Example 2 with SignerCertPair

the class CryptoExtensions method findSignersByName.

/**
	 * Searches CMS signed data for a given email name.  Signed data may consist of multiple signatures either from the same subject of from multiple
	 * subjects. 
	 * @param signedData The signed data to search.
	 * @param name The name to search for in the list of signers.
	 * @param excludeNames A list of names to exclude from the list.  Because the search uses a simple "contains" search, it is possible for the name parameter
	 * to be a substring of what is requested.  The excludeNames contains a super string of the name to remove unwanted names from the returned list.  This parameter
	 * may be null;
	 * @return A colllection of pairs consisting of the singer's X509 certificated and signer information that matches the provided name.  Returns
	 * an empty collection if a signer matching the name cannot be found in the signed data.
