Return the next working key inheriting DSA parameters if necessary.

This methods inherits DSA parameters from the indexed certificate or previous certificates in the certificate chain to the returned PublicKey. The list is searched upwards, meaning the end certificate is at position 0 and previous certificates are following.

If the indexed certificate does not contain a DSA key this method simply returns the public key. If the DSA key already contains DSA parameters the key is also only returned.

Parameters:

certs - The certification path.

index - The index of the certificate which contains the public key which should be extended with DSA parameters.

Returns:

The public key of the certificate in list position index extended with DSA parameters if applicable.

Throws:

java.security.cert.CertPathValidatorException - if DSA parameters cannot be inherited.
