A name must also be provided that can be 26used to help users identify this log. Ownership of the public key is 27transferred. 28 29CTLOG_new_from_base64() also creates a new CTLOG, but takes the public key in 30base64-encoded DER form and sets the ct_log pointer to point to the new CTLOG. 31The base64 will be decoded and the public key parsed. 32 33Regardless of whether CTLOG_new() or CTLOG_new_from_base64() is used, it is the 34caller's responsibility to pass the CTLOG to CTLOG_free() once it is no longer 35needed. This will delete it and, if created by CTLOG_new(), the EVP_PKEY that 36was passed to it. 37 38CTLOG_get0_name() returns the name of the log, as provided when the CTLOG was 39created. Ownership of the string remains with the CTLOG. 40 41CTLOG_get0_log_id() sets *log_id to point to a string containing that log's 42LogID (see RFC 6962). It sets *log_id_len to the length of that LogID. For a 43v1 CT log, the LogID will be a SHA-256 hash (i.e. 32 bytes long). Ownership of 44the string remains with the CTLOG. 45 46CTLOG_get0_public_key() returns the public key of the CT log. Ownership of the 47EVP_PKEY remains with the CTLOG. 48 49=head1 RETURN VALUES 50 51CTLOG_new() will return NULL if an error occurs. 52 53CTLOG_new_from_base64() will return 1 on success, 0 otherwise. 54 55=head1 SEE ALSO 56 57L<ct(7)> 58 59=head1 HISTORY 60 61These functions were added in OpenSSL 1.1.0. 62 63=head1 COPYRIGHT 64 65Copyright 2016 The OpenSSL Project Authors.
