OpenSSL::ASN1::Constructive

The parent class for all constructed encodings. The value attribute of a Constructive is always an Array. Attributes are the same as for ASN1Data, with the addition of tagging.

SET and SEQUENCE

Most constructed encodings come in the form of a SET or a SEQUENCE. These encodings are represented by one of the two sub-classes of Constructive:

• OpenSSL::ASN1::Set

• OpenSSL::ASN1::Sequence

Please note that tagged sequences and sets are still parsed as instances of ASN1Data. Find further details on tagged values there.

Example - constructing a SEQUENCE

int = OpenSSL::ASN1::Integer.new(1)
str = OpenSSL::ASN1::PrintableString.new('abc')
sequence = OpenSSL::ASN1::Sequence.new( [ int, str ] )

Example - constructing a SET

int = OpenSSL::ASN1::Integer.new(1)
str = OpenSSL::ASN1::PrintableString.new('abc')
set = OpenSSL::ASN1::Set.new( [ int, str ] )
