All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`PublicKey`	`getPublicKey()`	Gets the public key from this certificate.
`short`	`getType()`	Gets the type of this certificate
`boolean`	`verify(PublicKey pubKey)`	Verifies that this certificate was signed using the private key that corresponds to the specified public key.

- Method Detail
  - getType
```
short getType()
```
    Gets the type of this certificate
    
    Returns:
    
    the certificate type.

PublicKey getPublicKey()
                throws CryptoException
```
    Gets the public key from this certificate.
    
    Returns:
    
    the public key. It may be null if a CertificateParser.KeyHandler filter has been applied when the certificate was built and null was returned at that time.
    
    Throws:
    
    CryptoException - with CryptoException.NO_SUCH_ALGORITHM value if a certificate public key is not supported
  - verify
```
boolean verify(PublicKey pubKey)
        throws CryptoException,
               CertificateException
```
    Verifies that this certificate was signed using the private key that corresponds to the specified public key. No other checks are performed.
    In addition to returning a boolean result, this method sets the result in an internal state which can be rechecked using assertion methods of the SensitiveResult class, if supported by the platform.
    Parameters:
    
    pubKey - the public key used to carry out the verification.
    
    Returns:
    
    true if the signature verifies, false otherwise.
    
    Throws:
    
    CryptoException - with the following reasons code:
    
    CryptoException.NO_SUCH_ALGORITHM if the signature algorithm is not supported
    CryptoException.ILLEGAL_VALUE if the key object is inconsistent with the signature
    CryptoException.UNINITIALIZED_KEY if the key object is not initialized.
    
    CertificateException - with the following reasons code: CertificateException.MISSING_DATA if the certificate is missing data to complete the verification.
    
    In the case of a certificate of type CertificateParser.TYPE_X509_DER it means that one of the fields X509Certificate.FIELD_CERTIFICATE_SIGNATURE_ALG or X509Certificate.FIELD_CERTIFICATE_SIGNATURE is missing.
