1 sha Encryption: Secure Hash algorithm is mainly applicable to digital signature algorithms (Digital Signature algorithm DSA) defined in the digital signature standard (Digital Signature Standard DSS). For messages that are less than 2^64 bits in

Preface This is a teaching article, mainly for understanding the Ethernet square and block chain technology used. It was a technical curiosity to write this article. Block-chain technology began to use virtual currency, in which Ben Cong started

Introduction to guidThe Open Software Foundation (OSF) has developed an algorithm that can generate unique identifiers to generate a globally unique identifier (UUID ). Microsoft uses the same algorithm in the Naming Standard of com! In COM,

First: The basics: Add salt hash (Hashing with salt) We already know how quickly malicious attackers use query tables and rainbow tables to crack common hash encryption. We have also It is understood that this problem can be solved by using a

OrderThe basic one-way encryption algorithm--MD5 is introduced in the previous article, and the principle of its realization is also roughly stated. This article continues the one-way encryption mentioned earlier, mainly on Sha, like MD5, Sha is

The Java encryption and decryption technology series SHA Order Background Body Comparison of SHA-1 and MD5 Code implementation Conclusion OrderThe basic one-way encryption algorithm--MD5 is introduced in the

password by adding salt, you can increase the complexity of the password, even if the simplest password, after adding salt, can also become a complex string, which greatly improve the difficulty of password cracking. However, if the salt is hard

Wallets are used on public chains such as Bitcoin/Ethereum. Wallets are primarily used to manage the user's private key, and the user's digital currency on the chain, which is the signature of the transaction with the private key. The private key
