EVP_PKEY_asn1_get_count() returns 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 in the range from zero to
EVP_PKEY_asn1_get_count() - 1.
EVP_PKEY_asn1_find() looks up the method with NID type, which can be any of the values that EVP_PKEY_base_id(3) and EVP_PKEY_id(3) may return. If pe is not
NULL, it first looks for an engine implementing a method for the NID type. If one is found, *pe is set to that engine and the method from that engine is returned instead.
EVP_PKEY_asn1_find_str() looks up the method with PEM type string str. The PEM type strings supported by default are listed in the EVP_PKEY_base_id(3) manual page. Just like
EVP_PKEY_asn1_find(), if pe is not
NULL, methods from engines are preferred.
EVP_PKEY_asn1_get0_info() retrieves the public key ID as returned by EVP_PKEY_id(3), the base public key ID as returned by EVP_PKEY_base_id(3) (both NIDs), any flags, the method description, and the PEM type string associated with ameth.
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_get_count() returns the number of available public key methods.
EVP_PKEY_asn1_get0() returns a public key method or
NULLif idx is out of range.
EVP_PKEY_get0_asn1() returns the public key method used by pkey.
EVP_PKEY_asn1_get0_info() returns 1 on success or 0 on failure. EVP_PKEY_asn1_new(3), EVP_PKEY_base_id(3), EVP_PKEY_new(3) OpenBSD 4.9.
