The parent class for all primitive encodings. Attributes are the same as for ASN1Data, with the addition of tagging. Primitive values can never be encoded with indefinite length form, thus it is not possible to set the indefinite_length attribute for Primitive and its sub-classes.

Primitive sub-classes and their mapping to Ruby classes

• OpenSSL::ASN1::EndOfContent <=> value is always nil

• OpenSSL::ASN1::Boolean <=> value is true or false

• OpenSSL::ASN1::Integer <=> value is an OpenSSL::BN

• OpenSSL::ASN1::BitString <=> value is a String

• OpenSSL::ASN1::OctetString <=> value is a String

• OpenSSL::ASN1::Null <=> value is always nil

• OpenSSL::ASN1::Object <=> value is a String

• OpenSSL::ASN1::Enumerated <=> value is an OpenSSL::BN

• OpenSSL::ASN1::UTF8String <=> value is a String

• OpenSSL::ASN1::NumericString <=> value is a String

• OpenSSL::ASN1::PrintableString <=> value is a String

• OpenSSL::ASN1::T61String <=> value is a String

• OpenSSL::ASN1::VideotexString <=> value is a String

• OpenSSL::ASN1::IA5String <=> value is a String

• OpenSSL::ASN1::UTCTime <=> value is a Time

• OpenSSL::ASN1::GeneralizedTime <=> value is a Time

• OpenSSL::ASN1::GraphicString <=> value is a String

• OpenSSL::ASN1::ISO64String <=> value is a String

• OpenSSL::ASN1::GeneralString <=> value is a String

• OpenSSL::ASN1::UniversalString <=> value is a String

• OpenSSL::ASN1::BMPString <=> value is a String

OpenSSL::ASN1::BitString

Additional attributes

unused_bits: if the underlying BIT STRING’s length is a multiple of 8 then unused_bits is 0. Otherwise unused_bits indicates the number of bits that are to be ignored in the final octet of the BitString’s value.

OpenSSL::ASN1::ObjectId

NOTE: While OpenSSL::ASN1::ObjectId.new will allocate a new ObjectId, it is not typically allocated this way, but rather that are received from parsed ASN1 encodings.

Additional attributes

• sn: the short name as defined in <openssl/objects.h>.

• ln: the long name as defined in <openssl/objects.h>.

• oid: the object identifier as a String, e.g. “1.2.3.4.5”

• short_name: alias for sn.

• long_name: alias for ln.

Examples

With the Exception of OpenSSL::ASN1::EndOfContent, each Primitive class constructor takes at least one parameter, the value.

Creating EndOfContent

eoc = OpenSSL::ASN1::EndOfContent.new

Creating any other Primitive

prim = <class>.new(value) # <class> being one of the sub-classes except EndOfContent
prim_zero_tagged_implicit = <class>.new(value, 0, :IMPLICIT)
prim_zero_tagged_explicit = <class>.new(value, 0, :EXPLICIT)

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

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

Immutable and read-only representation of a timestamp token info from a Response.

Default formatter for log messages.

Predefined Keys

CSV::InputsScanner receives IO inputs, encoding and the chunk_size. It also controls the life cycle of the object with its methods keep_start, keep_end, keep_back, keep_drop.

CSV::InputsScanner.scan() tries to match with pattern at the current position. If there’s a match, the scanner advances the “scan pointer” and returns the matched string. Otherwise, the scanner returns nil.

CSV::InputsScanner.rest() returns the “rest” of the string (i.e. everything after the scan pointer). If there is no more data (eos? = true), it returns “”.
