|X509_GET_PUBKEY(3)||Library Functions Manual||X509_GET_PUBKEY(3)|
X509_get_pubkey() attempts to decode the public key for certificate x. If successful it returns the public key as an 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 that it does not increment the reference count of the returned EVP_PKEY, so it must not be freed up after use.
X509_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.
X509_get_X509_PUBKEY() is implemented
as a macro.
X509_set_pubkey() attempts to set the
public key for certificate x to
pkey. The key pkey should be
freed up after use.
X509_REQ_set_pubkey() are similar but operate on
certificate request req.
The first time a public key is decoded, the 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.
X509_REQ_get_pubkey() return a public key or
NULLif an error occurred.
X509_REQ_set_pubkey() return 1 for success or 0 for
