This article mainly introduces "how to call Crypto password library". In the daily operation, I believe many people have doubts about how to call the password library of Crypto. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts of "how to call Crypto password library". Next, please follow the editor to study!

Sha256 encryption algorithm

Sha series encryption algorithms include many, basically have the following formats of encryption, the larger the number of bits, the greater the encryption strength, this algorithm is an one-way encryption algorithm similar to MD5, but more secure than MD5.

SHA-1: the performance of generating feeds is slightly lower than that of MD5

SHA-256: can generate a summary of information about the length 256bit

SHA-224: can generate a summary of information about the length 224bit

SHA-384: can generate a summary of information about the length 384bit

SHA-512: can generate a summary of information about the length 512bit
