bold fashion jewelry wholesale The hash algorithm maps the binary value of any length to a smaller binary value of the fixed length. This small binary value is called the hash value. The hash value is the only and extremely compact value of the data. If a paragraph of the extension and even if only one letter from the paragraph, the subsequent hash will generate different values. It is basically impossible to find two different inputs with the same value as the same value.
In information authentication code (MAC) hash function is usually used to sign the data with digital signatures, while message detection code (MDC) hash function is used for data integrity.
The basic information of the entire Bitcoin network is as follows:
The digital currency that requires mining has hash value, such as Litecoin, Ruitai, dog currency, micro -alliance Coins, some coins, ingots, etc.
jewelry making wholesale suppliers The hash algorithm is a cryptographic algorithm that can only be encrypted and cannot be decrypted. The information of any length can be converted into a fixed -length string.
This string has two features:
1. Even if the input value is only changed, the output hash value will be different.
2, only the same input value can get the exactly the same output value.
3, there is no regular input value and output value, so the input value cannot be calculated by the output value. If you want to find the specified output value, you can only adopt an enumeration method: constantly replace the input value to find the output value that meets the conditions.
Have algorithm guarantees that Bitcoin mining cannot derive the results in reverse. Therefore, the continuous operation of the miners is essentially the correct input value of violent cracking. Whoever finds first can get Bitcoin rewards.
