Description

• This tool generates the SHA224 hash of a given text.

Facts

• SHA-224 is a very commonly used hash function and a member of the SHA2 or SHA-2 algorithm family, which stands for Secure Hash Algorithm 2.
• SHA-224 is a cryptographic hash function which takes an input text and generates a 224-bit hash value which is 56 characters in length.
• The SHA-224 hash value of an empty string or empty file is d14a028c2a3a2bc9476102bb288234c415a2b01f828ea62ac5b3e42f.
• SHA-224 uses a Merkle-Damgard construction, which means that it processes the input message in blocks and iteratively produces an output for each block.
• SHA-224 is not a widely used hash function compared to its variants such as SHA-256, SHA-384, and SHA-512.
• SHA-224 has been implemented in various programming languages such as C, Java, Python, and Ruby.
• The computational cost of SHA-224 depends on the size of the input message, but it is generally very fast and can process large amounts of data quickly.
• There have been some attacks on SHA-224, but they are considered to be impractical and not a significant threat to its security.
• Some other cryptographic hash functions that are similar to SHA-224 include RIPEMD-160 and SHA-3/Keccak-224.
• The development of SHA-224 and other SHA algorithms was partly motivated by the need for stronger cryptographic functions after the weaknesses of MD5 and SHA-1 were discovered.
• SHA-224 was developed by the National Security Agency (NSA) and published by the National Institute of Standards and Technology (NIST) in 2001.
