Library Functions Manual

ASN1_STRING_TABLE_GET(3)

NAME

ASN1_STRING_TABLE_get — retrieve an entry from the global ASN.1 string table

SYNOPSIS

#include <openssl/asn1.h>

ASN1_STRING_TABLE *
ASN1_STRING_TABLE_get(int nid);

DESCRIPTION

The ASN.1 string table is a unique global object. Each entry is of the type ASN1_STRING_TABLE and contains information about one NID object. The entries are predefined according to RFC 5280 appendix A.1.

The upper bounds for the number of characters in various kinds of ASN1_STRING objects are:

object type	maxsize	symbolic constant
`NID_commonName`	64	`ub_common_name`
`NID_countryName`	2	—
`NID_givenName`	32768	`ub_name`
`NID_initials`	32768	`ub_name`
`NID_localityName`	128	`ub_locality_name`
`NID_name`	32768	`ub_name`
`NID_organizationName`	64	`ub_organization_name`
`NID_organizationalUnitName`	64	`ub_organization_unit_name`
`NID_pkcs9_emailAddress`	128	`ub_email_address`
`NID_serialNumber`	64	`ub_serial_number`
`NID_stateOrProvinceName`	128	`ub_state_name`
`NID_surname`	32768	`ub_name`

The function ASN1_STRING_TABLE_get() retrieves the entry for nid. If the STABLE_NO_MASK flag is set, ASN1_STRING_set_by_NID(3) skips applying the global mask that can be set with ASN1_STRING_set_default_mask(3).

RETURN VALUES

ASN1_STRING_TABLE_get() returns a valid ASN1_STRING_TABLE structure or NULL if nothing is found.

HISTORY

ASN1_STRING_TABLE_get() first appeared in OpenSSL 0.9.5 and has been available since OpenBSD 2.7.

BUGS

Most aspects of the semantics considerably differ from OpenSSL.

ub_email_address, which should really be called ub_emailaddress_length, was changed in RFC 5280 from 128 to 255 to match PKCS#9 (RFC 2985).
