Generic error class for all errors raised in ASN1 and any of the classes defined in it.

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 ] )

Infinite length primitive values

The only case where Constructive is used directly is for infinite length encodings of primitive values. These encodings are always constructed, with the contents of the value Array being either UNIVERSAL non-infinite length partial encodings of the actual value or again constructive encodings with infinite length (i.e. infinite length primitive encodings may be constructed recursively with another infinite length value within an already infinite length value). Each partial encoding must be of the same UNIVERSAL type as the overall encoding. The value of the overall encoding consists of the concatenation of each partial encoding taken in sequence. The value array of the outer infinite length value must end with a OpenSSL::ASN1::EndOfContent instance.

Please note that it is not possible to encode Constructive without the infinite_length attribute being set to true, use OpenSSL::ASN1::Sequence or OpenSSL::ASN1::Set in these cases instead.

Example - Infinite length OCTET STRING

partial1 = OpenSSL::ASN1::OctetString.new("\x01")
partial2 = OpenSSL::ASN1::OctetString.new("\x02")
inf_octets = OpenSSL::ASN1::Constructive.new( [ partial1,
                                                partial2,
                                                OpenSSL::ASN1::EndOfContent.new ],
                                              OpenSSL::ASN1::OCTET_STRING,
                                              nil,
                                              :UNIVERSAL )
# The real value of inf_octets is "\x01\x02", i.e. the concatenation
# of partial1 and partial2
inf_octets.infinite_length = true
der = inf_octets.to_der
asn1 = OpenSSL::ASN1.decode(der)
puts asn1.infinite_length # => true

This is the generic exception for OpenSSL::Engine related errors

Generic Exception class that is raised if an error occurs during an operation on an instance of OpenSSL::Netscape::SPKI.

OCSP error class.

An OpenSSL::OCSP::Response contains the status of a certificate check which is created from an OpenSSL::OCSP::Request.

An OpenSSL::OCSP::BasicResponse contains the status of a certificate check which is created from an OpenSSL::OCSP::Request. A BasicResponse is more detailed than a Response.

An OpenSSL::OCSP::SingleResponse represents an OCSP SingleResponse structure, which contains the basic information of the status of the certificate.

Generic Exception class that is raised if an error occurs during a computation.

Raised when errors occur during PKey#sign or PKey#verify.

Generic exception that is raised if an operation on a DH PKey fails unexpectedly or in case an instantiation of an instance of DH fails due to non-conformant input data.

Generic exception that is raised if an operation on a DSA PKey fails unexpectedly or in case an instantiation of an instance of DSA fails due to non-conformant input data.

Generic exception that is raised if an operation on an RSA PKey fails unexpectedly or in case an instantiation of an instance of RSA fails due to non-conformant input data.

Generic error class raised by SSLSocket and SSLContext.
