    • TSAClientBouncyCastle

      public TSAClientBouncyCastle(String url)
      Deprecated.
      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)
      Deprecated.
      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)
      Deprecated.
      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)
