Bookmark or Share- What is SHA1 Hash? An In-depth Guide with ExamplesSHA-1 (Secure Hash Algorithm 1) is a cryptographic hash function that takes an input and produces a 160-bit (20-byte) hash value. It’s commonly used in various security applications and protocols. However, SHA-1 is no longer considered secure against well-funded attackers.
- What Is SHA-1? (SHA-1 & SHA-2 Definition) - LifewireSHA-1 (short for Secure Hash Algorithm 1) is one of several cryptographic hash functions . It's most often used to verify a file has been unaltered. This is done by producing a checksum before the file has been transmitted, and then again once it reaches its destination.
- SHA-1 - WikipediaSHA-1 produces a message digest based on principles similar to those used by Ronald L. Rivest of MIT in the design of the MD2, MD4 and MD5 message digest algorithms, but generates a larger hash value (160 bits vs. 128 bits). SHA-1 was developed as part of the U.S. Government's Capstone project.
- Secure Hash Algorithms - WikipediaSHA-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.
- SHA-1 Hash - GeeksforGeeksLast Updated : 09 Nov, 2023. SHA-1 or Secure Hash Algorithm 1 is a cryptographic algorithm which takes an input and produces a 160-bit (20-byte) hash value. This hash value is known as a message digest. This message digest is usually then rendered as a hexadecimal number which is 40 digits long.
