Method: OpenSSL::ASN1::Constructive#initialize

Defined in:

ossl_asn1.c

#OpenSSL::ASN1::Primitive.new(value[, tag, tagging, tag_class ]) ⇒ Primitive

value: is mandatory.

tag: optional, may be specified for tagged values. If no tag is specified, the UNIVERSAL tag corresponding to the Primitive sub-class is used by default.

tagging: may be used as an encoding hint to encode a value either explicitly or implicitly, see ASN1 for possible values.

tag_class: if tag and tagging are nil then this is set to :UNIVERSAL by default. If either tag or tagging are set then :CONTEXT_SPECIFIC is used as the default. For possible values please cf. ASN1.

Example

int = OpenSSL::ASN1::Integer.new(42)
zero_tagged_int = OpenSSL::ASN1::Integer.new(42, 0, :IMPLICIT)
private_explicit_zero_tagged_int = OpenSSL::ASN1::Integer.new(42, 0, :EXPLICIT, :PRIVATE)
