=pod =head1 NAME TS_VERIFY_CTX_set_certs, TS_VERIFY_CTS_set_certs - set certificates for TS response verification =head1 SYNOPSIS #include 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); =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 is the verification context created in advance and B is a stack of B 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 certificates the user passes in via parameter B. =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. =head1 COPYRIGHT Copyright 2019-2020 The OpenSSL Project Authors.
