Small program development function introduction: encryption and decryption NODE-UUID, Node-uuid can quickly generate UUID that complies with RFC4122 Specification version 1 or version 4. The js-base64 can realize Base64 encoding and decoding, and supports UTF-8 encoding. Crypto-js can be very convenient in JavaScript MD5, SHA1, SHA2, SHA3, RIPEMD-160 has

The globally unique identifier (guid,globally unique Identifier) is also known as the UUID (universally unique Identifier).A GUID is a numeric identifier generated by the algorithm with a binary length of 128 bits. The format of the GUID is "Xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", where X is a 32-bit hexadecimal number in the range of 0-9 or a-f. Ideally, no computer or computer cluster will generate two identical GUIDs.The total number of GUIDs reache

A globally unique identifier (guid,globally unique Identifier) is also known as a UUID (universally unique Identifier). A GUID is a 128-bit numeric identifier generated by the algorithm in binary length. The GUID is formatted as "Xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", where X is a 32-bit hexadecimal number in the range 0-9 or a-f. Ideally, no computer or cluster of computers will generate two identical GUIDs. The total number of GUIDs reached 2^128

In Android, several commonly used Bluetooth profiles are: spp (Serial Port profile), a2dp (Advanced Audio distribution profile), and avrcp (audio/video remote control profile), hid (Human Interface Device profile), HFP (hands-free profile ). Among them, media is highly correlated with a2dp and avrcp, which is often used for data communication.Concept of Bluetooth Profile Profile defines a Bluetooth-based application. Each profile specification mainly includes developer interfaces, message format

When operating TORTOISESVN, the following error is reported:Command UpdateRepository UUID ' 62b86956-73d9-2945-ba87-0546d71898f9 ' doesn ' t match expectedUUID ' 6aed1349-fe9f-9245-a4a0-02dba53eb2d0 'finished!As you can see, the UUID of the original repository creator is the former and the UUID of the latter is now being manipulated. Therefore, the current workar

Python uuid module instance, pythonuuid Uuid is a unique identifier used as an identifier in many fields. The uuid module of python is used to generate it.In other words, there are four uuid generation methods provided by python: 1. generate from hardware address and time2. generate from md5 Algorithm3. Random genera

A UUID is a number generated on a machine that guarantees that all machines in the same time and space are unique. Typically the platform provides the API to generate the UUID. The UUID is based on the standards established by the Open Software Foundation (OSF), using Ethernet card addresses, nanosecond-seconds, chip ID codes, and many possible numbers. A combina

A UUID is a number generated on a single machine that guarantees that all machines in the same space-time are unique. Typically, the platform provides APIs for generating UUID. The UUID, based on the standard calculations developed by the Open Software Foundation (OSF), uses Ethernet card addresses, nanosecond time, chip ID codes, and many possible numbers. A com

Introduction to UUID The UUID is a 128-bit globally unique identifier, typically represented by a 32-byte string. It guarantees the uniqueness of time and space, also known as GUIDs, which are all called: uuid--universally unique Identifier,python called UUID. It guarantees the uniqueness of the generation ID by MAC

List Builder/list resolution lists comprehension Simple and flexible to create lists, usually with lambda (), map (), filter () Create a list directly from a list of generated expressions. However, if you receive content restrictions, the list size is certainly limited. And, creating a list of 1 million elements, not only takes up a lot of storage space, but if we just need to access a few elements, then the other is white space. The list genera
