The truncated versions of these values include SHA-224, SHA-384 and SHA-512 and SHA-224 or SHA-256. The former consists of the word value range of 32 words, whereas the latter consists of the 64-bit word value. This forms a family of 2 identical hash functions, which consist of differently sized block sizes which are known to be SHA-512 and SHA-256, which differ mainly in the word size. The weaknesses related to the cryptographic techniques were found in SHA-1 the encryption standard was later on discarded and was not much put to use. the National Security Agency and was supposed to be part of the critical component- Digital Signature Algorithm (DSA). The particular algorithm was designed and developed by the NSA, i.e. It is a 160 bit or a 20-byte long hash-based function-based encryption mechanism that is used to resemble the year-old MD5 algorithm. It was withdrawn very shortly after it was published due to a major flaw, and therefore SHA-1 came into the picture. It is a retronym that is applied to the basic version of the year-old 160 bit or 20-byte long hash function, which was published back in 1993 with the name of the SHA algorithm. The Different Types of SHA algorithm include the ones:

The collision resistance implies that finding two different sets of inputs that hash to the same hash is extremely difficult and therefore marks its safety.

Therefore, the ratio to the number of inputs and the outputs should be similar in fashion to comply with the pigeonhole principle.

The last and most difficult to crack is the collision resistance, making it extremely hard for the attacker to find two completely different messages which hash to the same hash value.

Similarly, the second resistance technique is applied where the attacker has to go through a hard time decoding the next error message even when the first level of the message has been decrypted.

The pre-image resistance is important to clear off brute force attacks from a set of huge and powerful machines.

The security, therefore, is provided by the nature of a one way that has a function that is mostly the key component of the SHA algorithm.

The cornerstone lies in the fact that the pre-image crypt resistance technique makes it hard and more time consuming for the hacker or the attacker to find the original intended message by providing the respective hash value.

The cryptographic hash functions are utilized and used to keep and store the secured form of data by providing three different kinds of characteristics such as pre-image resistance, which is also known as the first level of image resistance, the second level of pre-image resistance and collision resistance.
