DESCRIPTION

CTLOG_new() does the same thing as CTLOG_new_ex() but with the default library context and the default property query string.

CTLOG_new_from_base64_ex() 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. The CTLOG will be associated with the given library context libctx and property query string propq.

CTLOG_new_from_base64() does the same thing as CTLOG_new_from_base64_ex() except that the default library context and property query string are used.

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.
