class 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::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 ] )
