Frequently Asked Questions
Which SHA algorithm should I use?
SHA-256 is the modern industry standard for general security and cryptographic verification. SHA-512 provides maximum bit-depth and collision resistance.
What is the difference between SHA-1, SHA-2, and SHA-3?
SHA-1 is deprecated due to collision weaknesses. SHA-2 (SHA-256/SHA-512) is the current global standard. SHA-3 is the newest NIST standard based on the Keccak sponge construction.
Is SHA-256 resistant to quantum computing attacks?
Yes. Grover's quantum search algorithm only halves the effective bit security of hash functions, leaving SHA-256 with 128 bits of security—still mathematically unbreakable.
