|
||||
The ASN.1 string table is a unique global object.
|
||||
Each entry is of the type
|
||||
.Vt ASN1_STRING_TABLE
|
||||
and contains information about one NID object.
|
||||
Some entries are predefined according to RFC 3280 appendix A.1.

The entries are predefined according to RFC 5280 appendix A.1.

The function
|

.Fn ASN1_STRING_TABLE_add
|
||||
changes the existing entry for
|
||||
.Fa nid
|
||||
or, if there is none, allocates a new entry.
|
||||
The fields of the entry are overwritten with the function arguments
|
||||
of the same name.
|

If
|
||||
.Fa minsize
|
||||
or
|
||||
.Fa maxsize
|

is negative or
|

.Fa mask
|

is 0, that argument is ignored and the respective field remains unchanged,
|

or for a new entry, it is set to \-1, \-1, 0, or
|

.Dv STABLE_FLAGS_MALLOC ,
|
||||
respectively.
|
||||
.Pp
|
||||
The bits set in the
|
||||
.Fa flags
|
||||
argument are OR'ed into the existing field rather than overwriting it.
|
||||
The only useful flag is
|

.Dv STABLE_NO_MASK .

If it is set,

||||
.Xr ASN1_STRING_set_by_NID 3
|

skips applying the global mask that can be set with
|

.Xr ASN1_STRING_set_default_mask 3 .
|
||||
Otherwise, the table entry only accepts types
|
||||
permitted by both the global mask and the
|
||||
.Fa mask
|
||||
argument.
|
||||
Setting
|
||||
.Dv STABLE_FLAGS_MALLOC
|
||||
or any other bit in the
|
||||
.Fa mask
|
||||
argument has no effect.

The function

The function
|

.Fn ASN1_STRING_TABLE_cleanup
|

removes and frees all entries except the predefined ones
|

and restores the predefined ones to their default state.
|

If the
