Constructor Detail

PKCVerifier

public PKCVerifier()

This constructor creates a PKCVerifier.

Method Detail

getPKC

public java.util.Vector getPKC(byte typeInfo,
                               java.lang.String hashAlgorithmId,
                               byte[] info)

This method returns certificates matching search parameters. This returns a certificate vector coded in DER format.

Parameters:

typeInfo - byte (search information: (0 = SubjectPKC, 1 = BaseCertID, 2 = Hash Public Key Certificate)

hashAlgorithmId - String (OID hash algorithm ("sha1" or "md5"). If not, it is null)

info - byte[] (byte array corresponds the encoding information)

getPKC

public java.util.Hashtable getPKC(byte typeInfo,
                                  byte[] info)

This method returns certificates matching search parameters. This returns a hashtable that contains two vectors: - certificate vector = certificates coded in DER format. - certificate path vector = absolute certificate paths.

Parameters:

typeInfo - byte (search information: (0 = SubjectPKC, 1 = BaseCertID, 2 = Hash Public Key)

info - byte[] (byte array corresponds the encoding information)

isPKCValid

public int isPKCValid(byte typeInfo,
                      java.lang.String hashAlgorithmId,
                      byte[] info)

This method validates a certificate matching search parameters.

Specified by:

isPKCValid in interface IPKCVerifier

Returns:

0: not valid

isPKCValid

public int isPKCValid(java.lang.String path)

This method validates a certificate from a specific path.

isPKCValid

public boolean isPKCValid(CertBean cb)

This method validates a certificate from a certificate bean.

Specified by:

isPKCValid in interface IPKCVerifier

isTrusted

public int isTrusted(byte typeInfo,
                     java.lang.String hashAlgorithmId,
                     byte[] info,
                     float trustThreshold)

This method evaluates the user's trustworthiness from a trust threshold.

Specified by:

isTrusted in interface IPKCVerifier

isTrusted

public boolean isTrusted(CertBean cb,
                         float trustThreshold)

This method evaluates the user's trustworthiness from a trust threshold.

Specified by:

isTrusted in interface IPKCVerifier

getTrustValue

public float getTrustValue(byte typeInfo,
                           java.lang.String hashAlgorithmId,
                           byte[] info)

This method returns the trust value associatted to a user.

Specified by:

getTrustValue in interface IPKCVerifier

getValidityPeriod

public java.lang.String[] getValidityPeriod()

This method returns the validity period of the certificate.

Specified by:

getValidityPeriod in interface IPKCVerifier

getErrorCode

public int getErrorCode()

This method returns the error code.

Specified by:

getErrorCode in interface IPKCVerifier
