=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The Time-Stamp Protocol (TSP) is defined by RFC 3161. TSP is a protocol used to
|
||
|
|
provide long term proof of the existence of a certain datum before a particular
|
||
|
|
time. TSP defines a Time Stamping Authority (TSA) and an entity who shall make
|
||
|
|
requests to the TSA. Usually the TSA is denoted as the server side and the
|
||
|
|
requesting entity is denoted as the client.
|
||
|
|
|
||
|
|
In TSP, when a server is sending a response to a client, the server normally
|
||
|
|
needs to sign the response data - the TimeStampToken (TST) - with its private
|
||
|
|
key. Then the client shall verify the received TST by the server's certificate
|
||
|
|
chain.
|
||
|
|
|
||
|
|
TS_VERIFY_CTX_set_certs() is used to set the server's certificate chain when
|
||
|
|
verifying a TST. B<ctx> is the verification context created in advance and
|
||
|
|
B<certs> is a stack of B<X509> certificates.
|
||
|
|
|
||
|
|
TS_VERIFY_CTS_set_certs() is a misspelled version of TS_VERIFY_CTX_set_certs()
|
||
|
|
which takes the same parameters and returns the same result.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
TS_VERIFY_CTX_set_certs() returns the stack of B<X509> certificates the user
|
||
|
|
passes in via parameter B<certs>.
|
||
|
|
|
||
|
|
=head1 HISTORY
|
||
|
|
|
||
|
|
The spelling of TS_VERIFY_CTX_set_certs() was corrected in OpenSSL 3.0.0.
|
||
|
|
The misspelled version TS_VERIFY_CTS_set_certs() has been retained for
|
||
|
|
compatibility reasons, but it is deprecated in OpenSSL 3.0.0.
