Class SubjectPublicKeyInfo

public class SubjectPublicKeyInfo extends ASN1Encodable

The object that contains the public key stored in a certficate.

The getEncoded() method in the public keys in the JCE produces a DER encoded one of these.

Constructor Summary
	SubjectPublicKeyInfo(AlgorithmIdentifier algId, DEREncodable publicKey)
	SubjectPublicKeyInfo(AlgorithmIdentifier algId, byte[] publicKey)
	SubjectPublicKeyInfo(ASN1Sequence seq)

Method Summary
AlgorithmIdentifier	getAlgorithmId()
static SubjectPublicKeyInfo	getInstance(ASN1TaggedObject obj, boolean explicit)
static SubjectPublicKeyInfo	getInstance(Object obj)
DERObject	getPublicKey() for when the public key is an encoded object - if the bitstring can't be decoded this routine throws an IOException.
DERBitString	getPublicKeyData() for when the public key is raw bits...
DERObject	toASN1Object() Produce an object suitable for an ASN1OutputStream.

Constructor Detail

public SubjectPublicKeyInfo(AlgorithmIdentifier algId, DEREncodable publicKey)

public SubjectPublicKeyInfo(AlgorithmIdentifier algId, byte[] publicKey)

public SubjectPublicKeyInfo(ASN1Sequence seq)

public AlgorithmIdentifier getAlgorithmId()

public static SubjectPublicKeyInfo getInstance(ASN1TaggedObject obj, boolean explicit)

public static SubjectPublicKeyInfo getInstance(Object obj)

public DERObject getPublicKey()

for when the public key is an encoded object - if the bitstring can't be decoded this routine throws an IOException.

Throws: IOException - if the bit string doesn't represent a DER encoded object.

public DERBitString getPublicKeyData()

for when the public key is raw bits...

public DERObject toASN1Object()

Produce an object suitable for an ASN1OutputStream.
