Frequently Asked Questions
What is a cryptographic hash?
A hash function takes any input and produces a fixed-length string (the hash or digest). The same input always produces the same output, but it's computationally infeasible to reverse — making it ideal for checksums and data verification.
Which hash algorithm should I use?
For security-sensitive uses, SHA-256 or SHA-512 are recommended. MD5 and SHA-1 are considered cryptographically broken for security purposes but are still useful for checksums and data integrity checks.
Can hashes be reversed?
No. Hash functions are one-way by design. You cannot reconstruct the original input from a hash. However, common passwords can be cracked via rainbow tables — always salt your hashes in authentication systems.
What's the difference between MD5 and SHA-256?
MD5 produces a 128-bit (32-character hex) hash and is fast but no longer secure. SHA-256 produces a 256-bit (64-character hex) hash and is considered cryptographically safe for most applications.
