Also question is, how does sha256 algorithm work?
This Protocol works with information broken down into pieces of 512 bits (or 64 bytes in other words). It produces its cryptographic “mixing” and then issues a 256-bit hash code. The algorithm includes a relatively simple round, which is repeated 64 times. characteristics of the message digest size (bytes): 32.
Secondly, what does sha256 stand for? Secure Hash Algorithm 256-bit
Similarly one may ask, what is a digest algorithm?
A message digest algorithm or a hash function, is a procedure that maps input data of an arbitrary length to an output of fixed length. Output is often known as hash values, hash codes, hash sums, checksums, message digest, digital fingerprint or simply hashes.
Is Sha 256 reversible?
SHA–256 is NOT reversible. Hash functions are used as one-way methods. They take the data (messages) and compute hash values (digests). Using SHA–256 on text data of 750,000 characters, we obtain a mere 64 digits digest.
