Steve:
With respect to the use of email names now supported in certificates, what
set of characters are permitted and what "Syntax" is used in
SubjectAltName?
Full syntax follows.
AltName ::= CHOICE {
rfc822Name [0] IA5String,
dNSName [1] IA5String,
x400Address [2] ORAddress -- Imported from X.400 --,
privateName [3] INSTANCE OF PRIVATE-NAME }
PRIVATE-NAME ::= TYPE-IDENTIFIER
This extension is always non-critical. An implementation
which recognizes this extension is not required to be able
to process all alternatives of the CHOICE. If the
alternative used is not supported by the implementation, the
extension field is ignored.
Use of the TYPE-IDENTIFIER class is described in Annexes A
and C of ITU-T Rec. X.681 | ISO/IEC 8824-2.
