.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "EVP_PKEY_ASN1_GET_COUNT 3" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
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 Header "SYNOPSIS" .Vb 1 #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); .Ve Header "DESCRIPTION" \fBEVP_PKEY_asn1_count() returns a count of the number of public key \s-1ASN.1\s0 methods available: it includes standard methods and any methods added by the application.

\fBEVP_PKEY_asn1_get0() returns the public key \s-1ASN.1\s0 method idx. The value of idx must be between zero and EVP_PKEY_asn1_get_count() \- 1.

\fBEVP_PKEY_asn1_find() looks up the \s-1EVP_PKEY_ASN1_METHOD\s0 with \s-1NID\s0 \fBtype. If pe isn't \s-1NULL\s0, then it will look up an engine implementing a \fB\s-1EVP_PKEY_ASN1_METHOD\s0 for the \s-1NID\s0 type and return that instead, and also set *pe to point at the engine that implements it.

\fBEVP_PKEY_asn1_find_str() looks up the \s-1EVP_PKEY_ASN1_METHOD\s0 with \s-1PEM\s0 type string str. Just like EVP_PKEY_asn1_find(), if pe isn't \s-1NULL\s0, then it will look up an engine implementing a \s-1EVP_PKEY_ASN1_METHOD\s0 for the \s-1NID\s0 \fBtype and return that instead, and also set *pe to point at the engine that implements it.

\fBEVP_PKEY_asn1_get0_info() returns the public key \s-1ID,\s0 base public key \s-1ID\s0 (both NIDs), any flags, the method description and \s-1PEM\s0 type string associated with the public key \s-1ASN.1\s0 method *ameth.

\fBEVP_PKEY_asn1_count(), EVP_PKEY_asn1_get0(), EVP_PKEY_asn1_find() and \fBEVP_PKEY_asn1_find_str() are not thread safe, but as long as all \fB\s-1EVP_PKEY_ASN1_METHOD\s0 objects are added before the application gets threaded, using them is safe. See EVP_PKEY_asn1_add0\|(3).

Header "RETURN VALUES" \fBEVP_PKEY_asn1_count() returns the number of available public key methods.

\fBEVP_PKEY_asn1_get0() return a public key method or \s-1NULL\s0 if idx is out of range.

\fBEVP_PKEY_asn1_get0_info() returns 0 on failure, 1 on success.
