Constructor Detail

TSAClientBouncyCastle

public TSAClientBouncyCastle(String url)

Creates an instance of a TSAClient that will use BouncyCastle.

Parameters: url String - Time Stamp Authority URL (i.e. "http://tsatest1.digistamp.com/TSA")

TSAClientBouncyCastle

public TSAClientBouncyCastle(String url, String username, String password)

Creates an instance of a TSAClient that will use BouncyCastle.

Parameters: url String - Time Stamp Authority URL (i.e. "http://tsatest1.digistamp.com/TSA") username String - user(account) name password String - password

TSAClientBouncyCastle

public TSAClientBouncyCastle(String url, String username, String password, int tokSzEstimate)

Constructor. Note the token size estimate is updated by each call, as the token size is not likely to change (as long as we call the same TSA using the same imprint length).

Parameters: url String - Time Stamp Authority URL (i.e. "http://tsatest1.digistamp.com/TSA") username String - user(account) name password String - password tokSzEstimate int - estimated size of received time stamp token (DER encoded)
