CTLOG_NEW(3) OpenSSL CTLOG_NEW(3)
NAME
CTLOG_new, CTLOG_new_from_base64, CTLOG_free, CTLOG_get0_name,
CTLOG_get0_log_id, CTLOG_get0_public_key - encapsulates information
about a Certificate Transparency log
SYNOPSIS
#include <openssl/ct.h>
CTLOG *CTLOG_new(EVP_PKEY *public_key, const char *name);
int CTLOG_new_from_base64(CTLOG ** ct_log,
const char *pkey_base64, const char *name);
void CTLOG_free(CTLOG *log);
const char *CTLOG_get0_name(const CTLOG *log);
void CTLOG_get0_log_id(const CTLOG *log, const uint8_t **log_id,
size_t *log_id_len);
EVP_PKEY *CTLOG_get0_public_key(const CTLOG *log);
DESCRIPTION
CTLOG_new() returns a new CTLOG that represents the Certificate
Transparency (CT) log with the given public key. A name must also be
provided that can be used to help users identify this log. Ownership of
the public key is transferred.
CTLOG_new_from_base64() also creates a new CTLOG, but takes the public
key in base64-encoded DER form and sets the ct_log pointer to point to
the new CTLOG. The base64 will be decoded and the public key parsed.
Regardless of whether CTLOG_new() or CTLOG_new_from_base64() is used,
it is the caller's responsibility to pass the CTLOG to CTLOG_free()
once it is no longer needed. This will delete it and, if created by
CTLOG_new(), the EVP_PKEY that was passed to it.
CTLOG_get0_name() returns the name of the log, as provided when the
CTLOG was created. Ownership of the string remains with the CTLOG.
CTLOG_get0_log_id() sets *log_id to point to a string containing that
log's LogID (see RFC 6962). It sets *log_id_len to the length of that
LogID. For a v1 CT log, the LogID will be a SHA-256 hash (i.e. 32 bytes
long). Ownership of the string remains with the CTLOG.
CTLOG_get0_public_key() returns the public key of the CT log. Ownership
of the EVP_PKEY remains with the CTLOG.
RETURN VALUES
CTLOG_new() will return NULL if an error occurs.
CTLOG_new_from_base64() will return 1 on success, 0 otherwise.
