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).
