NE_SSL_CERT_READ(3) neon API reference NE_SSL_CERT_READ(3)

NAME

ne_ssl_cert_read, ne_ssl_cert_write, ne_ssl_cert_import,
ne_ssl_cert_export - functions to read or write certificates to and
from files or strings

SYNOPSIS

#include <ne_ssl.h>

ne_ssl_certificate *ne_ssl_cert_read(const char *filename);

int ne_ssl_cert_write(const ne_ssl_certificate *cert,
const char *filename);

ne_ssl_certificate *ne_ssl_cert_import(const char *data);

char *ne_ssl_cert_export(const ne_ssl_certificate *cert);

DESCRIPTION

The ne_ssl_cert_write function writes a certificate to a file using
the PEM encoding. The ne_ssl_cert_export function returns a
base64-encoded NUL-terminated string representing the certificate.
This string is malloc-allocated and should be destroyed using free by
the caller.

The ne_ssl_cert_read function reads a certificate from a PEM-encoded
file, and returns a certificate object. The ne_ssl_cert_import
function returns a certificate object from a base64-encoded string,
data, as returned by ne_ssl_cert_export. The certificate object
returned by these functions should be destroyed using
ne_ssl_cert_free after use.

RETURN VALUE

ne_ssl_cert_read returns NULL if a certificate could not be read from
the file. ne_ssl_cert_write returns non-zero if the certificate
could not be written to the file. ne_ssl_cert_export always returns
a NUL-terminated string, and never NULL. ne_ssl_cert_import returns
NULL if the string was not a valid base64-encoded certificate.

ENCODING FORMATS

The string produced by ne_ssl_cert_export is the base64 encoding of
the DER representation of the certificate. The file written by
ne_ssl_cert_write uses the PEM format: this is the base64 encoding of
the DER representation with newlines every 64 characters, and start
and end marker lines.
