EVP_PKEY_asn1_find, EVP_PKEY_asn1_find_str, EVP_PKEY_asn1_get_count, EVP_PKEY_asn1_get0, EVP_PKEY_asn1_get0_info - enumerate public key ASN.1 methods
#include <openssl/evp.h>
int EVP_PKEY_asn1_get_count(void); const EVP_PKEY_ASN1_METHOD *EVP_PKEY_asn1_get0(int idx); const EVP_PKEY_ASN1_METHOD *EVP_PKEY_asn1_find(ENGINE **pe, int type); const EVP_PKEY_ASN1_METHOD *EVP_PKEY_asn1_find_str(ENGINE **pe, const char *str, int len); int EVP_PKEY_asn1_get0_info(int *ppkey_id, int *pkey_base_id, int *ppkey_flags, const char **pinfo, const char **ppem_str, const EVP_PKEY_ASN1_METHOD *ameth);
EVP_PKEY_asn1_count()
returns a count of the number of public key
ASN.1 methods available: it includes standard methods and any methods
added by the application.
EVP_PKEY_asn1_get0()
returns the public key ASN.1 method idx.
The value of idx must be between zero and EVP_PKEY_asn1_get_count()
- 1.
EVP_PKEY_asn1_find()
looks up the EVP_PKEY_ASN1_METHOD with NID
type.
If pe isn't NULL, then it will look up an engine implementing a
EVP_PKEY_ASN1_METHOD for the NID type and return that instead,
and also set *pe to point at the engine that implements it.
EVP_PKEY_asn1_find_str()
looks up the EVP_PKEY_ASN1_METHOD with PEM
type string str.
Just like EVP_PKEY_asn1_find(), if pe isn't NULL, then it will
look up an engine implementing a EVP_PKEY_ASN1_METHOD for the NID
type and return that instead, and also set *pe to point at the
engine that implements it.
EVP_PKEY_asn1_get0_info()
returns the public key ID, base public key
ID (both NIDs), any flags, the method description and PEM type string
associated with the public key ASN.1 method *ameth.
EVP_PKEY_asn1_count(), EVP_PKEY_asn1_get0(), EVP_PKEY_asn1_find()
and
EVP_PKEY_asn1_find_str()
are not thread safe, but as long as all
EVP_PKEY_ASN1_METHOD objects are added before the application gets
threaded, using them is safe. See EVP_PKEY_asn1_add0(3).
EVP_PKEY_asn1_count()
returns the number of available public key methods.
EVP_PKEY_asn1_get0()
return a public key method or NULL if idx is
out of range.
EVP_PKEY_asn1_get0_info()
returns 0 on failure, 1 on success.
