Constructor Details

Certificate

public Certificate()
The basic constructor. Object is special, because it has no superclass, so there is no call to super().

Method Details

equals

public boolean equals(Object other)
Tests if this certificate equals another.
Overrides:
equals in interface Object
Parameters:
other - The object to test.
Returns:
True if the certificates are equal.

getEncoded

public abstract byte[] getEncoded()
            throws CertificateEncodingException
Return the encoded form of this certificate.
Returns:
The encoded form.
Throws:
CertificateEncodingException - If the certificate could not be encoded.

getPublicKey

public abstract PublicKey getPublicKey()
Returns this certificate's public key.
Returns:
The public key.

hashCode

public int hashCode()
Computes a hash code for this certificate.
Overrides:
hashCode in interface Object
Returns:
The hash code.

toString

public abstract String toString()
Returns a printable representation of this certificate.
Overrides:
toString in interface Object
Returns:
The string.

verify

public abstract void verify(PublicKey key)
            throws CertificateException,
                   NoSuchAlgorithmException,
                   InvalidKeyException,
                   NoSuchProviderException,
                   SignatureException
Verifies the signature of this certificate.
Parameters:
key - The signer's public key.
Throws:
CertificateException -
NoSuchAlgorithmException - If the algorithm used to sign the certificate is not available.
InvalidKeyException - If the supplied key is not appropriate for the certificate's signature algorithm.
NoSuchProviderException -
SignatureException - If the signature could not be verified.

verify

public abstract void verify(PublicKey key,
                            String sigProvider)
            throws CertificateException,
                   NoSuchAlgorithmException,
                   InvalidKeyException,
                   NoSuchProviderException,
                   SignatureException
Verifies the signature of this certificate, using the specified security provider.
Parameters:
key - The signer's public key.
sigProvider - The name of the signature provider.
Throws:
CertificateException -
NoSuchAlgorithmException - If the algorithm used to sign the certificate is not available.
InvalidKeyException - If the supplied key is not appropriate for the certificate's signature algorithm.
NoSuchProviderException - If sigProvider is not the name of an installed provider.
SignatureException - If the signature could not be verified.
