=head1 SYNOPSIS
|
|
|
|
#include <openssl/x509.h>
|
|
|
|
EVP_PKEY *X509_get_pubkey(X509 *x);
|
|
EVP_PKEY *X509_get0_pubkey(X509 *x);
|
|
int X509_set_pubkey(X509 *x, EVP_PKEY *pkey);
|
|
X509_PUBKEY *X509_get_X509_PUBKEY(X509 *x);
|
|
|
|
EVP_PKEY *X509_REQ_get_pubkey(X509_REQ *req);
|
|
int X509_REQ_set_pubkey(X509_REQ *x, EVP_PKEY *pkey);
|
|
X509_PUBKEY *X509_REQ_get_X509_PUBKEY(X509_REQ *x);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
X509_get_pubkey() attempts to decode the public key for certificate B<x>. If
|
|
successful it returns the public key as an B<EVP_PKEY> pointer with its
|
|
reference count incremented: this means the returned key must be freed up
|
|
after use. X509_get0_pubkey() is similar except it does B<not> increment
|
|
the reference count of the returned B<EVP_PKEY> so it must not be freed up
|
|
after use.
|
|
|
|
X509_get_X509_PUBKEY() returns an internal pointer to the B<X509_PUBKEY>
|
|
structure which encodes the certificate of B<x>. The returned value
|
|
must not be freed up after use.
|
|
|
|
X509_set_pubkey() attempts to set the public key for certificate B<x> to
|
|
B<pkey>. The key B<pkey> should be freed up after use.
|
|
|
|
X509_REQ_get_pubkey(), X509_REQ_set_pubkey() and X509_REQ_get_X509_PUBKEY()
|
|
are similar but operate on certificate request B<req>.
|
|
|
|
=head1 NOTES
|
|
|
|
The first time a public key is decoded the B<EVP_PKEY> structure is
|
|
cached in the certificate or certificate request itself. Subsequent calls
|
|
return the cached structure with its reference count incremented to
|
|
improve performance.
|
|

|
=head1 RETURN VALUES
|
|
|
|
X509_get_pubkey(), X509_get0_pubkey(), X509_get_X509_PUBKEY(),
|
|
X509_REQ_get_pubkey() and X509_REQ_get_X509_PUBKEY() return a public key or
|
|
B<NULL> if an error occurred.
|
|
|
|
X509_set_pubkey() and X509_REQ_set_pubkey() rerturn 1 for success and 0
|
|
for failure.
