Secure Hash Algorithms Secure Hash Algorithms, also known as SHA, are a family of cryptographic functions designed to keep data secured. It works by transforming the data using a hash function: an algorithm that consists of bitwise operations, modular additions, and compression functions A secure hash algorithm is actually a set of algorithms developed by the National Institutes of Standards and Technology (NIST) and other government and private parties. These secure encryption or file check functions have arisen to meet some of the top cybersecurity challenges of the 21st century, as a number of public service groups work with.

A secure hash algorithm, often known simply as an SHA, is a hashing algorithm that is considered cryptographically secure. In general, hashing functions are used to sort and organize digital data into smaller, more categorized packets SHA-1 or Secure Hash Algorithm 1 is a cryptographic hash function 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 Secure Hash Algorithms (SHA) SHA is a family of four hashing algorithms: SHA-0, SHA-1, SHA-2, and SHA-3. Although SHA-3 offers the highest level of security, SHA-2 is more widely used today. Beginning in January 2016, all Certificate Authorities (CAs) only issue SHA-2 SSL certificates
