 public abstract String getModuleName()

Retrieve name of module

Returns:

name of module

 public abstract String getCAName()

Retrieve the name of the CA.

Returns:

name of CA

 public abstract String getUserDN()

Retrieve certificate designated name.

Returns:

distinguished name of subject

 public abstract String getRegLevel()

Retrieve the registration level of this certificate as a String

Returns:

registration level

 public abstract String getIdLevel()

Retrieve the identification level of this certificate as a String

Returns:

identification level

 public abstract long getSerialNo()

Retrieve this Certificates SerialNr, with which it is identified by the CA that issued this certificate.

Returns:

serial number of certificate

 public abstract CryptoKeyInfo getPublicKey()

Retrieve the Public Key certified by this certificate.

Returns:

certified public key

 public abstract Scope getScope()

Retrieve the scope for this Certificate. The scope is encoded by an integer and tells what the certificed key can be used for (e.g., signing or encryption). This service may return SCOPE_NYI meaning that the certificate contains no information about the scope.

Returns:

scope of certificate (possibly SCOPE_NYI)

 public abstract CertificateType getType()

Retrieve the type of Certificate. E.g., a certificate may certify a key or be an attribute certificate certifyin that a particular person has a particular right. Again this service may return TYPE_NYI

Returns:

type of certificate (possibly TYPE_NYI)

 public abstract Date getNotValidBefore()

Retrieve the Date before which this certificate isn't valid.

Returns:

Date before which this certificate isn't valid.

 public abstract Date getNotValidAfter()

Retrieve the Date after which this certificate isn't valid.

Returns:

Date after which this certificate isn't valid.

 public abstract Status getStatus()

Retrieve the status of the Certificate. If status isn't implemented, (like in SecuDE) Certificates are assumed to be valid if they exist. The status may tell, e.g., if the certificate has been revoked. It is encoded by an integer.

Returns:

status of certificate (may be STATUS_NYI)

 public abstract byte[] getCASign()

Retrieve signature for this certificate signed by the CA whose Distinguished Name is stored in the Certificate.

Returns:

the signature as a byte array

 public abstract Revocation getWhyRevoked()

Retrieve reason why this Certificate was revoked. Might change to a string later on. RCModules, that can't implement it yet can instead return REVOC_REASON_NYI.

Returns:

the reason why a certificate has been revoked (possibly REVOC_REASON_NYI)

 public abstract SignAlgorithm getSignatureID()

Retrieve the algorithm ID of the algorithm used to sign this Certificate with. The types should correspond to the possible types defined in the CryptoConstants class (RSA, DSA etc.)

Returns:

an integer encoding the algorithm used for making the signature

 public abstract HashingAlgorithm getHashID()

Retrieve the algorithm ID of the algorithm used to hash this Certificate with. The types should correspond to the possible types defined in the CryptoConstants class (MD2C, MD4, RIPE_MD, SHA etc.)

Returns:

an integer encoding the algorithm used for hashing the certificate before signing.

 public abstract void setCAName(String name)

Set the CA's name that issued this certificate.

Parameters:

: - CA's name.

 public abstract void setUserDN(String name)

Set certificate owners name.

Parameters:

: - users name.

 public abstract void setSerialNo(long serialNr)

Set this Certificates SerialNr, with which it is identified by the CA that issued this certificate.

Parameters:

new - serial number.

 public abstract void setPublicKey(CryptoKeyInfo newKey)

Set the Public Key certified with this certificate.

Parameters:

: - new Key.

 public abstract void setScope(Scope scope)

 public abstract void setType(CertificateType type)

Set the type of Certificate. This might be an empty method.

Parameters:

type - of certificate.

 public abstract void setNotValidBefore(Date notValidBefore)

Set the Date before which this certificate isn't valid.

Parameters:

start - date of certificates validity period.

 public abstract void setNotValidAfter(Date notValidAfter)

Set the Date after which this certificate isn't valid.

Parameters:

end - date of certificates validity period.

 public abstract void setStatus(Status status)

Set the status of the Certificate. If status isn't implemented, this might be an empty method. For future implementations of certificate-modules it should definitely be implemented.

Parameters:

status - of certificate.

 public abstract void setWhyRevoked(Revocation whyRevoked)

Set reason why this Certificate was revoked. Might change to a string later on.

 public abstract void setSignatureID(SignAlgorithm signatureID)

Set the algorithm ID of the algorithm used to sign this Certificate with. The types should correspond to the possible types defined in the CryptoConstants class (RSA, DSA etc.)

Parameters:

signature - algorithm ID.

See Also:

CryptoConstants

 public abstract void setHashID(HashingAlgorithm hashID)

Set the algorithm ID of the algorithm used to hash this Certificate with. The types should correspond to the possible types defined in the CryptoConstants class (MD2C, MD4, RIPE_MD, SHA etc.)

Parameters:

hashing - ID.

See Also:

CryptoConstants

 public abstract boolean verifyCertificate(CryptoKeyInfo trustedPK) throws CertificateException

verify certificates correctness (ie whether signature matches its contents).

Parameters:

s - trustedPK is the the public key which the signature is verified against.

Throws: CertificateException

if some error occurred while verifying.

 public abstract boolean sameCertificate(Certificate cert)

Desides whether two certificates should be considered equal.

Parameters:
