Summary

The Java platform defines a set of programming interfaces for performing cryptographic operations. The cryptographic interfaces are provider-based. This architecture supports different provider implementations. Some providers may perform cryptographic operations in software; others may perform the operations on a hardware token for example, on a smartcard device or on a hardware cryptographic accelerator.

No modifications to the application are required. The only requirement is to properly configure the provider. Although an application can make use of most PKCS 11 features using existing APIs, some applications might need more flexibility and capabilities. For example, an application might want to deal with smartcards being removed and inserted dynamically more easily. Or, a PKCS 11 token might require authentication for some non-key-related operations and therefore, the application must be able to log into the token without using keystore.

The JCA gives applications greater flexibility in dealing with different providers.

Announcing new high-level PKCS#11 HSM support for Python

This document describes how native PKCS 11 tokens can be configured into the Java platform for use by Java applications. The SunPKCS11 provider, in contrast to most other providers, does not implement cryptographic algorithms itself. This implementation must take the form of a shared-object library. Consult your vendor documentation to find out if your cryptographic device includes such a PKCS 11 implementation, how to configure it, and what the name of the library file is.

To use the provider, you must first install it statically or programmatically. For example, here's a fragment of the java. To install the provider dynamically, create an instance of the provider with the appropriate configuration filename and then install it. Here is an example. Save the returned Provider object from the configure method, then add that object, as demonstrated in this example:. Don't add the provider from which you called the configure method:.

If this provider cannot be configured in-place, then a new provider is created and returned. Therefore, always use the provider returned from the configure method. To use more than one slot per PKCS 11 implementation, or to use more than one PKCS 11 implementation, simply repeat the installation for each with the appropriate configuration file. The valid values for attribute and value are described in the table in this section:.

Comments are denoted by lines starting with the number symbol. At most, you can specify one of enabledMechanisms or disabledMechanisms. Specifies the the full pathname including extension of the PKCS 11 implementation; the format of the pathname is platform dependent.While it was developed by RSA, as part of a suite of standards, the standard is not exclusive to RSA ciphers and is meant to cover a wide range of cryptographic possibilities.

A slot originally referred to a single card slot on a smartcard device that could accept a token. A token was a smartcard that contained secure, encrypted keys and certificates.

You would insert your smartcard token into the slot, and use its contents to do cryptographic operations. Nowadays the distinction is more blurry. Server devices often make use of software tokens softcardswhich appear as slots within PKCS 11, but no physical device exists. These devices can also feature physical slots and accelerator slots. Slots have pkcs Tokens are secured with a passphrase PIN. Not all implementations use pins in their underlying implementation, but these are required for PKCS Some implementations let you control the behaviour of their PKCS 11 module in ways not specified by the specification through environment variables e.

The PKCS 11 library is running within your process, using your memory, etc. It may talk to a daemon to access the underlying hardware, or it may be talking directly. Environment variables set on your process can be used to configure the behaviour of the library, check the documentation for your device. Different devices support different cryptographic operations. In PKCS 11 mechanisms refer to the combination of cipher e. AEShash function e.

SHA and block mode e. Mechanisms also exist for generating keys, and deriving keys and parameters. The capabilities of a mechanism indicate what types of operations can be carried out with the mechanism, e.

Not all devices support all mechanisms. Some may support non-standard mechanisms. Not all devices support the same capabilities for mechanisms or same key lengths. This information can be retrieved via pkcs Some mechanisms require mechanism parameters. These are used to provide additional context to the mechanism that does not form part of the key. The pkcs Mechanism type includes information on the required parameters for common mechanisms.

A complete list of current mechanisms and historical mechanisms includes the mechanism parameters and input requirements for each mechanism.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

This is a low-level interface to create any type of object and can be used for importing data onto the Token. The local parameter creates a Python object that is not created on the HSM its object handle will be unset. This is useful if you only need the domain parameters to create another object, and do not need a real PKCS 11 object in the session. Domain parameters have no id or labels.

