- How long would it take for a sha256 digest loop to reach the . . .
If values generated by sha256 can be assumed to be distributed uniformly and randomly, then there exists with probability 1−1 e (about 63%) a 256-bit sequence whose sha256 hash is equal to itself If so, the minimum sequence length is one
- sha 256 - Do any other factors aside from length of input . . .
The answer, with plausible implementations, is no SHA-256 (like all common hash algorithms: MD5, SHA-1, SHA2, SHA3, Blake, etc ) only uses the message for bitwise operations (and, or, xor, shifts by a constant size, negation) and additions
- How long does it take to perform a single SHA256?
So your answer is that a sha256 hash takes 3 8*10^-8 s on the best-suited non-specialized CPU What you want to do with this value is rather unclear, though You might have to account for pipelining, instruction fetching, or even a memory access, as with all instructions
- Part 5: Hashing with SHA-256. An overview of SHA-256, a . . .
In SHA-256, messages up to 2⁶⁴ bit (2 3 exabytes, or 2 3 billion gigabytes) are transformed into digests of size 256 bits (32 bytes)
