After the authority confirmed that the SHA1 encryption algorithm is more and more high, SHA fingerprint fraud cost is getting lower, then Microsoft, Google and other IT giants have released the SHA1 encryption algorithm declaration, the third-party
This paper mainly describes the process of computing the Information digest using the SHA1 algorithm.Security System (0)--encryption and decryption algorithm, message digest, message authentication technology, digital signature and public key
1.MD5 algorithmNon-reversible128-bit or 64-bit string, byte digit length is 16 and 8, the general expression is to use the 16 binary to represent, 1 byte is converted to 2 16bit, representing the high status, so the generated string is 16 bit or 32
After the authority confirmed that the SHA1 encryption algorithm is more and more high, SHA fingerprint fraud cost is getting lower, then Microsoft, Google and other IT giants have released the SHA1 encryption algorithm declaration, the third-party
When we upload and download files, it can easily lead to the lack of files, so how to solve this problem? Users usually check using the SHA1 value. Today small compilation teaches everybody how to examine the file the SHA1 value.
