 

Parameters:

keyInfo - the key info object containing the subjectPublicKey field.

Returns:

the key identifier.

createTruncatedSHA1KeyIdentifier

public static SubjectKeyIdentifier createTruncatedSHA1KeyIdentifier(SubjectPublicKeyInfo keyInfo)

Deprecated.

use org.bouncycastle.cert.X509ExtensionUtils.createTruncatedSubjectKeyIdentifier

Return a RFC 3280 type 2 key identifier. As in:

 (2) The keyIdentifier is composed of a four bit type field with
 the value 0100 followed by the least significant 60 bits of the
 SHA-1 hash of the value of the BIT STRING subjectPublicKey.
 

Parameters:

keyInfo - the key info object containing the subjectPublicKey field.

Returns:

the key identifier.
