to implement an automatic e-mail based TSA with L<procmail(1)>

a separate apache module. HTTP client support is provided by

+The file containing the last serial number of the TSA is not
locked when being read or written. This is a problem if more than one
instance of L<openssl(1)> is trying to create a time stamp
response at the same time. This is not an issue when using the apache
server module, it does proper locking.

CRYPTO_THREAD_run_once() can be used to perform one-time initialization.

B<CRYPTO_ONCE> that was statically initialized to the value

CRYPTO_THREAD_lock_frees() frees the provided B<lock>.

CRYPTO_atomic_add() atomically adds B<amount> to B<val> and returns the
result of the operation in B<ret>. B<lock> will be locked, unless atomic
operations are supported on the specific platform. Because of this, if a
determine this, an SCT's timestamp and signature must be verified.
