BR/EDR Legacy Pairing utilizes the E21 or E22 algorithms based on SAFER+. Device authentication is based on the E1 algorithm, which is also based on SAFER+. Encryption utilizes the E0 algorithm derived from the MasseyRueppel algorithm. There is no provision for cryptographic message integrity. While the CRC provides some integrity protection, it is not considered to provide cryptographic integrity as it can be easily forged.

BR/EDR Legacy Pairing使用基于SAFER+的E21或E22算法。设备认证基于E1算法,也是基于SAFER+的。加密使用从MasseyRueppel算法中派生的E0算法。没有提供加密消息完整性的规定。虽然CRC提供了一定的完整性保护,但它不被认为能提供加密完整性,因为它很容易被伪造。

The largest animal ever to have lived on Earth is the dinosaur Argentinesaurus, a hulking的英文全文
The largest animal ever to have lived on Earth is the dinosaur Argentinosaurus, a hulking beast that roamed the planet over 90 million years ago. This massive herbivore was estimated to have weighed around 100 tons and reached a length of up to 100 feet, making it larger than any known land animal today.
Argentinosaurus belonged to a group of dinosaurs called titanosaurs, which were characterized by their long necks and tails, as well as their massive size. These giants were able to grow to such an enormous size due to a number of factors, including their herbivorous diet, which allowed them to consume large quantities of plant material, and their unique skeletal structure, which allowed them to support their massive bodies.
Despite their impressive size, however, titanosaurs were not invincible. Like all dinosaurs, they eventually went extinct, likely due to a combination of factors such as climate change and competition from other animals.
Today, the legacy of Argentinosaurus and other titanosaurs lives on in the form of the fossils they left behind. These incredible remnants of a bygone era continue to captivate scientists and the public alike, offering a glimpse into the incredible diversity of life that once existed on our planet.
deprecation: sklearn is being installed using the legacy 'setup.py install
在安装sklearn时提示"Deprecation: sklearn is being installed using the legacy 'setup.py install",这是由于通过执行'python setup.py install'安装sklearn的方式已经不推荐使用,被认为是过时的方法。
早期,安装Python库时可以使用'python setup.py install'命令进行安装,但随着时间的推移,Python社区更加推崇使用包管理工具,例如pip,来安装Python库。
通过使用pip,我们可以更方便地管理Python库的安装、更新和卸载,而不需要手动下载源代码并执行安装命令。
对于sklearn库,我们应该使用以下pip命令进行安装:
pip install scikit-learn
这将从Python Package Index(PyPI)下载并安装最新版本的sklearn库。
因此,如果我们使用过时的方式'python setup.py install'安装sklearn,会收到"Deprecation"(弃用)的警告,提醒我们使用pip安装库的推荐方式。
总之,为了避免警告信息,请使用pip来安装sklearn库,命令为pip install scikit-learn。
