❓ Frequently Asked Questions
Q. Which hashing algorithms are computed locally?
MD5, SHA-1, SHA-256, SHA-384, and SHA-512 are calculated purely on your machine using the browser's native Web Cryptography API.
Q. Can a cryptographic hash be decrypted back to plaintext?
No. Cryptographic hash functions are strictly one-way mathematical operations. The original input cannot be reverse-engineered from the digest.
Q. Is hashing safe for verifying file or payload integrity?
Yes, SHA-256 digests provide collision-resistant digital fingerprints ideal for checksum validation and verifying software downloads.
