Frequently asked questions
What is SHA-256?
SHA-256 is a cryptographic hash function that turns any input into a fixed 64-character hex digest. It is widely used for integrity checks and digital signatures.
Is MD5 still safe to use?
Not for security — MD5 is broken for collision resistance. It is still fine for checksums and non-security lookups.
Can a hash be reversed to get the original text?
No. Hashing is one-way. Given a digest you cannot recover the input, except by brute force for weak inputs.
What is the difference between SHA-1 and SHA-256?
SHA-1 produces 160-bit digests and is deprecated; SHA-256 produces 256-bit digests and remains secure.
