Frequently Asked Questions
A cryptographic hash function takes an input of any size and produces a fixed-size digest. It is deterministic, one-way, and collision-resistant. Hash functions are used for file integrity verification, password storage, digital signatures, and malware identification.
SHA-256 is the recommended default. MD5 and SHA-1 are considered broken and should only be used for non-security purposes like checksums. In malware analysis, MD5 and SHA-256 are both commonly used as file identifiers across threat intelligence platforms.
Yes! After generating a hash, click "Search on mlab" to look it up in our threat intelligence database. Mlab aggregates data from multiple sources to tell you if a file hash is associated with known malware.
