.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "CTLOG_STORE_NEW 3ossl" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
CTLOG_STORE_new_ex, CTLOG_STORE_new, CTLOG_STORE_free, CTLOG_STORE_load_default_file, CTLOG_STORE_load_file - Create and populate a Certificate Transparency log list Header "SYNOPSIS" .Vb 1 #include <openssl/ct.h> \& CTLOG_STORE *CTLOG_STORE_new_ex(OSSL_LIB_CTX *libctx, const char *propq); CTLOG_STORE *CTLOG_STORE_new(void); void CTLOG_STORE_free(CTLOG_STORE *store); \& int CTLOG_STORE_load_default_file(CTLOG_STORE *store); int CTLOG_STORE_load_file(CTLOG_STORE *store, const char *file); .Ve Header "DESCRIPTION" A \s-1CTLOG_STORE\s0 is a container for a list of CTLOGs (Certificate Transparency logs). The list can be loaded from one or more files and then searched by LogID (see \s-1RFC 6962,\s0 Section 3.2, for the definition of a LogID).

\fBCTLOG_STORE_new_ex() creates an empty list of \s-1CT\s0 logs associated with the library context libctx and the property query string propq.

\fBCTLOG_STORE_new() does the same thing as CTLOG_STORE_new_ex() but with the default library context and property query string.

The \s-1CTLOG_STORE\s0 is then populated by CTLOG_STORE_load_default_file() or \fBCTLOG_STORE_load_file(). CTLOG_STORE_load_default_file() loads from the default file, which is named ct_log_list.cnf in \s-1OPENSSLDIR\s0 (see the output of \fBopenssl-version\|(1)). This can be overridden using an environment variable named \s-1CTLOG_FILE\s0. CTLOG_STORE_load_file() loads from a caller-specified file path instead. Both of these functions append any loaded \s-1CT\s0 logs to the \s-1CTLOG_STORE.\s0

The expected format of the file is:

.Vb 1 enabled_logs=foo,bar \& [foo] description = Log 1 key = <base64-encoded DER SubjectPublicKeyInfo here> \& [bar] description = Log 2 key = <base64-encoded DER SubjectPublicKeyInfo here> .Ve

Once a \s-1CTLOG_STORE\s0 is no longer required, it should be passed to \fBCTLOG_STORE_free(). This will delete all of the CTLOGs stored within, along with the \s-1CTLOG_STORE\s0 itself.

Header "NOTES" If there are any invalid \s-1CT\s0 logs in a file, they are skipped and the remaining valid logs will still be added to the \s-1CTLOG_STORE. A CT\s0 log will be considered invalid if it is missing a \*(L"key\*(R" or \*(L"description\*(R" field. Header "RETURN VALUES" Both CTLOG_STORE_load_default_file and CTLOG_STORE_load_file return 1 if all \s-1CT\s0 logs in the file are successfully parsed and loaded, 0 otherwise. Header "SEE ALSO" \fBct\|(7), \fBCTLOG_STORE_get0_log_by_id\|(3), \fBSSL_CTX_set_ctlog_list_file\|(3) Header "HISTORY" CTLOG_STORE_new_ex was added in OpenSSL 3.0. All other functions were added in OpenSSL 1.1.0. Header "COPYRIGHT" Copyright 2016-2020 The OpenSSL Project Authors. All Rights Reserved.
