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