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_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_from_base64() will return 1 on success, 0 otherwise.
