Results for: "pstore"

Generic exception class of the Timestamp module.

Allows to create timestamp requests or parse existing ones. A Request is also needed for creating timestamps from scratch with Factory. When created from scratch, some default values are set:

• version is set to 1

• cert_requested is set to true

• algorithm, message_imprint, policy_id, and nonce are set to false

Used to generate a Response from scratch.

Please bear in mind that the implementation will always apply and prefer the policy object identifier given in the request over the default policy id specified in the Factory. As a consequence, default_policy_id will only be applied if no Request#policy_id was given. But this also means that one needs to check the policy identifier in the request manually before creating the Response, e.g. to check whether it complies to a specific set of acceptable policies.

There exists also the possibility to add certificates (instances of OpenSSL::X509::Certificate) besides the timestamping certificate that will be included in the resulting timestamp token if Request#cert_requested? is true. Ideally, one would also include any intermediate certificates (the root certificate can be left out - in order to trust it any verifying party will have to be in its possession anyway). This simplifies validation of the timestamp since these intermediate certificates are “already there” and need not be passed as external parameters to Response#verify anymore, thus minimizing external resources needed for verification.

Example: Inclusion of (untrusted) intermediate certificates

Assume we received a timestamp request that has set Request#policy_id to nil and Request#cert_requested? to true. The raw request bytes are stored in a variable called req_raw. We’d still like to integrate the necessary intermediate certificates (in inter1.cer and inter2.cer) to simplify validation of the resulting Response. ts.p12 is a PKCS#12-compatible file including the private key and the timestamping certificate.

req = OpenSSL::Timestamp::Request.new(raw_bytes)
p12 = OpenSSL::PKCS12.new(File.binread('ts.p12'), 'pwd')
inter1 = OpenSSL::X509::Certificate.new(File.binread('inter1.cer'))
inter2 = OpenSSL::X509::Certificate.new(File.binread('inter2.cer'))
fac = OpenSSL::Timestamp::Factory.new
fac.gen_time = Time.now
fac.serial_number = 1
fac.allowed_digests = ["sha256", "sha384", "sha512"]
#needed because the Request contained no policy identifier
fac.default_policy_id = '1.2.3.4.5'
fac.additional_certificates = [ inter1, inter2 ]
timestamp = fac.create_timestamp(p12.key, p12.certificate, req)

Attributes

default_policy_id

Request#policy_id will always be preferred over this if present in the Request, only if Request#policy_id is nil default_policy will be used. If none of both is present, a TimestampError will be raised when trying to create a Response.

call-seq:

factory.default_policy_id = "string" -> string
factory.default_policy_id            -> string or nil

serial_number

Sets or retrieves the serial number to be used for timestamp creation. Must be present for timestamp creation.

call-seq:

factory.serial_number = number -> number
factory.serial_number          -> number or nil

gen_time

Sets or retrieves the Time value to be used in the Response. Must be present for timestamp creation.

call-seq:

factory.gen_time = Time -> Time
factory.gen_time        -> Time or nil

additional_certs

Sets or retrieves additional certificates apart from the timestamp certificate (e.g. intermediate certificates) to be added to the Response. Must be an Array of OpenSSL::X509::Certificate.

call-seq:

factory.additional_certs = [cert1, cert2] -> [ cert1, cert2 ]
factory.additional_certs                  -> array or nil

allowed_digests

Sets or retrieves the digest algorithms that the factory is allowed create timestamps for. Known vulnerable or weak algorithms should not be allowed where possible. Must be an Array of String or OpenSSL::Digest subclass instances.

call-seq:

factory.allowed_digests = ["sha1", OpenSSL::Digest.new('SHA256').new] -> [ "sha1", OpenSSL::Digest) ]
factory.allowed_digests                                               -> array or nil

This handler will capture an event and record the event. Recorder events are available vial Psych::Handlers::Recorder#events.

For example:

recorder = Psych::Handlers::Recorder.new
parser = Psych::Parser.new recorder
parser.parse '--- foo'

recorder.events # => [list of events]

# Replay the events

emitter = Psych::Emitter.new $stdout
recorder.events.each do |m, args|
  emitter.send m, *args
end

Represents a YAML stream. This is the root node for any YAML parse tree. This node must have one or more child nodes. The only valid child node for a Psych::Nodes::Stream node is Psych::Nodes::Document.

This class walks a YAML AST, converting each node to Ruby

Switch that takes an argument.

A FetchError that indicates that the reason for not being able to fetch data was that the host could not be contacted

Specifies a Specification object that should be activated. Also contains a dependency that was used to introduce this activation.

Used Internally. Wraps a Dependency object to also track which spec contained the Dependency.

An absolutely silent download reporter.

This is the JSON generator implemented as a C extension. It can be configured to be used by setting

JSON.generator = JSON::Ext::Generator

with the method generator= in JSON.

Includes URI::REGEXP::PATTERN

IO wrapper that provides only write

Indicates a problem with the DNS request.
