Frequently Asked Questions (FAQ)

Q Which hash algorithm is recommended for security?
SHA-256 and SHA-512 are currently recommended for cryptographic integrity and verification. MD5 and SHA-1 should only be used for non-security checksums and legacy compatibility.
Q Can hash functions be reversed to discover the original text?
Cryptographic hash functions are one-way mathematical algorithms designed to be computationally irreversible.
Q Is there a limit on input length?
You can hash short passwords, lengthy paragraphs, JSON payloads, or multi-line configuration blocks smoothly.
