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.

public DERBitString

Returns:

the public key as the raw bit string...
getPublicKeyData()

for when the public key is raw bits.

public ASN1Primitive

Returns:

the public key as an ASN.1 primitive.
parsePublicKey()

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

public ASN1Primitive
toASN1Primitive()

Implements abstract org.bouncycastle.asn1.ASN1Object.toASN1Primitive.

Implements org.bouncycastle.asn1.ASN1Encodable.toASN1Primitive.

Produce an object suitable for an ASN1OutputStream.

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