All Implemented Interfaces:

ASN1Encodable, Encodable

public class SubjectPublicKeyInfo

extends ASN1Object

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

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

Constructor Summary

SubjectPublicKeyInfo(AlgorithmIdentifier algId, ASN1BitString publicKey)

SubjectPublicKeyInfo(AlgorithmIdentifier algId, ASN1Encodable publicKey)

SubjectPublicKeyInfo(AlgorithmIdentifier algId, byte[] publicKey)

SubjectPublicKeyInfo(ASN1Sequence seq)
Deprecated. use SubjectPublicKeyInfo.getInstance()

Method Summary

AlgorithmIdentifier	getAlgorithm()
AlgorithmIdentifier	getAlgorithmId() Deprecated. use getAlgorithm()
static SubjectPublicKeyInfo	getInstance(ASN1TaggedObject obj, boolean explicit)
static SubjectPublicKeyInfo	getInstance(java.lang.Object obj)
ASN1Primitive	getPublicKey() Deprecated. use parsePublicKey
ASN1BitString	getPublicKeyData() for when the public key is raw bits.
ASN1Primitive	parsePublicKey() for when the public key is an encoded object - if the bitstring can't be decoded this routine throws an IOException.
ASN1Primitive	toASN1Primitive() Produce an object suitable for an ASN1OutputStream.

SubjectPublicKeyInfo

public SubjectPublicKeyInfo(ASN1Sequence seq)

Deprecated. use SubjectPublicKeyInfo.getInstance()

Method Detail

getInstance

public static SubjectPublicKeyInfo getInstance(ASN1TaggedObject obj,
                                               boolean explicit)

getInstance

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

getAlgorithm

public AlgorithmIdentifier getAlgorithm()

getAlgorithmId

public AlgorithmIdentifier getAlgorithmId()

Deprecated. use getAlgorithm()

Returns:

alg ID.

parsePublicKey

public ASN1Primitive parsePublicKey()
                             throws java.io.IOException

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

Returns:

the public key as an ASN.1 primitive.

Throws:

java.io.IOException - - if the bit string doesn't represent a DER encoded object.

getPublicKey

public ASN1Primitive getPublicKey()
                           throws java.io.IOException

Deprecated. use parsePublicKey

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

Returns:

the public key as an ASN.1 primitive.

Throws:

java.io.IOException - - if the bit string doesn't represent a DER encoded object.

getPublicKeyData

public ASN1BitString getPublicKeyData()

for when the public key is raw bits.

Returns:

the public key as the raw bit string[]

toASN1Primitive

public ASN1Primitive toASN1Primitive()

Produce an object suitable for an ASN1OutputStream. SubjectPublicKeyInfo ::= SEQUENCE { algorithm AlgorithmIdentifier, publicKey BIT STRING }

Overrides:

toASN1Primitive in class ASN1Object

Following copied from class: org.bouncycastle.asn1.ASN1Object

Returns:

a primitive representation of this object.
