ASN.1 Structured Types

Platform SDK: Cryptography

Structured types are those consisting of components. ASN.1 defines four structured types, all of which are relevant to PKCS:

SEQUENCE - an ordered collection of one or more types.
SEQUENCE OF - an ordered collection of zero or more occurrences of a given type.
SET - an unordered collection of one or more types.
SET OF - an unordered collection of zero or more occurrences of a given type.

The structured types can have optional components, possibly with default values.
