哈希识别器 — Hash Identifier tells you which algorithm most likely produced a digest. It analyses the structure — length in hex characters, character set, and known constant prefixes like the famous MD5 digest of an empty string — and ranks the plausible algorithms.
Identification is pure string analysis in your browser. Your digest never leaves this page.

哈希识别器是什么？
Hash Identifier tells you which algorithm most likely produced a digest. It analyses the structure — length in hex characters, character set, and known constant prefixes like the famous MD5 digest of an empty string — and ranks the plausible algorithms.
Length is strong evidence: 32 hex characters means a 128-bit digest (MD5 or NTLM), 64 means 256-bit (SHA-256 family), 128 means SHA-512 or BLAKE2b. For the four algorithms Uttir can compute locally, you can hash a known text and compare digests to confirm the guess.
使用方法
-
Paste the digest
Whitespace, colons, and a 0x prefix are tolerated.
-
Read the candidates
Matches are ranked by length evidence.
-
Confirm by comparison
Hash a known input locally and compare digests when possible.
示例
A 32-character digest
d41d8cd98f00b204e9800998ecf8427e is 32 hex chars and matches the known MD5 digest of an empty string — identified as MD5.
d41d8cd98f00b204e9800998ecf8427e
结果： MD5 (length match + empty-input constant match)
