add a given extension field for the standard extensions tag
The value parameter becomes the contents of the octet string associated
with the extension.
Initialise the builder using the subject from the passed in issuerCert as the issuer, as well as
passing through and converting the other objects provided.
Finder which is used to look up the algorithm identifiers representing the encryption algorithms that
are associated with a particular signature algorithm.
Create a padder to so that padded output will always be at least
length bytes long, using the passed in source of randomness to
provide the random material for the padder.

If the passed in flag is true, the signer signature will be based on the data, not
a collection of signed attributes, and no signed attributes will be included.

Basic Constructor - set up a calculator based on signerInfoGen with a ESSCertID calculated from
the signer's associated certificate using the sha1DigestCalculator.
Validate the timestamp request, checking the digest to see if it is of an
accepted type and whether it is of the correct length for the algorithm specified.
