<h1><a name="description">DESCRIPTION</a></h1>
|
||
|
<p>X509_get_pubkey() attempts to decode the public key for certificate <strong>x</strong>. If
|
||
|
successful it returns the public key as an <strong>EVP_PKEY</strong> 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 <strong>not</strong> increment
|
||
|
the reference count of the returned <strong>EVP_PKEY</strong> so it must not be freed up
|
||
|
after use.</p>
|
||
|
<p>X509_get_X509_PUBKEY() returns an internal pointer to the <strong>X509_PUBKEY</strong>
|
||
|
structure which encodes the certificate of <strong>x</strong>. The returned value
|
||
|
must not be freed up after use.</p>
|
||
|
<p>X509_set_pubkey() attempts to set the public key for certificate <strong>x</strong> to
|
||
|
<strong>pkey</strong>. The key <strong>pkey</strong> should be freed up after use.</p>
|
||
|
<p>X509_REQ_get_pubkey(), X509_REQ_get0_pubkey(), X509_REQ_set_pubkey() and
|
||
|
X509_REQ_get_X509_PUBKEY() are similar but operate on certificate request <strong>req</strong>.</p>

|

|
<p>The first time a public key is decoded the <strong>EVP_PKEY</strong> structure is
|
||
|
cached in the certificate or certificate request itself. Subsequent calls
|
||
|
return the cached structure with its reference count incremented to
|
||
|
improve performance.</p>
