"DESCRIPTION"
Header "DESCRIPTION" \fBX509_get_pubkey() attempts to decode the public key for certificate x. If
successful it returns the public key as an \s-1EVP_PKEY\s0 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 not increment
the reference count of the returned \s-1EVP_PKEY\s0 so it must not be freed up
after use.
\fBX509_get_X509_PUBKEY() returns an internal pointer to the X509_PUBKEY structure which encodes the certificate of x. The returned value must not be freed up after use.
\fBX509_set_pubkey() attempts to set the public key for certificate x to \fBpkey. The key pkey should be freed up after use.
\fBX509_REQ_get_pubkey(), X509_REQ_get0_pubkey(), X509_REQ_set_pubkey() and \fBX509_REQ_get_X509_PUBKEY() are similar but operate on certificate request req.
"NOTES"
Header "NOTES" The first time a public key is decoded the \s-1EVP_PKEY\s0 structure is
cached in the certificate or certificate request itself. Subsequent calls
return the cached structure with its reference count incremented to
improve performance.
"RETURN VALUES"
Header "RETURN VALUES" \fBX509_get_pubkey(), X509_get0_pubkey(), X509_get_X509_PUBKEY(),
\fBX509_REQ_get_pubkey() and X509_REQ_get_X509_PUBKEY() return a public key or
\fB\s-1NULL\s0 if an error occurred.
\fBX509_set_pubkey() and X509_REQ_set_pubkey() return 1 for success and 0 for failure.
