Boolean !Bool

Tag number: 0x01

Integer !Int64

Tag number: 0x02

OctetString !Bytes

Tag number: 0x04

BitString !Word8 !Bytes

Tag number: 0x03. Has padding bit count and raw bytes.

Null

Tag number: 0x05

ObjectIdentifier !Oid

Tag number: 0x06

Utf8String !ShortText

Tag number: 0x0C

PrintableString !ShortText

Tag number: 0x13

UtcTime !Int64

Tag number: 0x17. Number of seconds since the epoch. The following guidance is inspired by RFC 5280:

• A two-digit year greater than or equal to 50 is interpreted as 19XX, and a two-digit year less than 50 is intepreted as 20XX.
• Everything is converted to Zulu time zone. Unlike RFC 5280, we do not require Zulu, but we convert everything to it.
• When seconds are absent, we treat the timestamp as one where the seconds are zero. That is, we understand 2303252359Z as 2023-03-25T23:59:00Z.

Constructed !(SmallArray Value)

Constructed value contents in concatenation order. The class and tag are held in Value.

Unresolved !Bytes

Values that require information about interpreting application, context-specific, or private tag.
