39 EVP_PKEY_set1_RSA(), EVP_PKEY_set1_DSA(), EVP_PKEY_set1_DH() and
40 EVP_PKEY_set1_EC_KEY() set the key referenced by B<pkey> to B<key>.
42 EVP_PKEY_get1_RSA(), EVP_PKEY_get1_DSA(), EVP_PKEY_get1_DH() and
43 EVP_PKEY_get1_EC_KEY() return the referenced key in B<pkey> or
44 B<NULL> if the key is not of the correct type.
46 EVP_PKEY_get0_RSA(), EVP_PKEY_get0_DSA(), EVP_PKEY_get0_DH() and
47 EVP_PKEY_get0_EC_KEY() also return the referenced key in B<pkey> or
48 B<NULL> if the key is not of the correct type but the reference
49 count of the returned key is B<not> incremented and so must not
50 be freed up after use.
52 EVP_PKEY_assign_RSA(), EVP_PKEY_assign_DSA(), EVP_PKEY_assign_DH()
53 and EVP_PKEY_assign_EC_KEY() also set the referenced key to B<key>
54 however these use the supplied B<key> internally and so B<key>
55 will be freed when the parent B<pkey> is freed.
57 EVP_PKEY_type() returns the type of key corresponding to the value
58 B<type>. The type of a key can be obtained with
59 EVP_PKEY_type(pkey->type). The return value will be EVP_PKEY_RSA,
60 EVP_PKEY_DSA, EVP_PKEY_DH or EVP_PKEY_EC for the corresponding
61 key types or NID_undef if the key type is unassigned.
65 In accordance with the OpenSSL naming convention the key obtained
66 from or assigned to the B<pkey> using the B<1> functions must be
67 freed as well as B<pkey>.
69 EVP_PKEY_assign_RSA(), EVP_PKEY_assign_DSA(), EVP_PKEY_assign_DH()
70 and EVP_PKEY_assign_EC_KEY() are implemented as macros.
74 EVP_PKEY_set1_RSA(), EVP_PKEY_set1_DSA(), EVP_PKEY_set1_DH() and
75 EVP_PKEY_set1_EC_KEY() return 1 for success or 0 for failure.
77 EVP_PKEY_get1_RSA(), EVP_PKEY_get1_DSA(), EVP_PKEY_get1_DH() and
78 EVP_PKEY_get1_EC_KEY() return the referenced key or B<NULL> if
81 EVP_PKEY_assign_RSA(), EVP_PKEY_assign_DSA(), EVP_PKEY_assign_DH()
82 and EVP_PKEY_assign_EC_KEY() return 1 for success and 0 for failure.
