Gets the certificates chain by alias. Always returns the first certificate if a certificate chain is found.

Parameters:

crypto - Crypto to lookup certificate.

alias - Alias name.

Returns:

X509 certificate object.

Throws:

TrustException - If an error occurred while retrieving the certificate or if no certificates are found for given alias.

getCertificatesByAlias

public static java.security.cert.X509Certificate[] getCertificatesByAlias(org.apache.ws.security.components.crypto.Crypto crypto,
                                                                          java.lang.String alias)

Gets the certificates chain by alias. If no certificates are found return an empty array.

Parameters:

crypto - Crypto to lookup certificate.

alias - Alias name.

Returns:

X509 certificates array.

Throws:

TrustException - If an error occurred while retrieving the certificate.
