EVP_PKEY_ASN1_GET_COUNT(3)          OpenSSL         EVP_PKEY_ASN1_GET_COUNT(3)
NAME
       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
SYNOPSIS
        #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);
DESCRIPTION
       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).
RETURN VALUES
       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.
