A name must also be provided that can be used to help users identify this log. Ownership of the public key is transferred. .PP \&\fBCTLOG_new_from_base64()\fR also creates a new \s-1CTLOG,\s0 but takes the public key in base64\-encoded \s-1DER\s0 form and sets the ct_log pointer to point to the new \s-1CTLOG.\s0 The base64 will be decoded and the public key parsed. .PP Regardless of whether \fBCTLOG_new()\fR or \fBCTLOG_new_from_base64()\fR is used, it is the caller's responsibility to pass the \s-1CTLOG\s0 to \fBCTLOG_free()\fR once it is no longer needed. This will delete it and, if created by \fBCTLOG_new()\fR, the \s-1EVP_PKEY\s0 that was passed to it. .PP \&\fBCTLOG_get0_name()\fR returns the name of the log, as provided when the \s-1CTLOG\s0 was created. Ownership of the string remains with the \s-1CTLOG.\s0 .PP \&\fBCTLOG_get0_log_id()\fR sets *log_id to point to a string containing that log's LogID (see \s-1RFC 6962\s0). It sets *log_id_len to the length of that LogID. For a v1 \s-1CT\s0 log, the LogID will be a \s-1SHA\-256\s0 hash (i.e. 32 bytes long). Ownership of the string remains with the \s-1CTLOG.\s0 .PP \&\fBCTLOG_get0_public_key()\fR returns the public key of the \s-1CT\s0 log. Ownership of the \&\s-1EVP_PKEY\s0 remains with the \s-1CTLOG.\s0 .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBCTLOG_new()\fR will return \s-1NULL\s0 if an error occurs. .PP \&\fBCTLOG_new_from_base64()\fR will return 1 on success, 0 otherwise. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBct\fR\|(7) .SH "HISTORY" .IX Header "HISTORY" These functions were added in OpenSSL 1.1.0. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2016 The OpenSSL Project Authors.
