Password encryption algorithm in SpringSecurity: use and principle of BCryptPasswordEncoder

There is an encryption class BCryptPasswordEncoder in Spring Security. Its use is very simple and interesting. Let’s see its use. Usage of BCryptPasswordEncoder First create a SpringBoot project and add Spring Security dependencies when creating the project. Then we add a test class and write the following code: final private String password = “123456”; @Test […]

Why is it said that Decoder and Encoder are the core components of Netty? How does Netty use the template method pattern to efficiently complete decoding and encoding? A thorough analysis in 10,000 words

The job of the Netty inbound processor is the packet decoding and business processing of the IO processing operation. During the inbound processing, the bottom layer of Netty first reads the ByteBuf binary data, and finally needs to convert it into a java POJO object. This process requires a Decoder to complete. The job of […]

DIP encoder and decoder neural network structure code with skip connections

“”” This code implements an encoder and decoder neural network structure with skip connections 1: Define a function skip that accepts a series of parameters to build the network 2: Ensure that the lengths of parameters num_channels_down, num_channels_up, and num_channels_skip are the same through assert, otherwise an exception will be thrown. Note: These three parameters […]

MysteryTwister AES Key – encoded in the machine readable zone of a European ePassportSolution

Question Overview Question link: Level II Challenges | MysteryTwister – The Cipher Contest Full translation, Ref: https://www.codenong.com/cs109540921/ 1. The AES encryption mode is CBC, the initialization vector (IV) is zero, and the padding is 01-00. Furthermore, the corresponding key is in a form such as the Machine Readable Zone (MRZ) on the ID document, which […]

News text classification-BERT pre-training model and Transformer Encoder solution

Preliminary presets solve the problem using transformers’ form_pretrained, but by looking at the dataset: label text 2 2967 6758 339 2021 1854 3731 4109 3792 … It can be seen that the training set is divided by \t, which does not meet the format requirements of loaddata(). And analyzing the data characteristics, it can be […]
