what is sha1 hash

SHA-1 – Wikipedia

In cryptography, SHA-1 ( Secure Hash Algorithm 1) is a cryptographic hash function which takes an input and produces a 160- bit (20- byte) hash value known as a message digest – typically rendered as a hexadecimal number, 40 digits long. It was designed by the United States National Security Agency, and is …

What Is SHA-1? (SHA-1 & SHA-2 Definition) – Lifewire

SHA-1 is the second iteration of this cryptographic hash function. SHA-1 also has a message digest of 160 bits and sought to increase security by fixing a weakness found in SHA-0. However, in 2005, SHA-1 was also found to be insecure.

The Difference Between SHA-1, SHA-2 and SHA-256 Hash

SHA-1, SHA-2, SHA-256, SHA-384 – What Does It All Mean!!

SHA1 vs SHA256 – KeyCDN Support

SHA, which stands for secure hash algorithm, is a cryptographic hashing algorithm used to determine the integrity of a particular piece of data. Variations of this algorithm are often used by SSL certificate authorities to sign certificates. This algorithm help ensures …

The SHA1 hash function is now completely unsafe

A hash function such as SHA-1 is used to calculate an alphanumeric string that serves as the cryptographic representation of a file or a piece of data. This is called a digest and can serve as a digital signature. It is supposed to be unique and non-reversible.

SHA1 Hash Generator

SHA-1 (Secure Hash Algorithm) is a 160 bit cryptographic hash function created by the NSA in 1995. It creates a 40 byte hash value for the input of the algorithm. SHA-1 is one-way, meaning that the original input cannot be be determined simply by knowing the hash value.

What is the Secure Hash Algorithm 1 (SHA-1)? – Definition

The Secure Hash Algorithm 1 (SHA-1) is a cryptographic computer security algorithm. It was created by the US National Security Agency in 1995, after the SHA-0 algorithm in 1993, and it is part of the Digital Signature Algorithm or the Digital Signature Standard (DSS).

What Are MD5, SHA-1, and SHA-256 Hashes, and How Do I

Hashes are the products of cryptographic algorithms designed to produce a string of characters. Often these strings have a fixed length, regardless of the size of the input data. Take a look at the above chart and you’ll see that both “Fox” and “The red fox jumps over the blue dog” yield the same length output.

SHA-2 – Wikipedia

SHA-2 ( Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA). They are built using the Merkle–Damgård structure, from a one-way compression function itself built using the Davies–Meyer structure from a …
