Frequently Asked Questions
How can you identify a hash without knowing the plaintext?
Hashes have distinct mathematical characteristics including output bit lengths (e.g. 128-bit MD5 is always 32 hex chars, 256-bit SHA-256 is 64 hex chars) and unique modular crypt format prefixes ($2a$, $argon2id$, $6$).
Why are MD5 and SHA-1 considered broken?
MD5 and SHA-1 have proven practical collision vulnerabilities where two different inputs produce identical hash outputs, making them unsafe for cryptographic signatures.
