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.
