NAME

       TS_VERIFY_CTX_set_certs, TS_VERIFY_CTS_set_certs - set certificates for TS response
       verification

SYNOPSIS

        #include <openssl/ts.h>

        STACK_OF(X509) *TS_VERIFY_CTX_set_certs(TS_VERIFY_CTX *ctx,
                                                STACK_OF(X509) *certs);
        STACK_OF(X509) *TS_VERIFY_CTS_set_certs(TS_VERIFY_CTX *ctx,
                                                STACK_OF(X509) *certs);

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. ctx is the verification context created in advance and certs is a stack of 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.

RETURN VALUES

       TS_VERIFY_CTX_set_certs() returns the stack of X509 certificates the user passes in via
       parameter certs.

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.
