SHA 256 Algorithm

$begingroup$


I'm really confused about the computation about SHA 256.



enter image description here



The $W_t$ variable: What's the value of $W_t$? How do I get that value?



I'm still confused because the explanation using english languange. I'm a beginner guys, any help from you will be a plus point for me about hashing.

          It is in SHA-256 message schedule (NIST-FIPS 180-4);



          The message is first padded, then parsed into 512-bit as $M^{1},ldots,M^{N}$.



          The $M_t^{(i)}$ is the $t$-th 32 bit in the $i$-th value there for $0 leq t leq 15$



          The $W_t$ is defined as your equation.

          It is in SHA-256 message schedule (NIST-FIPS 180-4);



          The message is first padded, then parsed into 512-bit as $M^{1},ldots,M^{N}$.



          The $M_t^{(i)}$ is the $t$-th 32 bit in the $i$-th value there for $0 leq t leq 15$



          The $W_t$ is defined as your equation.
