Specific contentIn Springcloudconfig, considering the security issues that all profiles are exposed to in the remote repository, there is a handling mechanism for secure access that encrypts some data and enables decryption control when read.2.1, key encryption processingThe so-called key processing refers to setting a public operation access password, and then through the Curl command to access t

There are two articles worth looking at:https://blog.csdn.net/wgw335363240/article/details/8878584
Conclusion:
1 AES encryption time and the size of the encrypted file is growing linearly, encrypting 1G of the file will take about 4 minutes, encryption speed is still very fast
2 The encrypted file size is twice times the size of the original file
3 The time required to decrypt the file is twice times the
It is estimated that there will be more updates in cryptography over time.
Asymmetric Encryption:Asymmetric encryption is the opposite of symmetric encryption concept, symmetric encryption refers to the encryption and decryption using the same key keys, such as Stream encryption

After several years of entering the programmer industry, there have been gains (enhanced technology) and efforts (time and sub-health status) in the past few years ). Of course, there is no regret, and the code is still long !!!
On The Way, never stop !!!
In the development process, I have also accumulated some exp
The difference between 16-bit MD5 encryption and 32-bit MD5 encryptionMD5 encryption is usually a 32-bit encoding, and in many places will use 16-bit encodingWhat difference do they have?16-bit encryption is to extract the middle 16 bits from the 32-bit MD5 hash!Actually cracked 16-bit MD5 hash is slower than cracking 32-bit MD5 hashBecause he has one more step,
Several common encryption functions in PHP and common encryption functions in PHP
MD5 encryption:
String md5 (string $ str [, bool $ raw_output = false])
1. by default, md5 () returns a hash value in the hexadecimal format of 32 characters. It accepts two parameters: the first is the string to be encrypted, and the second is the Boolean value of raw_output, the d

Advanced Encryption Standard (English: Advanced encryption Standard, abbreviation: AES), also known as the Rijndael encryption method in cryptography, is a block encryption standard used by the U.S. federal government. This standard, which replaces the original DES, has been analyzed and widely used worldwide. After fi

How to better encrypt a string? MD5, RSA, DES?Well, none of this is understood.Reference to the degree Niang, so the idea is:For encryption:· Remove a character from the string to be encrypted· The low-byte and Key1 of the characters are taken to make an XOR operation· Take the high byte of the character· Synthesize the data after the operation to a new characterFor decryption:· Remove a character from the string to decrypt· The low-byte and Key1 of t