What Can You Do with Python? - The 3 Main Applications

Search PyPI Search. Latest version Released: Feb 28, To create a new project, you just need to POST the name you want to give to the new project to the project base URL.

You can also use curl to customize your new project with a category, description, or tags. Once a project has been successfully created it will have the following properties.

To update a project, you need to PUT an object containing the fields that you want to update to the project' s base URL. Successful DELETEs will return "204 no content" responses with no body. Once you delete a project, it is permanently deleted.

If you try to delete a project a second time, or a project that does not exist, you will receive a "404 not found" response. However, if you try to delete a project that is being used at the moment, then BigML. To list all the projects, you can use the project base URL. By default, only the 20 most recent projects will be returned. You can get your list of projects directly in your browser using your own username and API key with the following links.

You can also paginate, filter, and order your projects. Sources Last Updated: Monday, 2017-10-30 10:31 A source is the raw data that you want to use to create a predictive model. A source is usually a (big) file in a comma separated values (CSV) format. See the example below. Each row represents an instance (or example).

Each column in the file represents a feature or field. The last column usually represents the class or objective field. The file might have a first row named header with a name for each field. See below for more details. You can also list all of your sources. The first dictionary defines the keys that will be selected. To create a new source, you need to POST the file containing your data to the source base URL.

The file must be attached in the post as a file upload. This allows you to upload binary files in compressed format (. You can easily do this using curl. The option -H lets curl set the content type header while the option -X sets the http method.

You will get the access token and the refresh token. Google Drive example:Select the option to create source from Google Drive: Allow BigML access to your Google Drive: Get the access token and refresh token: After complete these steps you need to POST to the source endpoint URL an object containing at least the file ID (for Google Drive) or the bucket and the file name (for Google Storage) and the access token.

Including also the refresh token is optional before your access token expires. Including it avoids you to be worried about expiration time. You first need to authorize BigML access from your own Google Apps application. After the authorization process you will get your access token and refresh token from the Google Authorization Server.Achieved 1st Target 208. Total Profit made 1. Low Risk Taker Book Profit of 0.

For example, you might be interested in the exam marks of all students in the UK. It is not feasible to measure all exam marks of all students in the whole of the UK so you have to measure a smaller sample of students (e.

Properties of samples, such as the mean or standard deviation, are not called parameters, but statistics. Inferential statistics are techniques that allow us to use these samples to make generalizations about the populations from which the samples were drawn. It is, therefore, important that the sample accurately represents the population. The process of achieving this is called sampling (sampling strategies are discussed in detail here on our sister site).

Inferential statistics arise out of the fact that sampling naturally incurs sampling error and thus a sample is not expected to perfectly represent the population. The methods of inferential statistics are (1) the estimation of parameter(s) and (2) testing of statistical hypotheses.

We have provided some answers to common FAQs on the next page.

Alternatively, why not now read our guide on Types of Variable. Descriptive Statistics Descriptive statistics is the term given to the analysis of data that helps describe, show or summarize data in a meaningful way such that, for example, patterns might emerge from the data. Typically, there are two general types of statistic that are used to describe data: Measures of central tendency: these are ways of describing the central position of a frequency distribution for a group of data.

In this case, the frequency distribution is simply the distribution and pattern of marks scored by the 100 students from the lowest to the highest. We can describe this central position using a number of statistics, including the mode, median, and mean. You can read about measures of central tendency here. Measures of spread: these are ways of summarizing a group of data by describing how spread out the scores are. For example, the mean score of our 100 students may be 65 out of 100.

However, not all students will have scored 65 marks. Rather, their scores will be spread out. Some will be lower and others higher. Measures of spread help us to summarize how spread out these scores are. To describe this spread, a number of statistics are available to us, including the range, quartiles, absolute deviation, variance and standard deviation.

When we use descriptive statistics it is useful to summarize our group of data using a combination of tabulated description (i.
