Method Detail

verifyCertificate

public static java.lang.String verifyCertificate(java.security.cert.X509Certificate cert,
                                                 java.util.Collection<java.security.cert.CRL> crls,
                                                 java.util.Calendar calendar)

Verifies a single certificate.

Parameters:

cert - the certificate to verify

crls - the certificate revocation list or null

calendar - the date or null for the current date

Returns:

a String with the error description or null if no error

verifyCertificates

public static java.util.List<VerificationException> verifyCertificates(java.security.cert.Certificate[] certs,
                                                                       java.security.KeyStore keystore,
                                                                       java.util.Collection<java.security.cert.CRL> crls,
                                                                       java.util.Calendar calendar)

Verifies a certificate chain against a KeyStore.

Parameters:

certs - the certificate chain

keystore - the KeyStore

crls - the certificate revocation list or null

calendar - the date or null for the current date

Returns:

null if the certificate chain could be validated or a Object[]{cert,error} where cert is the failed certificate and error is the error message

verifyCertificates

Verifies a certificate chain against a KeyStore.

Parameters:

certs - the certificate chain

keystore - the KeyStore

calendar - the date or null for the current date

Returns:

null if the certificate chain could be validated or a Object[]{cert,error} where cert is the failed certificate and error is the error message
