Frequently Asked Questions
Why is SHA256 the industry standard?
SHA256 offers a balance of performance and extreme security. With 256 bits, the probability of a collision (two different texts producing the same hash) is astronomically low, making it safe for digital signatures and cryptocurrencies.
Can SHA256 be reversed?
No. Like all cryptographic hashes, it is a one-way function. It is designed so that you cannot reconstruct the original data from the hash, preserving data privacy.
What is the difference between SHA256 and SHA-2?
SHA-2 is the 'family' of algorithms (which includes SHA-224, SHA-256, SHA-384, SHA-512). SHA256 is the most popular and widely used specific implementation within that family.
