SHA-256 Hash Reverse Decryptor — frequently asked questions
How can a SHA-256 hash be decrypted?
Because SHA-256 is mathematically irreversible, "decryption" refers to reverse dictionary lookup. The tool checks whether the 64-character hash matches the precomputed digest of common passwords, words, and phrases.
What is the difference between reversing MD5 and SHA-256?
SHA-256 has a much larger output space ($2^{256}$ possibilities compared to $2^{128}$ for MD5) and no known practical collision attacks. Only dictionary lookups for common unsalted phrases can succeed.
Are my queries recorded in search logs?
Never. In accordance with Sada Files Core Mandate 1 and Mandate 6, queries and lookup targets are never logged, tracked, or saved.
Can salted SHA-256 hashes be reversed here?
Salted hashes append secret or random strings before hashing, which renders dictionary tables ineffective. Only unsalted hashes of known words or passwords can be reversed.
What should I do if my SHA-256 hash is not found?
If the lookup returns no match, the plaintext likely possesses sufficient length or randomness to withstand common dictionary lookups.
