Hash Type detector
Identify a digest or encoded-value format
Paste up to 100 values, one per line. The detector examines length, alphabet, separators and characteristic prefixes to return ranked candidates. It recognizes common hexadecimal hashes, bcrypt, Argon2, PBKDF2, JWT, UUID, Base64 and several structured formats.
Why several answers can be valid
A visual format does not always identify the algorithm. MD5 and NTLM, for example, both produce 32 hexadecimal characters. The score measures how well a value fits a format, not certainty about its origin.
Use the source context
Review the software, protocol or database that produced the value. A prefix such as $2b$ is highly characteristic of bcrypt, while an unprefixed hexadecimal string often remains ambiguous. Result links open the relevant tool directly.
Practical notes
Length and alphabet provide hypotheses, but several algorithms can share exactly the same format.

Frequently asked questions
Why are both MD5 and NTLM suggested?
Both produce 32 hexadecimal characters. Their source context is needed to distinguish them.
Does a 100% score prove the algorithm?
It mainly means a prefix or structure is highly characteristic; context still matters.
Is an encoding a hash?
No. Base64 and hexadecimal encoding are reversible, unlike a hash function.
