WebSHA-1: A 160-bit hash function which resembles the earlier MD5 algorithm. This was designed by the National Security Agency (NSA) to be part of the Digital Signature Algorithm. Cryptographic weaknesses were discovered in SHA-1, and the standard was no longer approved for most cryptographic uses after 2010.

WebTo get the Sha1 hash of a file, we simply supply a System.IO.FileInfo object as parameter: C# example System.IO.FileInfo data = new System.IO.FileInfo(@"c:\myfile.txt"); byte[] … In cryptography, SHA-1 (Secure Hash Algorithm 1) is a hash function which takes an input and produces a 160-bit (20-byte) hash value known as a message digest – typically rendered as 40 hexadecimal digits. It was designed by the United States National Security Agency, and is a U.S. Federal Information … See more SHA-1 produces a message digest based on principles similar to those used by Ronald L.
