6 EVP_PKEY_asn1_find_str,

10 - enumerate public key ASN.1 methods
14 #include <openssl/evp.h>
16 int EVP_PKEY_asn1_get_count(void);
17 const EVP_PKEY_ASN1_METHOD *EVP_PKEY_asn1_get0(int idx);
18 const EVP_PKEY_ASN1_METHOD *EVP_PKEY_asn1_find(ENGINE **pe, int type);
19 const EVP_PKEY_ASN1_METHOD *EVP_PKEY_asn1_find_str(ENGINE **pe,
20 const char *str, int len);
21 int EVP_PKEY_asn1_get0_info(int *ppkey_id, int *pkey_base_id,
22 int *ppkey_flags, const char **pinfo,
23 const char **ppem_str,
24 const EVP_PKEY_ASN1_METHOD *ameth);
28 EVP_PKEY_asn1_count() returns a count of the number of public key
29 ASN.1 methods available: it includes standard methods and any methods
30 added by the application.
32 EVP_PKEY_asn1_get0() returns the public key ASN.1 method B<idx>.
33 The value of B<idx> must be between zero and EVP_PKEY_asn1_get_count()
36 EVP_PKEY_asn1_find() looks up the B<EVP_PKEY_ASN1_METHOD> with NID
38 If B<pe> isn't B<NULL>, then it will look up an engine implementing a
39 B<EVP_PKEY_ASN1_METHOD> for the NID B<type> and return that instead,
40 and also set B<*pe> to point at the engine that implements it.
42 EVP_PKEY_asn1_find_str() looks up the B<EVP_PKEY_ASN1_METHOD> with PEM
44 Just like EVP_PKEY_asn1_find(), if B<pe> isn't B<NULL>, then it will
45 look up an engine implementing a B<EVP_PKEY_ASN1_METHOD> for the NID
46 B<type> and return that instead, and also set B<*pe> to point at the
47 engine that implements it.
49 EVP_PKEY_asn1_get0_info() returns the public key ID, base public key
50 ID (both NIDs), any flags, the method description and PEM type string
51 associated with the public key ASN.1 method B<*ameth>.
53 EVP_PKEY_asn1_count(), EVP_PKEY_asn1_get0(), EVP_PKEY_asn1_find() and
54 EVP_PKEY_asn1_find_str() are not thread safe, but as long as all
55 B<EVP_PKEY_ASN1_METHOD> objects are added before the application gets
56 threaded, using them is safe. See L<EVP_PKEY_asn1_add0(3)>.
60 EVP_PKEY_asn1_count() returns the number of available public key methods.
62 EVP_PKEY_asn1_get0() return a public key method or B<NULL> if B<idx> is
65 EVP_PKEY_asn1_get0_info() returns 0 on failure, 1 on success.
